POST因改造而失败（连接超时），但与邮递员一起工作[关闭]

Question

已解决：愚蠢的错误，我有 https://foo.foo.com:433 而不是 https://foo.foo.com:443...

我已经实现了改造，我正在尝试发送一个带有 JSON 数据作为 JsonObject 的 POST 请求。它不工作，我得到一个失败的“连接超时”，但我可以通过邮递员毫无问题地发送一个 POST 请求。起初我以为是因为标题，我尝试过使用拦截器并使用@Header 而不是@Headers。感谢您的帮助。

API 接口

interface ApiEndpoints {
    @POST("/")
    @Headers("Content-Type: application/json")
    fun sendRequest(@Body json: PostModel): Call<ResponseModel>
} 

改造客户端

class ApiClient {
    val service = Retrofit.Builder()
        .baseUrl("https://foo.foo.com:433")
        .client(client) // Implement HttpLoggingInterceptor()
        .addConverterFactory(GsonConverterFactory.create())
        .build()
        .create(ApiEndpoints::class.java)
}    

API 调用

val test = ApiClient().service.sendRequest(
            PostModel("web",
                    "ggrojeomieje2",
                    105,
                    "signal",
                    1,
                    "signal",
                    Params())
)

test.enqueue(object : Callback<ResponseModel> {
        override fun onResponse(call: Call<ResponseModel>?, response: Response<ResponseModel>?) {
            println("response " + response?.body()?.params?.timestamp.toString())
        }

        override fun onFailure(call: Call<ResponseModel>?, t: Throwable?) {
            println("failure " + t?.message.toString())
        }
    }) 

模型

data class ResponseModel(val params: Params?)


data class PostModel(var transport: String? = null,
                     var userId: String? = null,
                     var moduleId: Int? = 0,
                     var moduleName: String? = null,
                     var moduleVersion: Int? = 0,
                     var operation: String? = null,
                     var params: Params?
)

data class Params(var timestamp: Unit? = null)

回应

{"params":{"timestamp":1.530346984546E9}} 

Answer 1

尝试在OkHttpClient中设置超时值。

val client = OkHttpClient.Builder()
    .connectTimeout(30, TimeUnit.SECONDS)
    .writeTimeout(30, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .build()

还可以尝试更改请求正文类型，例如 x-www-form-urlencoded 或 form-data 以及类似 @Headers({"content-type: application/json"}) 的标头

或

检查是否有任何与网络相关的问题，或者只是尝试一些简单的GET 方法也失败了。
