Okhttp图像文件是一个空数组

Question

I am sending an image and associated data from my Android app to my laravel php backend

final MediaType JPEG = MediaType.parse("image/JPEG; charset=utf-8");

RequestBody body = new MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("filename", image.getFilename())
            .addFormDataPart("hash", image.getHash())
            .addFormDataPart("job_id", Integer.toString(image.getJobId()))
            .addFormDataPart("team", Integer.toString(image.getTeam()))
            .addFormDataPart("type", image.getType())
            .addFormDataPart("image_file", image.getFilename(), RequestBody.create(JPEG, imagefile)).build();

    Request request = new Request.Builder()
            .url(url)
            .post(body)
            .build();

    Response response = client.newCall(request).execute();

The backend php looks like this

public function updateJobImage(array $request_data){
    var_dump($request_data);

    $toInsertImage = [
        'job_id'    => $request_data['job_id'],
        'type'      => $request_data['type'],
        'filename'  => $request_data['filename'],
        'team'      => $request_data['team'],
        'hash'      => $request_data['hash']
    ];

    $filepath = '/schedule_images/' . $request_data['hash'] . "/" . $request_data['filename'];

    Storage::disk('s3_upload')->put($filepath, file_get_contents($request_data['image_file']));

I can get all the job_id/type/filename/team/hash data perfectly fine but the image_file is an empty array. How do I handle getting the image file on the php side

Please also check that image.getfilename() exist or not

          final MediaType MEDIA_TYPE = new image.getfilename().endsWith("jpg") ?
                  MediaType.parse("image/png") : 
MediaType.parse("image/jpeg");


          RequestBody requestBody = new MultipartBuilder()
                  .type(MultipartBuilder.FORM)
                  .addFormDataPart("image_file", System.currentTimeMillis()+"profile.jpg", RequestBody.create(MEDIA_TYPE, image.getfilename()))

                  .build();

          Request request = new Request.Builder()
                  .post(requestBody)
                  .url(url)
                  .build();
