Android Retrofit 上传带文字的图片到PHP服务器

Question

我正在尝试创建一个系统，我可以在其中上传个人资料信息，例如姓名、电子邮件、密码和个人资料图片，用户可以在其中从图库或相机中选择图片。我正在尝试将 Retrofit 与 PHP 服务器和 MySQL 数据库一起使用。

问题是，我的代码只能处理图像或文本（名称、电子邮件、密码），我似乎无法让它同时处理这两者：

这是我的代码：接口类

 @POST("addProfile.php")
@FormUrlEncoded
Call<ServerResponse> addProfile(
        @Field("name") String name,
        @Field("email") String email,
        @Field("password") String password,
        @Field("picTitle") String picTitle,
        @Part MultipartBody.Part picFile

);

AppConfig 类：

public static Retrofit retrofit = null;
public static Retrofit getClient() {
    if (retrofit == null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}

uploadToPHPServer 方法：

private void uploadToServer(String name, String email, String password,String picTitle) {

    File file = new File(postPath);
    RequestBody requestBody = RequestBody.create(
            MediaType.parse("*/*")
            , file);

    MultipartBody.Part fileToSend = MultipartBody.Part.createFormData("picPath", file.getName(), requestBody);
    //picTitle = file.getName();

    //making api call
    ApiConfig api = AppConfig.getClient().create(ApiConfig.class);
    Call<ServerResponse> addingProfile = api.addProfile(name, email, password, picTitle, fileToSend);

    addingProfile.enqueue(new Callback<ServerResponse>() {
        @Override
        public void onResponse(Call<ServerResponse> call, Response<ServerResponse> response) {

            if(response.isSuccessful()){

                Toast.makeText(CaptureDetails.this,"Profile upload successful.", Toast.LENGTH_LONG).show();

            }else{
                Toast.makeText(CaptureDetails.this,response.body().getMessage(),Toast.LENGTH_LONG).show();
            }

        }

        @Override
        public void onFailure(Call<ServerResponse> call, Throwable t) {
            Toast.makeText(CaptureDetails.this,t.getLocalizedMessage(),Toast.LENGTH_SHORT).show();

        }
    });


}

我在尝试上传时收到以下错误：

我得到了@Part parameters can only be used with multipart encoding. 部分，但是如果我尝试更改它，我可以将@MultiPart 注释添加到接口类中，反之亦然。

我正在关注教程 here 和 here，但遇到了困难……我似乎在 Stack 上找不到教程或类似问题。

非常感谢您提供的任何帮助或指导。提前致谢

试试这个代码，错误是你尝试使用FormurlEncoded

@POST("addProfile.php")
@Multipart
Call<ServerResponse> addProfile(
    @Part ("name") String name,
    @Part ("email") String email,
    @Part ("password") String password,
    @Part ("picTitle") String picTitle,
    @Part MultipartBody.Part picFile
);
