Question

我通过了邮递员的请求，并获得了成功的答复。现在，当我尝试使用Retrofit 2通过代码执行相同操作时，出现错误：com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $。

最初我收到以下错误： Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 1 path $，但在将.setLenient()添加到Gson builder之后，就解决了。

我知道，如果Model与响应不符，通常会发生这种情况。但是这一次我想我已经检查了所有复选框，但是仍然遇到错误。

模型

class LoginResponse(val access_token: String?, val token_type: String?, val user: UserResponse, val expires_at: String)

class UserResponse(
  val id: Long?,
  val name: String?,
  val email: String?,
  val created_at: String,
  val updated_at: String,
  val api_token: String
)

RestApiInterface

@POST(LOGIN)
fun login(@Body user: LoginRequest): Call<LoginResponse>

改造

@Provides
@Reusable
fun provideRetrofit(gson: Gson): Retrofit {

    val interceptor = HttpLoggingInterceptor()
    interceptor.level =
        if (BuildConfig.DEBUG) HttpLoggingInterceptor.Level.BODY else HttpLoggingInterceptor.Level.NONE


    val okBuilder = OkHttpClient.Builder()
    okBuilder.addInterceptor(interceptor)
    okBuilder.addInterceptor { chain ->
        val request = chain.request()
        val builder = request.newBuilder()
        chain.proceed(builder.build())
    }

    return Retrofit.Builder()
        .addConverterFactory(GsonConverterFactory.create(gson))
        .baseUrl(API_BASE_URL)
        .client(okBuilder.build())
        .build()
}

Gson

@Provides
fun providesGson(): Gson {
    return GsonBuilder().setLenient().create()
}

回复（邮递员）

{
"access_token": "eyJ0eX...",
"token_type": "Bearer",
"user": {
    "id": 1,
    "name": "Api",
    "email": ".......",
    "created_at": "2018-07-09 08:52:31",
    "updated_at": "2019-06-12 10:58:36",
    "api_token": "OVp5CuRDLQ92tiXobTJNuf4HASfU0xpiMoChVdbyL2OQspajmFDPAqrlCLHD"
},
"expires_at": "2020-06-19 17:30:31"

}
