I want to simulate a fake 404 status code from the backend to see how my website will behave.
I don't want to mock fake response status in the code I would like to use some tools.
Cause sometimes I want to test it on the production which has version x and I don't want to waste time downloading this code and checking if there it is working.
Just simply mock response header status code for some test value like 404 for the fast check.
I tried to use software like Requestly - chrome extension.
And configured it like :
Modify response for header status put value 404 for google.com site.
But when I open google.com site I got status 200:
Do you know how can I change the status code of the given request?
Maybe by using different soft?
Status is not an HTTP response header. Status Code is an HTTP response code and Chrome does not allow to modify the response code of a request. There are two possible ways to solve this using Requestly
1-Step solution using Requestly Desktop App (Reliable & Guaranteed to work)
You can use any MITM proxy to intercept the request and simulate the status code. However, given my experience with Requestly, I'd explain how you can do it with Requestly Desktop App
Install Requestly Desktop App,
Go to Rules Tab and Click on New Rule
Select Modify Response
Define the exact URL (or Pattern) and define the status code. That's it.

Using Requestly Browser Extension (2-Step Process, Should Work in most sites but there could be some CORS Issues)
Install Requestly
Use Requestly Mock Server and create a new mock which serves 400 or 404
Use Requestly to set up a Redirect Rule which redirects your original request to the URL of your mock request
Here are a couple of examples using the extension
Simulate 500 in Twitter Create Tweet API
Simulate 404 in BlinkIt Search API
Footer Notes
Desktop App-based solution is more reliable and guaranteed to work while Extension-based solution has technical limitations and there may be some CORS Issues depending upon your backend So prefer to use Solution 1.
PS - I built Requestly (& still building it with lots of heart)
In DevTools on the Network panel, right click a resource and select Block Request URL or Block Request Domain.
Does that help in your use case?
Try using ModResponse: https://chrome.google.com/webstore/detail/modresponse/bbjcdpjihbfmkgikdkplcalfebgcjjpm. You can add "Replay response" on the URL that you want to replay, visit that URL, then open up ModResponse again to edit the HTTP status code. You can also use it to edit the HTTP response body and header as well.

The axios.post request doesn't work without proxy.
I am new in react js and using create-react-app
When I use proxy attribute in package.json and give it my http://url:port in my axios.post I start from /api/...
I do not need any config like headers or allow access. And I don't need to stringy data.
My back-end is java using Apache Tomcat and in back-end I have CORS filter that only allows application/json
requests. When I use postman if the header doesn't match , Apache refuses the request by 415 unsupported media type.
The problem begins from where I want to use npm run build. so there is no package.json and I should bring my full url to axios.post's url part : http://url:prot/api/..
Then I removed the proxy part from package.json
Since that I haven't seen any response from java or even it doesn't refuse the request in http monitoring or Apache Log part (in Netbeans)
I did two small things and something changed!
1-Adding JSON.stringfy before data
2-Adding headers Content-Type:Application/json
Now the request is observable in Netbeans (the back-end) BUT the messege is unsupported media type although i have added to axios.post's config(and itself caused the request received )!!!
there is some thing else : when I use the fire fox CORS enable adds on every things goes grate but only with that...
This is my first project. please explain like I'm 5! I do not know anything more!
Or if someone has any better way; is there any way i can use axios.post without package json proxy?
How does one take an HTTP request and redirect it to proxy (on an ad-hoc basis, assuming browser is on no-proxy)?
For example: I want to access http://www.stackoverflow.com/questions.
In terms of the API, this request would look like this:
Method: Get
Url: http://www.stackoverflow.com/questions
Headers
Host: www.stackoverflow.com
More-Headers: More-Values
If I have to send the same request to proxy, I need to add a proxy authorization header. I also need to change the URL to http://www.myproxy.com. How do I specify the URL of the website that I want to visit?
In terms of actual coding:
In onBeforeRequest callBack- I change the URL by returning {redirectUrl: https://www.myproxy.com}
In onBeforeSendHeaders callBack- I add the proxy auth header. I leave the Host header as is.
Where and how do I mention the URL of the target website I need content from?
The webRequest API won't let you do what you're asking, you need the browser to handle the proxying. The proxy API is meant to provide a way to do this, it is implemented in Chrome and is currently (August 2016) being implemented in Firefox (tracking bug is https://bugzilla.mozilla.org/show_bug.cgi?id=1283639).
the box appears in below snapshot is neither alert box,prompt box nor confirm box. then what is this? how can i create the same thing like this?
It's a BasicAuth prompt, if your server return a request for BasicAuth it will get handled by the browser.
It happens when the browser receives a response with a header that looks like this, "insert realm" can be almost anything:
WWW-Authenticate: Basic realm="insert realm"
Usually the web browser handles it by itself and shows that kind of prompt. By the way it's unrelated to the web server as it's part of the protocole. If you happen to run an application server, you'll have to send the header above in a response and expect an Authorization header back from the "web client".
If you run apache, nginx, you can check simply for BasicAuth and you should be able to find documentation on how to set it up.
Read more here: BasicAuth
If you have enough courage you can read the RFCs
This is a simple HTTP Authentification, like the one you can setup with a ".htpasswd" file on Apache and so on.
You can't do it with Javascript (it's on server-side), in PHP it would be like this
When making an HTTP request (using URLLoader, for example) that results in a redirect, is it possible to access any of the URLs in the redirect chain?
For example, let's say that the following happens:
We make a request to example.com/a.gif
example.com redirects to example2.com/b.gif
example2.com redirects to example3.com/c.gif
I've stared at the documentation for URLLoader and its various events for a while, and it doesn't seem like there's a way to either:
Instruct URLLoader to not follow redirects
Access any of the URLs involved after the initial request
Does anyone know if there's a way to do this? I'm not attached to using URLLoader, so if there's another class that supports this functionality, I'd be fine with using it.
Can anyone point me in the right direction? Thanks in advance!
Edit - I should clarify: I know how to detect the redirects outside of AS3 using a DOM debugger. I'm specifically interested in accessing the redirect chain within AS3. It would appear that it's possible using the AIR player via the HttpStatusEvent, but the relevant properties aren't available when using Flash Player.
Edit 2 - I've also tried using an HTTP client lib (as3httpclientlib, to be specific). This works except for the fact that it loads cross-domain policies from port 843 rather than by making an HTTP request to /crossdomain.xml. The context I'm working in requires the latter, so using something with Socket underlying it won't work unless there's a way to force Socket to load cross-domain policies from HTTP instead of port 843.
The redirects are generally in place because the original URL shouldn't be used anymore. The file doesn't exist at example.com/a.gif so in theory you don't need to know about it. Why do you need the intermediate request path?
I'm not aware of an actionscript way of finding the redirect chain for any request, but if you want to do it for a specific chain you can use HttpFox for Firefox, or hit f12 in google chrome and look at the network tab when making a request to the URL that redirects. This will only work if the client is redirected by the server to the new address (a HTTP 302 responce or similar.) If the server chooses to return the contents of example3.com/c.gif when someone's browser asks for example.com/a.gif there is nothing you can do.
I'm trying to replicate a request I make on a website (ie zoominfo.com) using the same http POST parameters using chrome rest console, but it fails for some reason. I'm not sure if there is a missing field or it's not working because the origin of the request isn't valid.. can someone point me out in the right direction? Below is a detailed explanation of the experiment:
ORIGINAL CASE
basically if I go to zoominfo.com (registered and all) I see a form page that I need to fill:
if I hit enter.. the site makes an ajax call. If I open the chrome web dev tools, and open the network tab, I see the details of the ajax call:
notice the body of the POST has the name John Becker in it:
{"boardMember":{"value":"Include","isUsed":true},"workHistory":{"value":"CurrentAndPast","isUsed":true},"includePartialProfiles":{"value":true,"isUsed":true},"personName":{"value":"john%20becker","isUsed":true},"lastUpdated":{"value":0,"isUsed":true}}
the response is shown under the respones tag:
WHAT I'M TRYING TO DO
basically replicate what i've done above using a REST console (note: so there is nothing illegal here.. i'm just replacing a chrome browser action with a rest client action.. i'm not hacking anyone and i'm not getting information I can't get the normal way, but if someone feels otherwise.. please let me know)..
so I plug in the same parameters as above into the rest console:
now i'm not sure about authentication.. but just to be safe, i entered the same user name and pwd i have for the site into the REST console:
but then I keep on getting an error as a response to my rest console's request:
UPDATE: CORRECT ANSWER:
so according to JMTyler's answer.. I had to simply include criteria in the RAW body, and convert it to url encoding.. in addition to that, I had to explicitly set the encoding in the rest console body..
looking at the chrome inspector more closely, it turns out that I simply had to click on view source:
to get the url-encoded value that I needed to put in the RAW body in the rest console:
I also had to set encoding to gzip,deflate,sdch and things worked fine!
The form is posting all that JSON under the field criteria. You can see this in the screencap of the chrome dev console you posted.
Just start your raw body in rest console with criteria= and make sure the json has been url-encoded. That should do it.
No authentication is needed because none is passed through the headers in your screencap. Any cookies you have when you load the page normally will also be loaded through rest console, so you don't need to worry about explicitly setting them.
Reading your problems I'll make an educated guess:
zoominfo does not provide an RESTful API.
Rest-Console understands and uses HTTP Authentication, which is different from the authentication handler zoominfo implemented.
A possible way to work around may be:
Make a call to the login-page via rest console. you'll get back cookies and a lot more.
In subsequent requests to zoominfo be sure to include those cookies (likely holding some session information) in your request, therefore acting like a browser.
