Cat Api：给定标头 api 键时的 SocketTimeout

Question

我正在用这个 api(https://docs.thecatapi.com/api-reference/images/images-search) 测试改造

只有两个类

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)


        Toast.makeText(this, "Calling API", Toast.LENGTH_LONG).show()
        GlobalScope.launch{
            val result = CatApiService.create().getCats(50,5,100,"json", "RANDOM")
            Log.i("My tag", "Success: retrieved size ${result.size}")
        }
    }
}

interface CatApiService {

    @GET("search/")
    suspend fun getCats(
        @Query("size") size: Int,
        @Query("page") page: Int,
        @Query("limit") limit: Int,
        @Query("format") format: String,
        @Query("order") order: String
    ): List<CatApiResponse>

    companion object {
        private const val BASE_URL = "https://api.thecatapi.com/v1/images/"

        fun create(): CatApiService {
            val client = OkHttpClient.Builder()
                .connectTimeout(10, TimeUnit.DAYS)
                 //add header to every request
                .addInterceptor(Interceptor { chain ->
                    val request = chain.request().newBuilder()
                        .addHeader("x-api-key", "{my api key}")  // <-- cause Timeout problem
                        .build()
                    return@Interceptor chain.proceed(request)
                })
                .build()
            return Retrofit.Builder()
                .baseUrl(BASE_URL)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build()
                .create(CatApiService::class.java)
        }
    }

当我在标头中传入 x-api-key 时遇到此异常

我在邮递员上进行了测试，所以 api 工作，我的 api 密钥也工作，我还检查了我在设备上启用了互联网。如果未放入标头，则 api 正确返回响应。 我想知道我是否没有正确设置改造？？

附上一个示例项目来演示问题。运行并等待 10 秒崩溃。

找到解决方法，增加 okhttpclient 中的读取超时

        val client = OkHttpClient.Builder()

                .readTimeout(60, TimeUnit.SECONDS) // this line fix the problem
                 //add header to every request
                .addInterceptor(Interceptor { chain ->
                    val request = chain.request().newBuilder()
                        .addHeader("x-api-key", "api-key")
                        .build()
                    return@Interceptor chain.proceed(request)
                })
                .build()
            return Retrofit.Builder()
                .baseUrl(BASE_URL)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build()
                .create(CatApiService::class.java)
        }
