I have been working through the Autodesk Forge Sample App tutorial.
WHen I click the button to connect with my account I get this error;
{"developerMessage":"The required parameter(s) redirect_uri not present in the request","errorCode":"AUTH-008","more info":"https://forge.autodesk.com/en/docs/oauth/v2/developers_guide/error_handling/"}
If you get this error, you probably trying a 3 legged oauth flow. And it means that you did not provide the callback url in the request. Since you did not say which tutorial you have been using, let me point you to 2 sources - the Forge documentation tutorial here or the Learn Forge tutorial here
In both case, it is important to have the callback url defined in the application page on the Forge portal - If you are using your local machine, it should be something like http://localhost:3000/mycallback. The learnforge material tells you to define it as (see here):
http://localhost:3000/api/forge/callback/oauth
where the documentation tutorial says to use
http://sampleapp.com/oauth/callback
but here they assume you own the domain sampleapp.com which is probably not true. You need to replace sampleapp.com by your own domain or the localhost:port when developing your webserver on your local machine. Note it is important to use your true domain vs localhost when you'll run the code on your server, and update both your application page and your code to use the same definition. I usually setup 3 applications (dev: with localhost:3001, staging: with myapp-staging.autod3sk.net, and production: with myapp.autod3sk.net) - this is to avoid to have to edits keys all the time and make the application deployment a lot easier.
Now that your application is setup, you need to use that URL in your request as documented in the Oauth API. But all parameters should be URL encoded, otherwise the / character will be misinterpreted by the server. Failing to pass the correct and encoded URL parameter in the request will result in the error you are seeing.
Here is an example:
https://developer.api.autodesk.com/authentication/v1/authorize \
?response_type=code \
&client_id=MYCLIENT_ID \
&redirect_uri=MY_ENCODE_CALLBACKURL \
&scope=REQUIRED_SCOPES
after replacing the placeholders, it should look like this
https://developer.api.autodesk.com/authentication/v1/authorize\
?response_type=code\
&client_id=oz9f...k2d\
&redirect_uri=http%3a%2f%2flocalhost%3a3000%2fapi%2fforge%2fcallback%2foauth\
&scope=data%3aread
Copy this in your browser, and after logging and the consent page, the service should return to your browser with a URL like this:
http://localhost:3000/api/forge/callback/oauth?code=wroM1vFA4E-Aj241-quh_LVjm7UldawnNgYEHQ8I
Because, we do not have a server yet, the browser will error, but you can clearly see the URL returned to you with a code. You know need to copy that code into another request to get the final token. Here, we will use curl, but ideally both request and the callback should be handled by your server code.
curl 'https://developer.api.autodesk.com/authentication/v1/gettoken' \
-X 'POST' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'client_id=oz9f...k2d' \
-d 'client_secret=eUr...Q1e' \
-d 'grant_type=authorization_code' \
-d 'code=wroM1vFA4E-Aj241-quh_LVjm7UldawnNgYEHQ8I' \
-d 'redirect_uri=http://localhost:3000/api/forge/callback/oauth'
Ideally, all this needs to be done in your server code, like the learnforge tutorial teach you to do.
I am using postman to test an API I have, all is good when the request does not contain sub-domain, however when I add a sub-domain to URL I am getting this response.
Could not get any response
There was an error connecting to http://subdomain.localhost:port/api/
Why this might have happened:
The server couldn't send a response:Ensure that the backend is working
properly
Self-signed SSL certificates are being blocked:Fix this by turning off
'SSL certificate verification' in Settings > General
Proxy configured incorrectly Ensure that proxy is configured correctly
in Settings > Proxy
Request timeout:Change request timeout in Settings > General
If I copy the same URL from postman and paste it into the browser I get a proper response, is there some kind of configurations I should do to make postman work with sub-domains?
First Go to Settings in Postman:
Off the SSL certificate verification in General Tab:
Off the Global Proxy Configuration and Use System Proxy in Proxy Tab:
Make Request Timeout to 0 (Zero)
Configure Apache:
If the above changes resulted in a 404 response, then continue reading ;-)
Users that host their site locally (like with XAMP and/or WAMP), may be able to visit their virtual sites using https:// prefixed address, but it's a lie, and to really enable SSL (for each virtual-site), configure Apache like:
Open httpd-vhosts.conf file (from Apache's conf/extras directory), in your preferred text editor.
Change the virtual site's settings, into something like:
<VirtualHost *:80 *:443>
ServerName my-site.local
ServerAlias *.my-site.local
DocumentRoot "C:\xampp\htdocs\my-project\public"
SSLEngine on
SSLCertificateFile "path/to/my-generated.cert"
SSLCertificateKeyFile "path/to/my-generated.key"
SetEnv APPLICATION_ENV "development"
<Directory "C:\xampp\htdocs\my-project\public">
Options Indexes FollowSymLinks
AllowOverride All
Order allow, deny
Allow from all
</Directory>
</VirtualHost>
But of course, generate a dummy-SSL-certificate, and change all file paths, like from "path/to/my-generated.cert" into real file addresses.
Finally, test by visiting the local site in the browser, but using http:// (without S) prefixed address; Apache should now give error like:
Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.
I had the same issue. It was caused by a newline at the end of the "Authorization" header's value, which I had set manually by copy-pasting the bearer token (which accidentally contained the newline at its end)
If you get a "Could not get any response" message from Postman native apps while sending your request, open Postman Console (View > Show Postman Console), resend the request and check for any error logs in the console.

Hi This issue is resolved for me.
setting ->general -> Requesttimeout in ms = 0
If all above methods doesn't work check your environment variables, And make sure that the following environments are not set. If those are set and not needed by any other application remove them.
HTTP_PROXY
HTTPS_PROXY
Reference link
For me it was the http://localhost instead of https://localhost.
When getting the following error,
you need to do the following.
Step 1:
In Postman, click the wrench icon, go to settings, then go to the Proxy tab.
Step 2:
Create a custom Proxy. This article explains how to create a custom proxy.
After you create the custom Proxy, make sure you turn the Proxy toggle button to off. I put 61095 in for the proxy server and it worked for me.
Step 3 :
Success
I came up with this solution
In postman go to setting --> proxy
And off Global Proxy Configuration
on the Use System Proxy
And go to windows host configure file
'C:\Windows\System32\drivers\etc\hosts'
Open that file in administrator mode
And add the sub domain to hosts file
For me what worked was to add 127.0.0.1 subdomain.localhost to my host file. On OSX that was /etc/hosts. Not sure why that was necessary as I could reach the subdomain from chrome.
In postman go to setting --> proxy
And off Global Proxy Configuration
For me, it was that route that I was calling in my node server wasn't returning anything. Adding
return res.status(200).json({
message: 'success!',
response: 'success!'
});//
to the route I was calling resolved the issue.
You mentioned you are using a CER certificate.
According to the Postman page on certificates.
Choose your client certificate file in the CRT file field. Currently, we only support the CRT format. Support for other formats (like PFX) will come soon.
The name of the extension CER, CRT doesn't make the certificate that type of certificate but, these are the excepted extensions names.
CER is an X.509 certificate in binary form, DER encoded.
CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding.
You can use OpenSSL to change a CER file into a CRT file. I have not had good luck with it but it looks like this.
openssl x509 -inform PEM -in certificate.cer -out certificate.crt
or
openssl x509 -inform DER -in certificate.cer -out certificate.crt
Postman for Linux Version 6.7.1 - Ubuntu 18.04 - linux 4.15.0-43-generic / x64
I had the same problem and by chance I replaced http://localhost with http://127.0.0.1 and everything worked.
My etc/hosts had the proper entries for localhost and https://localhost requests always worked as expected.
I have no clue why changing localhost for http with 127.0.0.1 solved the issue.
None of these solutions works for me. Postman is not sending any request to the server because postman is not finding the host. So, if you modify your /etc/hosts to
127.0.0.1 localhost
127.0.0.1 subdomain.localhost
It works for me.
For me the issue was that the Content-Length was too big. I placed the content of the body in NotePad++ and counted the characters and put that figure in PostMan and then it worked.
I know it does not directly answer why the op's sub-domain was not working but it might help out someone.
In my case it was invisible spaces that postman didn't recognize, the above string of text renders as without spaces in postman.
I disabled SSL certificate Validation and System Proxy even tried on postman chrome extension(which is about to be deprecated), but when I downloaded and tried Insomnia and it gave those red dots in the place where those spaces were, must have gotten there during copy/paste
For anyone who experienced this issue with real domain instead of localhost and couldn't solve it using ANY OF THE ABOVE solutions.
Try changing your Network DNS (WIFI or LAN) to some other DNS. For me, I used Google DNS 8.8.8.8, 8.8.4.4 and it worked!
solution is very simple if you are using asp.net core 2 application . Inside ConfigureServices method inside startup.cs file all this line
services.AddMvc()
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
.AddJsonOptions(x => x.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore);
You just need to turn SSL off to send your request.
Proxy and others come with various errors.
My issue was by putting wrong parameters in the header,
the requested parameters was
Authorization: Token <string>
and is was trying
Authorization Token: <string>
After all the above methods like turning OFF SSL certificate verification, turning ON only Use System Proxy and removing HTTP_PROXY and HTTPS_PROXY system environment variables, it worked.
Note: Had to restart the Postman app, since the environment variables were changed.
Unchecking proxy and SSL Certificate Verification didn't work for me.
Unsetting PROXY environment variables did the trick.
export http_proxy=
export ftp_proxy=
export https_proxy=
Change to the directory where Postman is installed and then:
./Postman
In my case, MVC wasn't able to serialize the results (I accidentally used a model instead of DTO). I debugged down to passing a simple string, which worked. Once I fixed the serialization it all came up.
In my case the (corporate) proxy was using a self-signed SSL certificate which Postman disliked. I discovered it by activating
View->Show Postman console
and retrying the request. The console then showed the certificate error. In
Settings->General
I disabled
SSL certificate verification.
The solution for me, as I'm using the deprecated Postman extension for Chrome, to solve this issue I had to:
Call some GET request using the Chrome Browser itself.
Wait for the error page "Your connection is not private" to appear.
Click on ADVANCED and then proceed to [url] (unsafe) link.
After this, requests through the extension itself should work.
In my case it was a misconfigured subnet. Only one of the 2 subnets in the ELB worked.
I figured this out by doing a nslookup and trying to curl the returned IPs directly. Only one worked.
Postman just kept using the misconfigured one.
I had the same issue.
Turned out my timeout was set too low. I changed it to 30ms thinking it was 30sec. I set it back to 0 and it started working again.
I got the same "Could not get any response" issue because of wrong parameter in header. I fixed it by removing parameter HOST out of header.
PS: Unfortunately, I was pushed to install the other software to get this information. It should be great to get this error message from Postman instead of getting general nonsense.
In my case, I forgot to set the value of the variable in the "CURRENT VALUE" field.
I just experienced this error. In my case, the path was TOO LONG. So url like that gave me this error in postman (fake example)
http://127.0.0.1:5000/api/batch/upload_import_deactivate_from_ready_folder
whereas
http://127.0.0.1:5000/api/batch/upld_impt_deac_ready_folder
worked fine.
Hope it helps someone who by accident read that far...
I am told to upload an image to a server by sending a JSON as a request.
JSON is sth like below:
{"action":"setMap","data":{"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}}
I do not know how to use TELNET to POST a JSON.
i guess i should write something like below
terminal>telnet my.ip.num.ber port
POST /setMap HTTP/1.1
but dont know how to continue.
Should i write
DATA : {"action":"setMap","data":{"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}}
How can i get the JSON sent?
I can't understand why you want to use Telnet. Telnet can be useful to quickly test chatty protocols, and even if HTTP is chatty to some degree, it's very cumbersome to upload an image (plus, from the given service name, setMap, I guess the service doesn't really let you upload an image, but just insert a record in the database pointing to an image accessible on another service).
What you are asking is something like:
$ telnet example.com 80
> POST /setMap HTTP/1.1
> Host: www.example.com
> Content-Type: application/json; charset=utf-8
> Content-Length: 1234
>
> {"mapName":"myMapName","mapURL":"http://tinypic.com/myimg"}
>
Note that it's just an example. You have to replace connection parameters (host, port), content-type, content-length and the actual JSON data - and this we can't know because depends on the actual service implementation.
My flash game needs to connect to my PHP Socket Server. Because of security things, a policy file has to be send to the flash client when it tries to connect.
The following is what I've done.
In Actionscript / Flex 3 / Flash:
Security.loadPolicyFile("http://[SERVER.IP]:9000/crossdomain.xml");
socket.connect(hostName, port); //connect to the socket
[rest of original code]
To make the socket server respond on the request, I added the following to the server:
elseif (preg_match("/policy-file-request/i", $buffer) or preg_match("/crossdomain/i", $buffer)) {
socket_write($socket, '<?xml version="1.0"?><cross-domain-policy><site-control permitted-cross-domain-policies="all"/><allow-access-from domain="*" to-ports="9000" /></cross-domain-policy>');
unset($read_sockets[array_search($socket, $read_sockets)]);
socket_shutdown($socket, 2);
socket_close($socket);
I however get the following error: "Ignoring policy file at (URL) due to missing Content-Type." So, I tried to fix this by adding a header right above my xml code:
socket_write($socket, "Content-Type: text/xml\n");
Unfortunately, I still get the same error. Am I giving the content type in a wrong way?
You need to return a valid HTTP response if you are going to use:
Security.loadPolicyFile("http://[SERVER.IP]:9000/crossdomain.xml");
If the flash is going to connect to your PHP socket server, just skip the above line and it will try the port itself and expect raw data instead of a HTTP response.
Try sending this:
HTTP/1.1 200 OK\r\nContent-Type: text/xml\r\n\r\n
Make sure nothing is sent before this.
Also, send a \r\n before the socket is closed.
you can load the policyfile from any port of the server using Security.loadPolicyFile() ... maybe you should simply serve it per http on port 80, load it from there and then connect to the server ...
also, by default, i think flashplayer 9 (upwards from some minor version) sends a policyfile request to port 943 by default ... so you might put a server there, to do that ...
a little side note: PHP was never designed for socket servers and is not very good at that ... if you can, try using Java, or NekoVM, that you can use with Haxe ... also Haxe remoting, as well as ThreadedRemotingServer might be of interest to you ... there's some good and clear tutorials on the Haxe site ...
Try it with \r\n after the Content-Type.
socket_write($socket, "Content-Type: text/xml\r\n");
Shouldn't you be using a xmlsocket on port 843?
if(trim($buffer) == '<policy-file-request/>') {
$policy_file =
'<'.'?xml version="1.0" encoding="UTF-8"?'.'>'.
'<cross-domain-policy xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.adobe.com/xml/schemas/PolicyFileSocket.xsd">'.
'<allow-access-from domain="*" to-ports="*" secure="false" />'.
'<site-control permitted-cross-domain-policies="master-only" />'.
'</cross-domain-policy>';
socket_write($socket, $policy_file.chr(0));
}
works fine for me, the client will request a policy file, disconnect, then reconnect after receiving the policy file
