Retrofit2 上传图片等文件

普通写法:

//创建表单的普通字段
public static RequestBody createFormBody(String content) {

　　RequestBody body = RequestBody.create(MediaType.parse("multipart/form-data"), content);

　　return body;

}

//创建Multipart, fieldName为表单字段名

public static MultipartBody.Part createFilePart(String fieldName, File file) {

　　RequestBody requestFile = RequestBody.create(MediaType.parse("application/otcet-stream"), file);

　　MultipartBody.Part body = MultipartBody.Part.createFormData(fieldName, file.getName(), requestFile);

   return body;

}

//Service方法, 普通form表单使用RequestBody, 并且@Part注解要写表单字段名

//文件用MultipartBody.Part

@Multipart

@POST(API.VIDEO_MODULE_UPLOAD_VIDEO)

Call<Object> uploadImage(@Part MultipartBody.Part imagePicFile,

                         @Part MultipartBody.Part videoFile,

                         @Part("videoDescription") RequestBody desc,

                         @Part("videoPicWidth") RequestBody videoPicWidth,

                         @Part("videoPicHeight") RequestBody videoPicHeight);
   

//上传

getService(VideoService.class).uploadVideo(

                createFilePart("videoPicFile",new File(mCoverPath)),

                createFilePart("videoFile",new File(mPath)),

                createFormBody(etVideoDesc.getText().toString().trim()),

                createFormBody(width),

                createFormBody(height))

                .enqueue(new JsonResultCallback<Object>(context()) {

                    @Override

                    public void onSuccess(Call<Object> call, Object data) {

                        super.onSuccess(call, data);

                        //.....

                    }

                    @Override

                    public void onFinish(Call<Object> call) {

                        //...

                    }

                });
