I fetching data from an api end point.
When I use postman to send the request, I get an array of of objects (non empty).
However when I simply request it via the browser I get an array of empty objects...
Why is this happening?
You need to pass authorization token and Content-Type headers while making a request through the browser.
Browser only able to make a get request, it doesn't set header value(s) directly for you. You need to add extension of chrome like ModHeader, which will help you to set request and response header.
Moreover, I don't think you need to worry about it, as I assume you will need application internal call instead.

I am trying to call a Postman GET endpoint, and it is returning HTML and status 200, instead of a valid JSON response and status 200. It looks like it is not hitting the backend at all. I have a separate POST endpoint, which works fine and returns me a valid JSON response.
Could this be due to authorization headers? I am using the same authorization for both.
I managed to resolve the issue. I had to add a cookie header, which I got from the browser since I was able to call the service from the browser and I had authenticated on browser level.
I am trying to implement sample spring boot project and trying to retrieve result using POSTMAN application. But when using POSTMAN , I am not able to see that response for a GET request. But I can see by using browser properly. POSTMAN returning "Expected ':' instead of 't'" as result. But I can see result properly by using browser.
And my controller code is like the following,
#GetMapping("/check")
public List<Users> check() {
return (List<Users>) userObj.findAll();
}
Can anyone help me to find out why I am not able to see result using POSTMAN application please?
You are saying to postman (for that matter any client) that your api is producing json and instead you are returning just a string.
Check your header you will have a field called
Content-Type → application/json;charset=UTF-8
All you need to do is ensure you are sending valid json or remove that header entry so clients do not try to read it as json.
Or just to check you are getting right data by changing format from json to text in postman
You server application needs to understand the incoming request type. can you define the Content-Type=application/json and give a try.
I'm having trouble with getting my site normally loaded during the performance testing in Apache JMeter. Firstly I recorded the script (by BadBoy), containing authorization and visiting some pages, unavailable without login. Next, I exported it to JMeter, configured Regular Expression Extractor to get the csrftoken from the request right before the authorization request and it looks like it works just fine:
no errors in http-requests
But if to look at the tab "Response data" of every post-authorized request, the content isn't like correctly loaded page, it just starts page with the empty authorization form, i.e. in some way session is new though all the requests have the same session id and csrftoken in Cookie Data and in Set-Cookie (Sample result), appeared in authorization request result.
HTTP Cookie Manager is added.
Did anyone face this trouble?
UPDATE: I've conducted an experiment with transferring cookies from Chrome to Mozilla Firefox, copied 'csrftoken' and 'session id', and - voila! - it worked, I got the same authorized session in two browsers. Still have no idea what's wrong with JMeter
JMeter automatically treats HTTP Response Codes below 400 as successful, it doesn't perform any checks of response body. Most likely your Regular Expression Extractor failed, add a Debug Sampler and double check resulting variable value.
There could be also the following possible reasons:
You might need to send CSRF token in encoded/escaped form so using i.e. __urlEncode() function will be required. Or vice versa.
Application may expect the token in multiple locations, i.e. not only as a form parameter, but as an extra HTTP Header. In that case you will need to pass it via HTTP Header Manager
You might also want to try the new step-by-step debugger for JMeter to get to the bottom of the issue.
This is the default behavior of this token. 1. make sure where these tokens are passed. It might be passed multiple times. Check the header. Generally, "xref-token" is again passed.
It should be in exact format, decode it if required, also remove , or ; or /. You can also use fiddler.
The solution was found after recording a script by Blazemeter plugin in Chrome and further exporting it in '.JMX' format. Adding an HTTP Header Manager like this (with its special fields, of course) to each HTTP Request solved the problem.
I have a web crawler on Heroku and I'm trying to call the script from a POST request on Parse Cloud Code httpRequest but I receive a 403 forbidden response basically telling me the Referer Header didn't pass. How can I get past this?
Django's CSRF protection tests the Referer header: see https://docs.djangoproject.com/es/1.9/ref/csrf/#how-it-works. Browsers typically send that header to indicate the page that originated a request, but programmatic user agents don't (cURL, Python requests, and presumably Parse.Cloud.httpRequest) without being told to do so.
To add custom headers to a Parse request, see: Parse.Cloud.httpRequest call with HTTP request header (note the headers object).
That said, you also need to make sure you have a way to get the CSRF token to begin with, and include it either in a XCSRF-Token header or a form field (unclear from your question whether you are doing that).
I followed the example on http://docs.brightcove.com/en/video-cloud/media/references/reference.html#Video. The response gets shown in an iframe. However, I would like to be able to get the JSON response in order to store the data (i.e., Brightcove video ID) in my own database. I tried using AJAX post but Brightcove doesn't seem to accept post requests from a different origin. Is there a way to simply get the response data without displaying it in an iframe or in a separate window?
You can't get the response data in javascript since the API response does not include CORS headers. You'd need to do this in server-side code, which also has the advantage of not exposing your API token to the browser.
