I am using Volley for my HTTP requests and I have an HTTP put URL which looks like below.
http://mycompany.com/favorite/{roomNumber}/count. I am using a JSON object request. How do I make the API work with the extra "/count" in the API? I am passing the parameter room number in the JSON object.
JSON Object request works fine with this type of URL "http://mycompany.com/favorite/{roomNumber}"
JSON Object request
JsonObjectRequest request = new JsonObjectRequest(METHOD_TYPE_PUT, url, jsonObjectParams, responseListener, errorListener)
Can somebody help me with passing the JSON object parameter in the middle of the URL
Thanks.
You can call the API dynamically like this,
private void getTheApiData(int roomNumber){
JsonObjectRequest request = new JsonObjectRequest(METHOD_TYPE_PUT,
"mycompany.com/favorite" + roomNumber + "/count",
jsonObjectParams, responseListener, errorListener)
}
and call the above API dynamically by the method when you get the new data every time like this.
getTheAPiData(20) //if room number is 20
let me know if you have any issue #Shravani

I have started using WebClient(org.springframework.web.reactive.function.client.WebClient) for calling rest services. I have 2 classes say Utility.java and ServiceImpl.java.
ServiceImpl.java is where I use WebClient. A post call I am making looks like -
ClientResponse response = webClient.post()
.uri(path)
.body(Mono.just(inputDTO),InputDTO.class)
.exchange()
.block();
(ClientResponse above is org.springframework.web.reactive.function.client.ClientResponse)
(I am using exchange instaed of retrive because I want headers as well as status code)
Now trying to convert this response into some DTO - ResponseDTO.
Mono<ResponseEntity<ResponseDTO>> mono = response.toEntity(ResponseDTO.class);
ResponseEntity<ResponseDTO> resEntity = mono.block();
ResponseDTO myObj = resEntity.getBody();
So myObj is an object of ResponseDTO class.
The issue is - when I perform the conversion of 'response into ResponseDTO.java' in my utility class, I get myObj = null. But if I do it in my ServiceImpl.java (just after calling post API), it returns the proper body (ResponseDTO object).
The same issue occurs even if I perform the conversion and post call operation in two different methods in the ServiceImpl.java.
Do I need to configure something here?
I figured out what was the issue.
After calling REST api, body in the response if flushed out after I read it from the response for the first time. I had a Sysout statement in service implementation class where I was reading the body content.
Recommendation: Read the body content only once and store it in a variable. Use it wherever required.
I intend to send my server response in the following format
Api Doc
I did the following
headersR.add("response_code", "OK");
headersR.add("cmd_code", "SET_FK_NAME");
headersR.add("trans_id", Long.toString(System.currentTimeMillis()/1000000));
JSONPObject map1 = new JSONPObject("fk_name", "jj");
return new ResponseEntity<>(map1, headersR, HttpStatus.OK);
I was getting a negative response from the other side so I checked Wireshark(Had a hard time logging my response body). And I got this in Wireshark.

The response body is Definitely not JSON.
How can I fix this?
The response body fk_name("jj") is not JSON, it's JSONP -- Browser would take the function name fk_name and try to execute it with "jj" as parameter.
The root cause is you are using JSONPObject, whose constructor accepts 2 parameters: a function name, and the data value. Not the expected JSON key and value.
To fix this issue and return {"fk_name":"jj"}, remove the JSONPObject stuff and use code as follow:
return new ResponseEntity<>("{\"fk_name\":\"jj\"}", headersR, HttpStatus.OK);
Using POSTMANto call an endpoint for example:
http://localhost/v1
Checking Request Method in the code using:
context.getRequest().getMethod()
No matter what I change request method in postman request, I always get the first request method I select let say GET.
When i change request to
http://localhost/v1/
It works and start sending correct request methods i select in POSTMAN
http://localhost/v1
I am expecting that when I call:
http://localhost/v1
or
http://localhost/v1/
It should behave same way.
Any explanation to point to the right direction would be appreciated
you need to redirect /v1 to /v1/ try like
#RequestMapping(value="/v1")
public ModelAndView redirectToPage() {
return new ModelAndView("redirect:/v1/");
}
I am trying to pass a URL as a input parameter to a ApiController from an Angular REST call. The URL comes as a query string (this is a Provider Hosted app in SharePoint, I need the URL to query SP FWIW).
Here is the method signature in the ApiController:
// GET: api/ProjectSite/5
public IEnumerable<ProjectSite> Get(string id)
{
return ProjectSite.GetAllProjectSites(id);
}
And here is where I am making the call in Angular:
var spUrl = "'" + getParameterByName("SPHostUrl") + "'";
var queryUrl = "/api/ProjectSite/" + encodeURIComponent(spUrl);
return $http.get(queryUrl);
This generates a GET request that looks like this:
https://localhost:12345/api/ProjectSite/https%3A%2F%2Fcompany.sharepoint.com%2Fsites%2Fsite_dev%2Fweb
When I do I get 'HTTP 400 (Bad Request)' back. If I stop on a break point in the Angular code and change the input param to a simple string (e.g. 'asdf') the REST call is made and I see the Api is called. If I do not change the string and put a breakpoint inside the Get Api method the breakpoint is not reached, indicating that the code is blowing up somewhere in the route engine.
What I don't get is, while its encoded, the string I am trying to pass in should still be treated as a string, right? I also tried changing the input to Uri but that doesn't appear to work (and Uri isn't listed as a supported input type, anyways).
Anyone know how to pass a URL as input parameter?
Have you tried calling it using a query string?
var queryUrl = "/api/ProjectSite?id=" + encodeURIComponent(spUrl);
I have a data object that gets sent as a POST request by an HTTPService object, but I want to be able to access the data object in the result handler. What is the best way to do this?
var token:AsyncToken = httpService.send();
token.yourPropertyName = yourObject;
AsyncToken is a dynamic object so you can add properties at runtime.
Then, in your result handler, you acces the token with :
event.token.yourPropertyName
