I have this curl example:
curl -i -X GET -H "Content-Type:application/json" https://dev.ga.coach/intervention/:getworse/ -d '{"user_id": "012ab3", "section_id": "6"}'
When I run it through cygwin it's working properly! When I'm trying to import it in postman then it shows it as POST and I get the following response.
<h1>Not Found</h1>
<p>The requested URL /intervention/ was not found on this server.</p>
When I test https://dev.ga.coach/intervention/:getworse/ through web browser, this is what I see:
cURL allows you to include a payload on a GET request but the HTTP specification says:
A payload within a GET request message has no defined semantics;
sending a payload body on a GET request might cause some existing
implementations to reject the request.
When you try to make the same request with Postman, you are experiencing it "rejecting" the request. In this case, the rejection comes in the form of it converting to a POST request instead.
It would be appropriate to include a JSON payload on a POST request, but since it looks like you are trying to GET information you should move the data to the URL instead.
For example:
https://dev.ga.coach/intervention/012ab3/6/:getworse/
This will require you change your server-side code (which you, presumably, can do since you said I'm developing the rest-apis) to read the data from the new location.

I am trying to make an API call to Microsoft's form recognizer to analyze a form against a custom model and I can't figure out how to do it.
Here is the documentation on the API
https://westus2.dev.cognitive.microsoft.com/docs/services/form-recognizer-api/operations/AnalyzeWithCustomModel
The request body is blank and I don't really know how that ought to be formatted in order to be sent off.
If you look at the POST Train model method, I was able to use that request body to send make that api call work. This indicates that the problem is me and not the API.
I have successfully done this with curl through command line...
curl -X POST "https://formrecognizerbp.cognitiveservices.azure.com/formrecognizer/v1.0-preview/custom/models/[MODEL ID]/analyze" -H "Content-Type: multipart/form-data" -F "form=#\"C:\Temp\Capture1.jpg\";type=image/jpeg" -H "Ocp-Apim-Subscription-Key: [SUBSCRIPTION ID]"
I don't really know/can't figure out how to convert that into a request body similar in format to what the POST Train Model method has.
I keep getting this error because I don't know how to format the request properly.
Internal : Unexpected error Error during Web API HTTP Request
HTTP Status Code: 400
HTTP Response Content: {"value":{"error":{"code":"BadRequest","message":"Could not process incoming request: 'Missing content-type boundary.'. Please ensure that it is well-formed."}},"formatters":[],"contentTypes":[],"statusCode":400}
So I guess formatters and contentTypes are the missing pieces but would that just be the file path and the image/jpeg parts of the curl ?
The /trainCustomModel API expects the data to be present on the Azure Blob storage. The request body to this request needs to contain a valid SAS URL to the training data. Once you successfully create a custom trained model ID, you could use that to analyze the forms. The /AnalyzeWithCustomModel API expects the data to be on your local file storage. Please ensure that you have the replaced the ModelId, API Subscription Key (Note this is not the same as subscription ID) and the local path to the image correctly.
The issue was that I did not realize that the curl script was overwritting the multipart/form-data Content-Type with image/jpeg and when I was trying to build out this call differently I was forcing a multipart/form-data Content-Type on what was a jpeg.
When I make a request, I get a response in XML, but what I need is JSON. In the doc it is stated in order to get a JSON in return: Use the Accept: application/json HTTP Header.
Where do I find the HTTP Header to put Accept: application/json inside?
My guess is it is not suppose to be inside the URL-request, which looks like:
http://localhost:8080/otp/routers/default/plan?fromPlace=52.5895,13.2836&toPlace=52.5461,13.3588&date=2017/04/04&time=12:00:00
You guessed right, HTTP Headers are not part of the URL.
And when you type a URL in the browser the request will be issued with standard headers. Anyway REST Apis are not meant to be consumed by typing the endpoint in the address bar of a browser.
The most common scenario is that your server consumes a third party REST Api.
To do so your server-side code forges a proper GET (/PUT/POST/DELETE) request pointing to a given endpoint (URL) setting (when needed, like your case) some headers and finally (maybe) sending some data (as typically occurrs in a POST request for example).
The code to forge the request, send it and finally get the response back depends on your server side language.
If you want to test a REST Api you may use curl tool from the command line.
curl makes a request and outputs the response to stdout (unless otherwise instructed).
In your case the test request would be issued like this:
$curl -H "Accept: application/json" 'http://localhost:8080/otp/routers/default/plan?fromPlace=52.5895,13.2836&toPlace=52.5461,13.3588&date=2017/04/04&time=12:00:00'
The H or --header directive sets a header and its value.
Here's a handy site to test out your headers. You can see your browser headers and also use cURL to reflect back whatever headers you send.
For example, you can validate the content negotiation like this.
This Accept header prefers plain text so returns in that format:-
$ curl -H "Accept: application/json;q=0.9,text/plain" http://gethttp.info/Accept
application/json;q=0.9,text/plain
Whereas this one prefers JSON and so returns in that format:-
$ curl -H "Accept: application/json,text/*;q=0.99" http://gethttp.info/Accept
{
"Accept": "application/json,text/*;q=0.99"
}
Basically I use Fiddler or Postman for testing API's.
In fiddler, in request header you need to specify instead of xml, html you need to change it to json.
Eg: Accept: application/json. That should do the job.
Well Curl could be a better option for json representation but in that case it would be difficult to understand the structure of json because its in command line.
if you want to get your json on browser you simply remove all the XML Annotations like -
#XmlRootElement(name="person")
#XmlAccessorType(XmlAccessType.NONE)
#XmlAttribute
#XmlElement
from your model class and than run the same url, you have used for xml representation.
Make sure that you have jacson-databind dependency in your pom.xml

<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>

I would like to create HTTP GET request to REST API using the curl tool that comes with the Cloud Foundry command line interface (cf). The content/format of the request is described here, under "Retrieving a list of all currently deployed models:" subtitle. In short, the description gives me the url that I can make the request to, it also gives me the following "request example":
Content-Type: */*
Parameters:
Query Parameters:
accesskey: access_key from env.VCAP_SERVICES
I know how to retrieve all necessary parameters (i.e. the access keys, etc). The problem is that I am not sure how to interpret the above "request example" (is it header or body of the request?) and how to create curl command that will properly send the request.
I want to briefly describe what I have tried so far. When I try:
cf curl -X GET "http://{my_url}/model?accesskey={my_access_key}"
I always get the following response:
{
"code": 10000,
"description": "Unknown request",
"error_code": "CF-NotFound"
}
, when I try:
cf curl -X 'GET' http://{my_url}/model?accesskey={my_access_key}
, I think I actually get a response from the server:
<html>
<head><title>400 Bad Request</title></head>
<body bgcolor="white">
<center><h1>400 Bad Request</h1></center>
<hr><center>nginx</center>
</body>
</html>
Whenerver I try to use just "normal" curl (not the one that comes with the cf command line interface) the Bluemix Predictive Modeling service doesn't respond at all - the connection always times out. I'm not sure why, since Bluemix documentation says that any programming language can be used to make the REST API calls. In the future I would also like to use POST requests - an explanation of how to make one would be very helpful too.
Any help will be greatly appreciated.
You first need to "bind" an instance of the Predictive Model service to an app. When you have done it, you will have a "Show credentials" link below the app widget in your Bluemix dashboard. Click "Show credentials", and you will see a JSON object (which happens to be the VCAP_SERVICES value that Bluemix sets as environment variable for your app), for example:
{
"pm-20": [
{
"name": "Predictive Modeling-i6",
"label": "pm-20",
"plan": "free",
"credentials": {
"url": "https://ibmpmsrvus1.pmservice.ibmcloud.com:8443/pm/v1",
"access_key": "xxxyyyzzz"
}
}
]
}
(I have just removed my own credentials).
Finally for the Curl command, use the "url" above as root of your API, and add a query parameter "?accesskey=xxxyyyzzz" (whatever credentials you have on your own) to all API calls. For example, I add /model to my URL to query my list of models (none created):
curl -X GET "https://ibmpmsrvus1.pmservice.ibmcloud.com:8443/pm/v1/model?accesskey=xxxyyyzzz"
which returns
[]
(as I have not created any models). Note that you will likely need to quote the URL, since the access key contains characters that may mess up your shell command.
I explicitly used "-X GET": You will want to do "-X PUT" in some commands (PUT HTTP method), and most likely you can use "-d #" to upload a file as form data payload:
curl -X PUT -d #mymodelfile "https://..."
I have this particular cURL statement that I am trying to figure out the equivalent for it in an HTTP Request.
curl -X POST --upload-file movie-data-2013.json doc-movies-123456789012.us-east-1.cloudsearch.amazonaws.com/2013-01-01/documents/batch --header "Content-Type:application/json"
So far the HTTP Request equivalent I am able to compile is below:
Set oHTTPRequest = Server.CreateObject( "MSXML2.XMLHTTP.3.0" )
oHTTPRequest.Open "POST" _
,"doc-movies-123456789012.us-east-1.cloudsearch.amazonaws.com/2013-01-01/documents/batch" _
False
oHTTPRequest.setRequestHeader "Content-type", "application/json"
oHTTPRequest.Send
For the most part I should be set, except there's one part it's missing, and I'm unsure how it's appended to the request.
There is a part in cURL that says: --upload-file movie-data-2013.json
Not sure how it applies in an HTTP Request. Does anyone how this applies?
I'd recommend trying .Net's built-in HttpWebRequest class over MSXML. There is an example of uploading text data on MSDN using the GetRequestStream method. You should be able to easily modify the sample to instead read the data from a file, for example using File.ReadAllBytes, and then write the returned data to the request stream.
I have been given a url .. www.abc.com/details and asked to send my name and phone number on this url using POST. They have told me to set the content-type as application/json and the body as valid JSON with the following keys:
name: name of the user
phone number: phone number of the user
Now i have no clue how to send this request! Will it be something like:
http://www.abc.com/details?method=post&name=john&phonenumber=445566
or do i have to use java to send the same?
Please help
Based on what you provided, it is pretty simple for what you need to do and you even have a number of ways to go about doing it. You'll need something that'll let you post a body with your request. Almost any programming language can do this as well as command line tools like cURL.
Once you have your tool decided, you'll need to create your JSON body and submit it to the server.
An example using cURL would be (all in one line, minus the \ at the end of the first line):
curl -v -H "Content-Type: application/json" -X POST \
-d '{"name":"your name","phonenumber":"111-111"}' http://www.example.com/details
The above command will create a request that should look like the following:
POST /details HTTP/1.1
Host: www.example.com
Content-Type: application/json
Content-Length: 44
{"name":"your name","phonenumber":"111-111"}
You can post data to a url with JavaScript & Jquery something like that:
$.post("www.abc.com/details", {
json_string: JSON.stringify({name:"John", phone number:"+410000000"})
});
It is not possible to send POST parameters in the URL in a straightforward manner. POST request in itself means sending information in the body.
I found a fairly simple way to do this. Use Postman by Google, which allows you to specify the content-type (a header field) as application/json and then provide name-value pairs as parameters.
You can find clear directions at [2020-09-04: broken link - see comment] http://docs.brightcove.com/en/video-cloud/player-management/guides/postman.html
Just use your URL in the place of theirs.
You can use postman.
Where select Post as method.
and In Request Body send JSON Object.
In windows this command does not work for me..I have tried the following command and it works..using this command I created session in couchdb sync gate way for the specific user...
curl -v -H "Content-Type: application/json" -X POST -d "{ \"name\": \"abc\",\"password\": \"abc123\" }" http://localhost:4984/todo/_session
If you are sending a request through url from browser(like consuming webservice) without using html pages by default it will be GET because GET has/needs no body. if you want to make url as POST you need html/jsp pages and you have to mention in form tag as "method=post" beacause post will have body and data will be transferred in that body for security reasons. So you need a medium (like html page) to make a POST request. You cannot make an URL as POST manually unless you specify it as POST through some medium. For example in URL (http://example.com/details?name=john&phonenumber=445566)you have attached data(name, phone number) so server will identify it as a GET data because server is receiving data is through URL but not inside a request body
In Java you can use GET which shows requested data on URL.But POST method cannot , because POST has body but GET donot have body.
