Query parameter not being extracted - JAX-RS and Jersey - java

I'm using Jersey 2.19 to implement a REST API but I'm having difficulty using #QueryParam to extract the query parameters from a POST request even though my resource method is being called.
This is my resource method:
#POST
#Produces(MediaType.TEXT_PLAIN)
public Response test(#QueryParam("test-param") String testParam)
{
String response = "testParam is: " + testParam + "\n";
return Response.status(Response.Status.OK).entity(response).build();
}
I'm using cURL to submit the HTTP POST request as follows:
curl -X POST http://192.168.0.2:8080/myApp/test --data test-param=Hello
The value returned is always null.
What am I doing wrong?

The --data in curl will provide the whole text test-param=Hello. The correct way to request it is:
curl -X POST http://192.168.0.2:8080/myApp/test?test-param=Hello

try to use curl -X POST '192.168.0.2:8080/myApp/test?test-param=Hello';
-d, --data
(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to -F, --form.

can we use content type octet stream and json together?

I have created a one rest service for uploading file.
My service consume Stream for file and Map of String for some info.
#RequestMapping(value = "/upload" , method = RequestMethod.POST)
public void upload(InputStream file,Map<String, String> fileInfoMap) {}
If yes then how to call service with POSTMAN?
if not then please suggest some alternatives?
add multipart/mixed content_type in postman , under body section select form-data like below attached image
Try with postman if that doesn't work try curl
curl -i -X POST -H "Content-Type: multipart/mixed" -F "fileInfoMap="name=xxx&age=24&location=yyy";type=application/x-www-form-urlencoded" -F "file=#somefile.zip" http://localhost:8080/upload

How to extract parameters from curl request in jersey servlet?

I am making a curl post restful request to my jersey servlet in the form
curl -i -X POST -d "debit_user_id=/custome/mobile_number:917827448775"http://localhost:8080/switch/apikongcall.do/transactions
I need to fetch the debit_user_id in my servlet, code for my Post method is
#POST
//#Path("/transactions")
//#Consumes(MediaType.APPLICATION_JSON)
public Response createTrackInJSON(#QueryParam("debit_user_id") String debit_user_id) {
//Log logger = null;
this.logger = LogFactory.getLog(getClass());
this.logger.info("Inside post method"+debit_user_id);
String response = debit_user_id;
//String response = "testParam is: " + recipient_id + "\n";
//String result = "Track saved : " + track;
return Response.status(200).entity(response).build();
But my debit_user_id is coming as null. Is it the correct way to make the curl restful request or the way I am extracting it in my servlet is wrong.
I am new to jax-rs. Thanks in advance for the help.
The -d option to curl passes in a url encoded form parameter. You have to change #QueryParam to #FormParam to make the given Curl command work. Also, just specify the parameter name as mobile_number without the pathing that you used in you curl command, like so:
curl -i -X POST -d "debit_user_id=mobile_number:917827448775" http://localhost:8080/switch/apikongcall.do/transactions
maps to
#POST
#Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public Response createTrackInJSON(#FormParam("mobile_number") String debit_user_id) {
...
}
If you do in fact want a query parameter, your curl command would need to change:
curl -i -X POST http://localhost:8080/switch/apikongcall.do/transactions?mobile_number=917827448775
For security reasons, it's probably better to keep the mobile number in the message body, so I'd use the FormParam instead of the QueryParam.

Jersey Test Equivalent to curl request

First trip into the Java web services world. Trying to write a test for a post request. The post looks like this in curl:
url -v -X POST -H 'Content-Type: application/json' -d '{"transaction_zips": ["78732"],"condition": "good"}' http://localhost:8080/PricingService/vin/1GTEC19J37E152026/usedValues
I've attempted:
#Test
public void testVinPricing200() {
int status = target.path("PricingService/vin/1GTEC19J37E152026/usedValues").request(MediaType.APPLICATION_JSON_TYPE).
post(Entity.entity("{\"transaction_zips\": [\"78732\"],\"condition\": \"good\"}", MediaType.APPLICATION_JSON)).getStatus();
assertEquals(200, status);
}
This results in:
Failed tests: testVinPricing200(com.comp.platform.PricingServiceTest): expected:<200> but was:<406>
So the question is simple, I'm obviously not posting correctly, what am I doing wrong?
The difference between your curl request and your junit test in your junit test you are requesting a response of type MediaType.APPLICATION_JSON_TYPE, but your webservice is not capable of responding via JSON.
Http Status code: 406
The resource identified by the request is only capable of generating response entities
which have content characteristics not acceptable according to the accept headers sent in
the request.

Get data in java when http request sent by curl command

Does anyone know how to get data in java when http request sent by curl command "--data"?
For example :
curl --data { Name : username , Gender : gender , Age : age } -X PUT http://localhost:8080/user/folder -v
I want to know how to get data { Name :username ,..... age } using curl command --data.
I use the method in REST Web service which is used jersey framework and java .
Since you PUT data when you use curl this way, all you need to do is to implement a PUT request handler. In theory at least :)
Something like
#PUT
#Path("/user/folder")
#Consumes("application/json")
public void receiveData(String data) {
......
}
edit: didn't see the -X PUT at first. you want a PUT handler not a POST handler.
