POST无法进行翻新（连接超时），但可以与Postman一起使用

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Retrofit，我正尝试将JSON数据作为JsonObject发送POST请求。它无法正常工作，并且出现“连接超时”失败，但是我可以通过Postman发送POST请求而没有问题。起初我以为是因为标头，所以我尝试使用Interceptor并使用@Header而不是@Headers。谢谢您的帮助。

从HttpLoggingInterceptor（）登录

Api界面

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通话

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)

回复

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

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()

还尝试更改请求主体类型，例如x-www-form-urlencoded或form-data和标头，例如@Headers({"content-type: application/json"})

或

检查是否存在与网络相关的问题，或者只是尝试一些简单的GET方法也失败了。
