Im finishing this project which is using okhttp for communication with a webservice.
All is going fine for regular GETs and POSTs, but I'm not being able to properly upload a file.
The okhttp docs are very lacking on these subjects and everything I found here or anywhere don't seem to work in my case.
It's supposed to be simple: I have to send both the file and some string values. But I can't figured out how to do it.
Following the some samples I found, I first tried this:
RequestBody requestBody = new MultipartBuilder().type(MultipartBuilder.FORM)
.addFormDataPart("group", getGroup())
.addFormDataPart("type", getType())
.addFormDataPart("entity", Integer.toString(getEntity()))
.addFormDataPart("reference", Integer.toString(getReference()))
.addPart(Headers.of("Content-Disposition", "form-data; name=\"task_file\""), RequestBody.create(MediaType.parse("image/png"), getFile()))
.build();
It gives me a "400 bad request" error.
So I tried this from the okhttp recipes:
RequestBody requestBody = new MultipartBuilder().type(MultipartBuilder.FORM)
.addPart(Headers.of("Content-Disposition", "form-data; name=\"group\""), RequestBody.create(null, getGroup()))
.addPart(Headers.of("Content-Disposition", "form-data; name=\"type\""), RequestBody.create(null, getType()))
.addPart(Headers.of("Content-Disposition", "form-data; name=\"entity\""), RequestBody.create(null, Integer.toString(getEntity())))
.addPart(Headers.of("Content-Disposition", "form-data; name=\"reference\""), RequestBody.create(null, Integer.toString(getReference())))
.addPart(Headers.of("Content-Disposition", "form-data; name=\"task_file\""), RequestBody.create(MediaType.parse("image/png"), getFile()))
.build();
Same result.
Don't know what else to try or what look into to debug this.
The request is done with this code:
// adds the required authentication token
Request request = new Request.Builder().url(getURL()).addHeader("X-Auth-Token", getUser().getToken().toString()).post(requestBody).build();
Response response = client.newCall(request).execute();
But Im pretty sure that the problem is how Im building the request body.
What am I doing wrong?
EDIT: "getFile()" above returns the a File object, by the way. The rest of the parameters are all strings and ints.
I found answer to my own question a bit after initial post.
I´ll leave it here, because it can be useful to others, given that there is such a few okhttp upload examples around:
RequestBody requestBody = new MultipartBuilder().type(MultipartBuilder.FORM)
.addFormDataPart("group", getGroup())
.addFormDataPart("type", getType())
.addFormDataPart("entity", Integer.toString(getEntity()))
.addFormDataPart("reference", Integer.toString(getReference()))
.addFormDataPart("task_file", "file.png", RequestBody.create(MediaType.parse("image/png"), getFile()))
.build();
There is no reason to use "addPart" with "Headers.of" etc like in the recipes, addFormDataPart does the trick.
And for the file field itself, it takes 3 arguments: name, filename and then the file body. That's it.
I just changed addFormDataPart
instead addPart
and Finally solved My Problem Using following code:
/**
* Upload Image
*
* @param memberId
* @param sourceImageFile
* @return
*/
public static JSONObject uploadImage(String memberId, String sourceImageFile) {
try {
File sourceFile = new File(sourceImageFile);
Log.d(TAG, "File...::::" + sourceFile + " : " + sourceFile.exists());
final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addFormDataPart("member_id", memberId)
.addFormDataPart("file", "profile.png", RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
.build();
Request request = new Request.Builder()
.url(URL_UPLOAD_IMAGE)
.post(requestBody)
.build();
OkHttpClient client = new OkHttpClient();
Response response = client.newCall(request).execute();
return new JSONObject(response.body().string());
} catch (UnknownHostException | UnsupportedEncodingException e) {
Log.e(TAG, "Error: " + e.getLocalizedMessage());
} catch (Exception e) {
Log.e(TAG, "Other Error: " + e.getLocalizedMessage());
}
return null;
}
in OKHTTP 3+ use this AsyncTask
SignupWithImageTask
public class SignupWithImageTask extends AsyncTask<String, Integer, String> {
ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog = new ProgressDialog(SignupActivity.this);
progressDialog.setMessage("Please Wait....");
progressDialog.show();
}
@Override
protected String doInBackground(String... str) {
String res = null;
try {
// String ImagePath = str[0];
String name = str[0], email = str[1], dob = str[2], IMEI = str[3], phone = str[4], ImagePath = str[5];
File sourceFile = new File(ImagePath);
Log.d("TAG", "File...::::" + sourceFile + " : " + sourceFile.exists());
final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");
String filename = ImagePath.substring(ImagePath.lastIndexOf("/") + 1);
/**
* OKHTTP2
*/
// RequestBody requestBody = new MultipartBuilder()
// .type(MultipartBuilder.FORM)
// .addFormDataPart("member_id", memberId)
// .addFormDataPart("file", "profile.png", RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
// .build();
/**
* OKHTTP3
*/
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("image", filename, RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
.addFormDataPart("result", "my_image")
.addFormDataPart("name", name)
.addFormDataPart("email", email)
.addFormDataPart("dob", dob)
.addFormDataPart("IMEI", IMEI)
.addFormDataPart("phone", phone)
.build();
Request request = new Request.Builder()
.url(BASE_URL + "signup")
.post(requestBody)
.build();
OkHttpClient client = new OkHttpClient();
okhttp3.Response response = client.newCall(request).execute();
res = response.body().string();
Log.e("TAG", "Response : " + res);
return res;
} catch (UnknownHostException | UnsupportedEncodingException e) {
Log.e("TAG", "Error: " + e.getLocalizedMessage());
} catch (Exception e) {
Log.e("TAG", "Other Error: " + e.getLocalizedMessage());
}
return res;
}
@Override
protected void onPostExecute(String response) {
super.onPostExecute(response);
if (progressDialog != null)
progressDialog.dismiss();
if (response != null) {
try {
JSONObject jsonObject = new JSONObject(response);
if (jsonObject.getString("message").equals("success")) {
JSONObject jsonObject1 = jsonObject.getJSONObject("data");
SharedPreferences settings = getSharedPreferences("preference", 0); // 0 - for private mode
SharedPreferences.Editor editor = settings.edit();
editor.putString("name", jsonObject1.getString("name"));
editor.putString("userid", jsonObject1.getString("id"));
editor.putBoolean("hasLoggedIn", true);
editor.apply();
new UploadContactTask().execute();
startActivity(new Intent(SignupActivity.this, MainActivity.class));
} else {
Toast.makeText(SignupActivity.this, "" + jsonObject.getString("message"), Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Toast.makeText(SignupActivity.this, "Something Went Wrong", Toast.LENGTH_SHORT).show();
}
}
