I am trying to upload an image file in the folder from android to asp.net(Web Service- .asmx file) using retrofit.
I have created the web method for that and that web method is working appropriately and I tested on postman also.
But when I tried to upload from android then it displays the "500 Internal Server Error"
**Web Method (ASP.NET .asmx file)**
---------------------------------------
[WebMethod]
public void UploadImage_http()
{
var request = HttpContext.Current.Request;
var photo = request.Files["photo"];
photo.SaveAs(HttpContext.Current.Server.MapPath("images/thumbnail/"+photo.FileName));
JavaScriptSerializer js = new JavaScriptSerializer();
Feed feed = new Feed();
feed.err = false;
feed.err_message = "inserted success";
Context.Response.Write(js.Serialize(feed));
}
Android Side Code
------------------------------------------
API Interface
@Multipart
@POST("/FeedAPI.asmx/UploadImage_http")
public void upload(@Part("photo") MultipartBody.Part photo, Callback callback);
API Call
public void btnSelectSave(View view)
{
File file = new File(selectedImagePath);
// selectedImagePath contains the path of the image.
Toast.makeText(this, file.getName(), Toast.LENGTH_SHORT).show();
RequestBody photoContent = RequestBody.create(MediaType.parse("multipart/form-data"),file);
MultipartBody.Part photo = MultipartBody.Part.createFormData("photo",file.getName(),photoContent);
Log.e("DATA_ photos", ""+photo);
retrofitService.getService().upload(photo, new Callback() {
@Override
public void success(Feed feed, Response response) {
Toast.makeText(SharePostActivity.this, feed.getErr_message(), Toast.LENGTH_SHORT).show();
}
@Override
public void failure(RetrofitError error) {
Toast.makeText(SharePostActivity.this, error.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
Below Method use to get the path and value were store in **selectedImagePath**
public String getRealPathFromURI(Uri contentUri)
{
String[] proj = {MediaStore.Images.Media.DATA};
CursorLoader loader = new CursorLoader(getApplicationContext(),contentUri,proj,null,null,null);
Cursor cursor = loader.loadInBackground();
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String result = cursor.getString(column_index);
cursor.close();
return result;
}
Error Occurs:
