关于okhttp上传文件
老师讲的类已经被不用了，对于新的okhttp3.5.0，上传表单带图片怎么图片一直传布上去，也看了okhttp3.x的demo
public void doUpload(View view) {
File file = new File(Environment.getExternalStorageDirectory(), "2.jpg");
if (!file.exists()) {
L.e(file.getAbsolutePath() + "not exist!");
}
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("username", "xiaoqiang")
.addFormDataPart("password", "123")
.addFormDataPart("mPhoto", "2.jpg", RequestBody.create(MediaType.parse("image/jpeg"), file))
.build();
Request request = new Request.Builder()
.url(BaseUrl + "uploadInfo")
.post(requestBody)
.build();
executeRequest(request);
}这个是我写的，可是一直报错，在服务端图片接收不到，图片是按老师写的
