This may be easy one, but I am confused.
I am trying to do HTTP POST on a server using Android Restlet, and read the reply returned from the server.
I created form using:
Form form = new Form
form.add("msg" ,"This is my message");
Now, I have clientResource as follows:
ClientResource clientResource = new ClientResource("www.example.com/my-http-post-url/");
Now, I am doing HTTP Post as:
Representation response=null;
try{
response= clientResource.post(form.getWebRepresentation(null));
System.out.println("Got response !! , response : " + response.getText());
System.out.println( "Got Context: " + clientResource.getContext() );
System.out.println( "Got Response: " + clientResource.getResponse());
System.out.println( "Got Resonse Attribute : " + clientResource.getResponseAttributes() );
System.out.println( "Got Resonse Entity: " + clientResource.getResponseEntity() );
}catch(Exception e){
e.printStackTrace();
}
I found out that the code is going inside try, but its printing :
I/org.restlet( 493): Starting the default HTTP client
I/System.out( 493): Got response !! , response : null
I/System.out( 493): Got Context: null
I/System.out( 493): Got Response: HTTP/1.1 - OK (200) - OK
I/System.out( 493): Got Resonse Attribute : {org.restlet.http.headers=[(Date,Sun, 22 Jul 2012 22:14:03 GMT), (Server,WSGIServer/0.1 Python/2.7.1+), (Vary,Authorization), (Content-Type,application/json; charset=utf-8)]}
I/System.out( 493): Got Resonse Entity: [application/json,UTF-8]
I tried sniffing the data, to see if the server is replying or not, I am confident that server is sending the response content.
Can anyone tell me, how can I find out the response content send by the server?
You're using client-side support of Restlet the right way. The response content should be contained within the response representation...
The first step is to call your REST service outside Android to see the exact response content. Can you try to do this using restclient (http://code.google.com/p/rest-client/) or curl?

Try something like this:
I have something similar to this right now:
ClientResource clientResource = new ClientResource(url);
Request request = new Request(Method.POST, url);
clientResource.setRequest(request);
Form form = new Form();
form.set("foo", "barValue");
org.restlet.representation.Representation response = clientResource.post(form, MediaType.APPLICATION_JSON);
Representation responseEntity = clientResource.getResponseEntity();
JsonRepresentation jsonRepresentation = new JsonRepresentation(responseEntity);
JSONObject jsonObject = jsonRepresentation.getJsonObject();
String[] names = JSONObject.getNames(jsonObject);
if (jsonObject.has("errorString"))
{
String error = jsonObject.optString("errorString");
}

I'm trying to make a POST request with custom headers and json as string on body
Here's my code
HttpRequest request2 = HttpRequest.newBuilder()
.uri(URI.create(POSTS_API_URL))
.headers("accept", "text/plain; charset=UTF-8", "XF-Api-Key", "MYAPIKEY")
.POST(HttpRequest.BodyPublishers.ofString(json))
.build();
System.out.println(request2); //result : https://******.fr/api/auth/ POST
System.out.println(request2.headers()); //result : java.net.http.HttpHeaders#8e33ff08 { {accept=[text/plain; charset=UTF-8], XF-Api-Key=[MYAPIKEY]} }
HttpResponse<String> response2 = client.send(request2, HttpResponse.BodyHandlers.ofString());
// print status code
System.out.println(response2.statusCode()); //400
// print json code
System.out.println(json); //{"login":"LunaLune","password":"***********"}
// print response body
System.out.println(response2.body()); //mandatory input missing : login, password
And my json String
String json = "{" +
"\"login\":\"LunaLune\"," +
"\"password\":\"*********\"" +
"}";
But when I print the request I get : https://*******.fr/api/auth/ POST
the POST request is empty
I googled many forums, code examples ect... but I see that my code where correct according many examples I seen.
So if someone know what is my problem ?
Thanks in advance !
You need to set "Content-Type" as "application/json" in the request header.
See: Which JSON content type do I use?
API Headers have two parameter Content-Type=application/json and also accesstoken = "some_token"
I trying to automate the API using Rest assured but not successful.
Below is the code
RestAssured.baseURI = prop.getProperty("serviceurl1");
//2. define the http request:
RequestSpecification httpRequest = RestAssured.given()
.filter(new ResponseLoggingFilter())
.filter(new RequestLoggingFilter());
JSONObject requestParams = new JSONObject();
requestParams.put("longitude", eLongitude);
requestParams.put("latitude", eLaititude);
requestParams.put("country", eCity);
httpRequest.headers("Content-Type", "application/json");
httpRequest.headers("accesstoken", "some_token.");
httpRequest.body(requestParams.toJSONString());
int statusCode = response.getStatusCode();
System.out.println("the status code is: "+ statusCode);
Assert.assertEquals(statusCode, TestUtil.RESPONSE_CODE_200);
System.out.println("the status line is: "+ response.getStatusLine());
//6. get the headers:
Headers headers = response.getHeaders();
System.out.println(headers);
String contentType = response.getHeader("Content-Type");
System.out.println("the value of content-type header is: "+ contentType);
String contentLength = response.getHeader("Content-Length");
System.out.println("the value of Content-Length header is: "+ contentLength);
Getting error message as "Provide Application Token" and 404 error code display.
Your httpRequest.headers("accesstoken", "kggkgkgkgketdfgxgcccvcdftfty."); is wrong. It should be:
httpRequest.headers("Authorization", "Bearer "+token);
can you try this once
Response resp = given().when().contentType(ContentType.JSON).header("accesstoken", "token").body(body).put("url");
You can pass the HashMap as body
These are the issues I can think of
This might be an internal API and it is expecting "Provide Application Token" and not the "accesstoken"
The error code you are getting is 404. So either the service is down or the URL you are using is not correct.
Hope this helps :)
I'm trying to create $http get request to fetch some json data generated by my web service, but it returns null error. However, the $http request works fine when I use this sample url instead (it returns json string too)
This is my angular code :
angular.module('ionicApp', ['ionic'])
.controller('ListCtrl', function ($scope, $http) {
$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";
$http.get("http://localhost:8080/InventoryCtrl_Service/webresources/IVC_Service/GetUserList")
.then(function(response) {
console.log("success ");
},
function(response) {
console.log("Error : " + response.data + " Status : " + response.status);
}
});
This is my web service code :
#GET
#Path("/GetUserList")
#Produces("application/json")
public Response GetUserList() throws SQLException {
net.sf.json.JSONObject json = new net.sf.json.JSONObject();
JSONObject obj1 = new JSONObject();
JSONObject obj2 = new JSONObject();
JSONObject outerObject = new JSONObject();
JSONArray arr = new JSONArray();
obj1.put("Name", "Sara");
obj2.put("Name","David");
arr.add(obj1);
arr.add(obj2);
outerObject.put("records", arr);
return Response.status(200).entity(outerObject.toString()).build();
}
When I run the above code, it returns json string like this :
{"records":[{"Name":"Sara"},{"Name":"David"}]}
The console log returns this :
Error : null Status : 0
What is the meaning of the null error? Or is there anything wrong with how I return the json string?
Try using JSON_STRINGIFY, this will convert your incoming data into String format.
console.log(JSON_STRINGIFY(response.data));
TO verify what data your web service is returning, you can always check it by hitting your web service via postman.
I managed to solve this by adding CORS (Access-Control-Allow-Origin) to the response header, based on another SO answer. There's no problem with my angular code, it's just that I need to modify my web service code to enable the CORS. So I just modified the part where it returns data to become like this :
return Response.status(200).entity(outerObject.toString()).header("Access-Control-Allow-Origin", "*").build();
I'm sending a http post request from javascript, with some json data.
Javascript
var data = {text : "I neeed to store this string in database"}
var xhr= new XMLHttpRequest();
xhr.open("POST","http://localhost:9000/postJson" , true);
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
xhr.send(data);
xhr.setRequestHeader("Connection", "close");
//Also, I've tried a jquery POST
//$.post('postJson', {'data=' : JSON.stringify(data)});
//But this doesn't make a request at all. What am I messing up here?
Route
POST /postJson controllers.Application.postJson()
Controller
public static Result postJson(){
//What should I write here to get the data
//I've tried the below but values is showing null
RequestBody rb=request().body();
final Map<String,String[]> values=rb.asFormUrlEncoded();
}
What is the way to parse the POST request body?
Much thanks!
Retreive the request body directly as JSON... no need to complicate your life.
public static Result postJson() {
JsonNode rb = request().body().asJson();
//manipulate the result
String textForDBInsertion = rb.get("text").asText(); //retreives the value for the text key as String
Logger.debug("text for insertion: " + textForDBInsertion
+ "JSON from request: " + rb);
return ok(rb);
}
Also, I recommend you use the AdvancedRestClient Chrome plugin for testing. This way you can eliminate from the equation client-side code errors.
Cheers!
I want to add post to my blog using Blogger API. I successfully got rights to use Blogger API and activated them in Google API console. I used this tutorial to obtain access_token. I found this question , so before ever request I obtain new request_token.
When I make first request to add post, I got en error: 401 "message": "Invalid Credentials", "location": "Authorization".
When I make second request to add post with new token, I got error: 403 "message": "Daily Limit Exceeded. Please sign up"
Code for my request is:
final JSONObject obj = new JSONObject();
obj.put("id", mUserID);
final JSONObject requestBody = new JSONObject();
requestBody.put("kind", "blogger#post");
requestBody.put("blog", obj);
requestBody.put("title", msg[0]);
requestBody.put("content", msg[0] + " " + msg[1]);
final HttpPost request = new HttpPost("https://www.googleapis.com/blogger/v3/blogs/" + mUserID + "/posts");
request.addHeader("Authorization", "Bearer " + mToken);
request.addHeader("Content-Type", "application/json");
request.setEntity(new StringEntity(requestBody.toString()));
final HttpResponse response = mHttpClient.execute(request);
final HttpEntity ent = response.getEntity();
Log.i(SocialPoster.LOG, EntityUtils.toString(ent));
ent.consumeContent();
UPDATE
Solution was found: simply adding "?key={MY_API_KEY}" to request's URL solved the problem
The Tutorial site you linked states
"The API Key is mandatory as it identifies your application and therefore allows the API to deduct quota and use the quota rules defined for your project. You need to specify the API Key on your Tasks service Object."
useTasksAPI(String accessToken) {
// Setting up the Tasks API Service
HttpTransport transport = AndroidHttp.newCompatibleTransport();
AccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(accessToken);
Tasks service = new Tasks(transport, accessProtectedResource, new JacksonFactory());
service.accessKey = INSERT_YOUR_API_KEY;
service.setApplicationName("Google-TasksSample/1.0");
// TODO: now use the service to query the Tasks API
}
Sounds to me like you are missing the API key, using it wrong, misplaced it in your code or supplied it to the service in the wrong way.
I haven't looked over the code here, but this is Google's sample code for what you are trying to do. Test your API key with this code.
