改装PUT不起作用

Question

我正在使用“ Discord API”开发一个Android应用程序。

首先，如果我在Postman中调用相同的API，则可以正常工作。 但是在我的Android应用程序中，它不起作用。

我要使用的API是这样的：“ https://discordapp.com/developers/docs/resources/guild#add-guild-member ”

我想使用“ Retrofit库”在Android应用程序中做同样的事情。

下面是界面。

    @PUT("guilds/{guildId}/members/{userId}")
    Call<RespUser> joinGuild(@Path("guildId") String guildId, @Path("userId") String userId, @Header("Authorization") String token, @Header("Content-Type") String contentType, @Body String body);

下面是工具：

    @Override
public void joinGuild(DUser dUser, String authorization) {
    Log.d(TAG, "[CHICKEN] joinGuild: " + dUser + ", " + authorization);

    Gson gson = new Gson();
    String body = gson.toJson(new DJoinBody(authorization, dUser.getUsername()));
    Log.d(TAG, "[CHICKEN] joinGuild - body: " + body);

    Call<RespUser> guildCall = mDiscordService.joinGuild(BuildConfig.DISCORD_GROUP_ID, dUser.getId(), BuildConfig.DISCORD_BOT_TOKEN, "application/json", body);

    Log.d(TAG, "[CHICKEN] joinGuild - request method: " + guildCall.request().method());
    Log.d(TAG, "[CHICKEN] joinGuild - request headers: " + guildCall.request().headers().toString());
    Log.d(TAG, "[CHICKEN] joinGuild - request body.contentType: " + guildCall.request().body().contentType().toString());
    Log.d(TAG, "[CHICKEN] joinGuild - request body.: " + guildCall.request().body().toString());
    Log.d(TAG, "[CHICKEN] joinGuild - request: " + guildCall.request().toString());

    guildCall.enqueue(new Callback<RespUser>() {
        @Override
        public void onResponse(Call<RespUser> call, Response<RespUser> response) {
            if (response.isSuccessful()) {
                RespUser result = response.body();
                Log.d(TAG, "[CHICKEN] joinGuild - result: " + result);
            } else {
                try {
                    Log.e(TAG, "[CHICKEN] joinGuild - failed: " + response.code() + ": " + response.errorBody().string());
                    Log.d(TAG, "[CHICKEN] joinGuild - failed: " + response.raw().toString());
                    Log.d(TAG, "[CHICKEN] joinGuild - failed: " + response.headers().toString());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

        @Override
        public void onFailure(Call<RespUser> call, Throwable t) {

        }
    });
}

错误是：

{"_misc": ["Only dictionaries may be used in a DictType"]}

你能告诉我我在做什么错吗？

我找到了解决方案。 我将“正文”参数的类型从“字符串”更改为“对象”。

之前的代码：

@PUT("guilds/{guildId}/members/{userId}")
Call<RespUser> joinGuild(@Path("guildId") String guildId, 
    @Path("userId") String userId, 
    @Header("Authorization") String token, 
    @Header("Content-Type") String contentType, 
    @Body String body);

代码后：

@Headers({"Content-Type: application/json"})
@PUT("guilds/{guildId}/members/{userId}")
Call<RespUser> joinGuild(@Path("guildId") String guildId, 
    @Path("userId") String userId, 
    @Header("Authorization") String token, 
    @Body DJoinBody joinBody);
