Retrofit - 抛出异常java.lang.IllegalArgumentException:只允许一个编码注释

Question

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);

问题是当我试图将文件参数作为一个零件添加时,如果我只使用@Field它会给我带来错误,但是它很好但是在我添加@Part之后无法工作
- 是否有一种方法无法使用@Field和@part在Retrofit？
- 如果是,则告诉理由,如果没有告诉我正确的方法

我将非常感谢您的回答,并提前感谢您

您不能在单个方法上同时使用@FormUrlEncoded和@Multipart.HTTP请求只能有一个Content-Type,而且这两个都是内容类型.

@FormUrlEncoded (for android)| application/x-www-form-urlencoded(for web)

@Multipart(for android)| multipart/form-data(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 );

和这样的电话......

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 {
                    Toast.makeText(UploadActivity.this, "Sorry for inconvince server is down", Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onFailure(Call<Result> call, Throwable t) {
                progress.dismiss();
                Toast.makeText(UploadActivity.this, "Check your Internet connection", Toast.LENGTH_SHORT).show();
            }
        });
    }

注意: - 使用上面的示例进行文件POST,如果你卡在任何地方,请告诉我.

对于你的情况使用这样.....

    @Multipart
@POST("registration.php")
Call<Signup> getSignupResponse(@Part("email") RequestBody email,
                               @Part("lname") RequestBody lname,
                               @Part("fname") RequestBody fname,
                               @Part("password") RequestBody password,
                               @Part MultipartBody.Part filename);

并使用像这样的改装电话.....

 File file = new File(path);
    RequestBody emailRequest = RequestBody.create(MediaType.parse("text/plain"), email);
    RequestBody lnameRequest = RequestBody.create(MediaType.parse("text/plain"), lname);
    RequestBody fnameRequest = RequestBody.create(MediaType.parse("text/plain"), fname);
    RequestBody passwordRequest = RequestBody.create(MediaType.parse("text/plain"), password);

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



      Call<Signup> call = qikGrubApi.upload(emailRequest, lnameRequest ,fnameRequest , passwordRequest, filePart);

            call.enqueue(new Callback<Signup>() {
                @Override
                public void onResponse(Call<Signup> call, Response<Signup> 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 {
                        Toast.makeText(UploadActivity.this, "Sorry for inconvince server is down", Toast.LENGTH_SHORT).show();
                    }
                }

                @Override
                public void onFailure(Call<Signup> call, Throwable t) {
                    progress.dismiss();
                    Toast.makeText(UploadActivity.this, "Check your Internet connection", Toast.LENGTH_SHORT).show();
                }
            });
        }
