【问题描述】：
我正在开发一个应用程序，我想从图库或相机中获取图像，然后使用 multipart 将其发送到服务器。我可以将图片从画廊发送到服务器，但是当我尝试从相机发送图像时，它显示我失败了。
// 相同的代码
//打开相机的代码
private void cameraIntent() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}
//关于活动结果
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CAMERA) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg");
Log.d("TAG", "onActivityResult: "+Uri.fromFile(destination));
filePath = destination.toString();
if (filePath != null) {
try {
execMultipartPost();
} catch (Exception e) {
e.printStackTrace();
}
} else {
Toast.makeText(getActivity(), "Image not capturd!", Toast.LENGTH_LONG).show();
}
}
// 发送到服务器代码
private void execMultipartPost() throws Exception {
File file = new File(filePath);
String contentType = file.toURL().openConnection().getContentType();
Log.d("TAG", "file new path: " + file.getPath());
Log.d("TAG", "contentType: " + contentType);
RequestBody fileBody = RequestBody.create(MediaType.parse(contentType), file);
final String filename = "file_" + System.currentTimeMillis() / 1000L;
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("date", "21-09-2017")
.addFormDataPart("time", "11.56")
.addFormDataPart("description", "hello")
.addFormDataPart("image", filename + ".jpg", fileBody)
.build();
Log.d("TAG", "execMultipartPost: "+requestBody);
okhttp3.Request request = new okhttp3.Request.Builder()
.url("http://myexample/api/user/lets_send")
.post(requestBody)
.build();
OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, final IOException e) {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getActivity(), "nah", Toast.LENGTH_SHORT).show();
}
});
}
@Override
public void onResponse(Call call, final okhttp3.Response response) throws IOException {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
try {
Log.d("TAG", "response of image: " + response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
});
}
