Say for example I'm try to make a GET Request to www.testjson.com/json, However the response is retrieved from a different domain URL e.g. www.testjson.com/confirmJson.
Does Spring mvc support this, specifically restTemplate.exchange functionality.
I am currently doing this sort of thing, but I am getting an 500 status code (internal server error) and have no way of finding out what exactly is causing the error.
So can RestTemplate actually manage the redirect and provide the necessary JSON response or does it actually wait for the response from the url you provide hence the reason for getting the 500 internal server error?
It is possible to let a RestTemplate automatically follow a redirect.
The server must respond with a Http 3xx and the location header set.
The RestTemplate 'understands' this response and issues a new GET request to the returned location.
This should work with default spring configuration.

I am trying to create a test plan using jmeter.its for an API Post request, I have a header manager, bodydata, checked for spellings and the syntax seems to be correct. However, Im getting 400 response code with the following error shown in the attached image. Anyone with an idea how I can resolve this? Thank you. the error
Here is the request the request
The user doesn't have to be logged in, i have added a header manager, I have also noticed there header has a cookie value thats hard coded but it appears to be the same in every request. In the UI the API request returns 200 and thats what im expecting with the Jmeter script.
In its current form the question cannot be answered comprehensively.
HTTP Status Code 400 means that
The 400 (Bad Request) status code indicates that the server cannot or
will not process the request due to something that is perceived to be
a client error (e.g., malformed request syntax, invalid request
message framing, or deceptive request routing).
Check that your ${site} and ${csVersion} variables have their respective values using Debug Sampler and View Results Tree listener combination
Cross check headers sent by JMeter and by the "UI", the most important is Content-Type
Use a sniffer tool like Wireshark of Fiddler and capture the requests which are being sent by JMeter and the "UI", the requests must be exactly the same apart from dynamic parameters which need to be correlated
The issues was being caused by an anti-forgery cookie which was hard coded in the request.I used a regex to extract the value from a previous request and used a variable value from the regex to make sure the same value is being passed on to the request that was failing.
Facing a problem with protocols, please find the below code snippet.
If rquestedUrl starts with https, getResponse.getStatusLine().getStatusCode() is returning 200 whereas if the same rquestedUrl starts with http, getResponse.getStatusLine().getStatusCode() is returning 404.
But if I hit through browser I am able to access the requested file in both cases. Could you please let me know what could be the possible problems. (It is used as a filter before calling Orbeon, this is on the process of implementing WSSO.)
System.setProperty("javax.net.ssl.trustStore", "path_to_JKSFile");
System.setProperty("javax.net.ssl.trustStoreType","JKS");
System.setProperty("javax.net.ssl.trustStorePassword","password");
String rquestedUrl = "http://bigminds.web.mindblow.com/project/project1/views/files/Home.xhtml";
HttpClient client = HttpClients.createDefault();
HttpGet get = new HttpGet(rquestedUrl);
get.addHeader("Cookie", "somevalues");
get.addHeader("Host", "bigminds.mindblow.com:14325");
HttpResponse getResponse = client.execute(get);
It's likely that the endpoint you are hitting does not accept http requests, all requests must be though https. So there isn't anything wrong with your code, it's just not set up to properly integrate with the site you have there. Looking at the code it looks like you may need to have some type of session (ie: need to login) with the webserver to get the data you want.
I am writing a http handler for a server and I am looking directly at the http requests when they come in from different clients. I can easily deal with normal http requests. The problem occurs when I get a GET or POST request. I do not know how to access the data from the GET or the POST therefore I cannot continue. Could someone please point me in the direction of some where which deals with the issue on how to access the data. Thanks in advance.
Answer:
to do this:
In a GET request the data comes in the URL itself therefore just parse the URL from the HTTP request and look for the question mark and the arguments.
For a POST request there are 2 different ways however the main one means that the arguments are put in the body of the request like this:
q=hello&v=world
The length is specified in the request as well so if you need it is under Content-Length:
I need to send POST request and get json from it.
Create Http Context emopstest.pdc.org http
Set Request Header Content-Type application/x-www-form-urlencoded
Set Request Header Authorization Basic bG9naW46cGFzcw==
${dict}= Create Dictionary app_ids=18 where=ROWNUM<=2000
${value}= Stringify Json ${dict}
Set Request Body ${value}
HttpLibrary.HTTP.POST /auth_srv/services/auth/1/json/get_hazards
Show Response Body In Browser
Response Status Code Should Equal 200
${result_text}= Get Response Body
${result_json}= Parse Json ${result_text}
But this code returns to me 404...
What is wrong?
The 404 means that the server couldn't find the resource you requested. Usually that means the URL was wrong. Depending on how the server is configured, it could also mean that your authorization is wrong (ie: some applications will give a 404 in the case of bad authentication, so that an attacker isn't given a clue that the credentials are incorrect)
The server logs should have information that will help you track down whether you have an incorrect URL or that the server has a bug.
The answer to this little question will clear everything up for me.
If have a form tag that has a Get method and an action of some random script.
When I hit the submit button on the page, the Get Method is sent to HTTP and HTTP is what appends the query string to the url, the HTTP then returns a 20X status if the response is good and a 40X is a bad response? And our action goes to our webserver to run the script?
HTTP is transport and HTML is content. The Form submit calls a GET or POST request on the server depending on the action defined for the HTML form. The Form's arguments are appended by the Browser's form logic to the HTTP request, depending whehter GET or POST is used, they are attached to the request URL or put into the request body.
Then the request is handled on the server and the result is returned by the server logic (which can be a CGI, some perl script, a J2EE application etc.).
The server seponds with a HTTP status code (where everything below 300 is a success, and everything above 399 is an error - see here:HTTP staus codes ).
You are sending your form's data via HTTP using the "get" request. HTTP is a protocol and not a server. Your request is handled by a server who knows how to handle the HTTP protocol, eg. Apache.
The server processes the data and sends back a response. As you mention there are different kind of responses. 404 is best known (document not found).
The script is not run on the server, it is run on the client (the browser).
HTML is the markup code that describes the structure of the page. Browsers interpet the HTML code they receive and construct your page from it. Check here for more details: Wikipedia: HTML
The HTTP is the protocol used by the browser to talk to the server. Check this for more details: Wikipedia again: HTTP
