com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期 BEGIN_OBJECT 但在第 1 行第 1 列路径 $ 处为 STRING

Question

我收到以下错误

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

还有其他一些解决方案，但 none 对我有用。大多数人似乎都在谈论必须将 Call<WordOfTheDay> 变成 Call<List<WordOfTheDay>>，但由于 json 不是无用的数组。我相信是 JSON，但不确定。

JSON

改造 2.0

        Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(MainActivity.BASE_URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    //Initial Async Network Call Test
    WordAPI apiService = retrofit.create(WordAPI.class);
    Call<WordOfTheDay> call = apiService.getWordOfTheDay();
    call.enqueue(new Callback<WordOfTheDay>() {

        @Override
        public void onResponse(Response<WordOfTheDay> response, Retrofit retrofit) {
            int statusCode = response.code();
            WordOfTheDay temp = response.body();
            Log.d("temp","t");
        }

        @Override
        public void onFailure(Throwable t) {
            t.printStackTrace();
        }
    });

界面

public interface WordAPI {

@GET("/words.json/wordOfTheDay?api_key=??")
Call<WordOfTheDay> getWordOfTheDay();

}

Answer 1

您可能在第一个 '{' 之前有不可见的字符？因为错误说第一个元素是字符串而不是对象，所以如果真实的 json 看起来像：@#${"id":...

Answer 2

和我一样的问题。终于找到了根本原因，请确保请求的URI是正确的。
