未找到改造注释 #1

Question

我正在尝试使用 Retrofit 2.0 发出发布请求，该请求也有要发送的图像，但每次我尝试时都会收到错误消息，提示未找到改造注释..请帮助我解决这个问题...会非常谢天谢地.. 下面是我的代码 sn-p

我的改造界面

        //request body is used to attach file.
        RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"),imageFIle);

        //and request body and file name using multipart.
        MultipartBody.Part selectedIdproof = MultipartBody.Part.createFormData("id_proof", imageFIle.getName(),requestBody); //"image" is parameter for photo in API.

Answer 1

对于第一个参数，

检查这段代码

File file = new File(filePath);

RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);

MultipartBody.Part body = MultipartBody.Part.createFormData("upload",file.getName(), reqFile);

你有这个MediaType.parse("multipart/form-data") 试试上面的。你需要使用文件提供程序，为了安全地从你的应用程序向另一个应用程序提供文件，你需要配置你的应用程序以提供对文件的安全句柄，格式为的内容 URI。 Android FileProvider 组件根据您在 XML 中提供的规范为文件生成内容 URI。

为您的应用定义 FileProvider 需要在您的清单中添加一个条目。此条目指定用于生成内容 URI 的权限，以及指定您的应用可以共享的目录的 XML 文件的名称。

 String mCurrentPhotoPath;

 private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new  Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
    imageFileName,  /* prefix */
    ".jpg",         /* suffix */
    storageDir      /* directory */
);

// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;

}

然后调用该函数将文件公开给文件提供程序以获取路径。

    Uri photoURI = FileProvider.getUriForFile(this,
                                              "com.example.android.fileprovider", image /* return file*/);
