I am using Retrofit2 with OkHttp on Android for HTTP request. Here I am doing a POST request with document upload. I ran into error below:
D/OkHttp: <-- 500 Server Error http://api.drivewealth.io/v1/documents (4289ms) D/OkHttp: Date: Tue, 11 Apr 2017 03:29:48 GMT D/OkHttp: Cache-Control: must-revalidate,no-cache,no-store D/OkHttp: Content-Type: text/html; charset=ISO-8859-1 D/OkHttp: Server: Jetty(9.2.17.v20160517) D/OkHttp: Content-Length: 9323 D/OkHttp: Connection: keep-alive D/OkHttp: <html> D/OkHttp: <head> D/OkHttp: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> D/OkHttp: <title>Error 500 Server Error</title> D/OkHttp: </head> D/OkHttp: <body><h2>HTTP ERROR 500</h2> D/OkHttp: <p>Problem accessing /v1/documents.

The API server requires this format for the HTTP POST multipart request:
My code snippet as below:
1) create Retrofit Handler class:
Interceptor headerInterceptor = new Interceptor() { @Override public okhttp3.Response intercept(Interceptor.Chain chain) throws IOException { Request original = chain.request(); String sessionKey = JStockApplication.instance().getTradingOptions().getSessionKey(); okhttp3.Request request = original.newBuilder() //.header("Accept", "application/json") .header("Content-Type", "multipart/form-data") .header("x-mysolomeo-session-key", sessionKey) .method(original.method(), original.body()) .build(); return chain.proceed(request); } }; OkHttpClient.Builder httpClient = new OkHttpClient.Builder(); // add static common headers httpClient.addInterceptor(headerInterceptor); // add Logging for development, Log Level: NONE, BASIC, HEADERS, BODY HttpLoggingInterceptor logInterceptor = new HttpLoggingInterceptor() .setLevel(HttpLoggingInterceptor.Level.BODY); httpClient.addInterceptor(logInterceptor); Retrofit.Builder builder = new Retrofit.Builder() .baseUrl("http://api.drivewealth.io/v1/") .addConverterFactory(GsonConverterFactory.create()) .client(httpClient.build()); Retrofit retrofit = builder.build(); DriveWealthApi api = retrofit.create(DriveWealthApi.class); 2) Interface class for Retrofit method:
import okhttp3.MultipartBody; import okhttp3.RequestBody; import okhttp3.ResponseBody; import retrofit2.Call; import retrofit2.http.Body; import retrofit2.http.Multipart; import retrofit2.http.POST; import retrofit2.http.Part; public interface DriveWealthApi { @Multipart @POST("documents") Call<ResponseBody> addDocument( @Part("token") RequestBody token, @Part("documentType") RequestBody documentType, @Part MultipartBody.Part file); } 3) In my Fragment Class, the POST request is invoked in onCreate():
public class AddDocumentTaskFragment extends Fragment implements Callback<ResponseBody> { @Override public void onCreate(Bundle savedInstanceState) { ........ ........ Bundle bundle = this.getArguments(); String userID = bundle.getString(INTENT_EXTRA_USER_ID); String docType = bundle.getString(INTENT_EXTRA_DOCUMENT_TYPE); String fileUri = bundle.getString(INTENT_EXTRA_FILE_URI); Uri uri = Uri.parse(fileUri); String filePath = MyUtils.getPath(this.getActivity(), uri); if (filePath == null || filePath.isEmpty()) { return; } final File myFile = new File(filePath); MediaType mediaType = MediaType.parse(getActivity().getContentResolver().getType(uri)); if (myFile == null) { return; } // create RequestBody instance from file RequestBody requestFile = RequestBody.create(mediaType, myFile); // MultipartBody.Part is used to send also the actual file name MultipartBody.Part fileBody = MultipartBody.Part.createFormData("documentImage", myFile.getName(), requestFile); // add another part within the multipart request RequestBody tokenBody = RequestBody.create(okhttp3.MultipartBody.FORM, userID); RequestBody docTypeBody = RequestBody.create(okhttp3.MultipartBody.FORM, docType); // params: token, documentType, file this.call = driveWealthApi.addDocument(tokenBody, docTypeBody, fileBody); this.call.enqueue(this); } @Override public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) { ..... } @Override public void onFailure(Call<ResponseBody> call, Throwable t) { ...... } Any idea what went wrong here? Thanks!
