Android 改型-引发异常java.lang.IllegalArgumentException：只允许一个编码注释

大家好，这是我的示例代码

@FormUrlEncoded
@Multipart
@POST("registration.php")
Call<Signup> getSignupResponse(@Field("email") String email,
                               @Field("lname") String lname,
                               @Field("fname") String fname,
                               @Field("password") String password,
                               @Part("filename") File file);

@FormUrlEncoded
@多部分
@POST（“registration.php”）
调用getSignupResponse（@Field（“email”）字符串email，
@字段（“lname”）字符串lname，
@字段（“fname”）字符串fname，
@字段（“密码”）字符串密码，
@部分（“文件名”）文件）；

问题是，当我试图将文件参数作为一个部分添加时，如果我只使用@Field，它会抛出一个错误，但在我将@Part添加到其中后，它工作得很好，但不起作用
-是否无法在改造中同时使用@Field和@part？？
-如果是，请告诉我原因；如果不是，请告诉我正确的方法

我将感谢您的回答，并提前向您表示感谢

注：投票前在评论中告诉我一些建议

不能在单个方法上同时使用@FormUrlEncoded和@Multipart。 HTTP请求只能有一种内容类型，并且这两种类型都是 内容类型

@FormUrlEncoded（适用于android）应用程序/x-www-form-urlencoded（适用于web）

@Multipart（适用于android）多部分/表单数据（适用于web）

像这样使用

  @Multipart
    @POST("photos/upload")
    Call<Result> upload(@Part("Token") RequestBody token, @Part("Photo_Type") RequestBody type, @Part MultipartBody.Part  file );

String token="your string";

File file = new File(path);
RequestBody tokenRequest = RequestBody.create(MediaType.parse("text/plain"), token);
RequestBody type = RequestBody.create(MediaType.parse("text/plain"), true + "");

MultipartBody.Part filePart = MultipartBody.Part.createFormData("file", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));



  Call<Result> call = qikGrubApi.upload(tokenRequest, type, filePart);

        call.enqueue(new Callback<Result>() {
            @Override
            public void onResponse(Call<Result> call, Response<Result> response) {
                progress.dismiss();
                if (response.isSuccessful()) {
                    if (response.body().getSuccess()) {
                        nextPage(response.body().getMessage());
                    } else
                        Toast.makeText(UploadActivity.this, response.body().getMessage(), Toast.LENGTH_SHORT).show();
                } else {

删除

@FormUrlEncoded

注释…..@sushildlh如果我删除了@FormUrlEncoded，我会得到这个>>java.lang.IllegalArgumentException:@Field参数只能与表单编码一起使用。使用

@Part

而不是

@Field

。。你的意思是说我只需要为表单编码创建另一个api吗图像上传我无法上传和传递带有字符串参数的文件：（对？？您可以使用

RequestBody

变量传递并将字符串放入其中…在上面的示例中

tokenRequest

是

string

…谢谢您我得到了我想要的，非常感谢您宝贵的时间再次感谢：）
