我一直在用这段代码挣扎好几个小时。有人可以指导我在哪里我错过了？如果上传一个文件，它是成功的。当我将代码更改为多个文件时，它将会出错。 这里是我的okhttp JSONParser.java用okhttp3上传多个文件
public static JSONObject uploadImage(ArrayList<String> photoCaptions) {
try {
String photoUrl = photoCaptions.get(0);
String photoUrl2 = photoCaptions.get(1);
String photoUrl3 = photoCaptions.get(2);
File sourceFile = new File(photoUrl);
File sourceFile2 = new File(photoUrl2);
File sourceFile3 = new File(photoUrl3);
final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");
String filename = photoUrl.substring(photoUrl.lastIndexOf("/")+1);
String filename2 = photoUrl2.substring(photoUrl2.lastIndexOf("/")+1);
String filename3 = photoUrl2.substring(photoUrl2.lastIndexOf("/")+1);
Log.d("TAG", "File...::::" + sourceFile.getName() + " : "+ photoUrl + " - " + sourceFile.exists());
MultipartBody.Builder multipartBuilder = new MultipartBody.Builder()
.setType(MultipartBody.FORM);
RequestBody requestBody = multipartBuilder
.setType(MultipartBody.FORM)
.addFormDataPart("image1", filename, RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
.addFormDataPart("image2", filename2, RequestBody.create(MEDIA_TYPE_PNG, sourceFile2))
.addFormDataPart("image3", filename3, RequestBody.create(MEDIA_TYPE_PNG, sourceFile3))
.build();
Request request = new Request.Builder()
.url(URL_UPLOAD_IMAGE)
.post(requestBody)
.build();
OkHttpClient client = new OkHttpClient();
Response response = client.newCall(request).execute();
String res = response.body().string();
Log.e("TAG", "Error: " + res);
return new JSONObject(res);
} catch (UnknownHostException | UnsupportedEncodingException e) {
Log.e("TAG", "Error: " + e.getLocalizedMessage());
} catch (Exception e) {
Log.e("TAG", "Other Error: " + e.getLocalizedMessage());
}
return null;
}
以下是错误
