一个超长时间的http api 的 nginx 超时错误 java.io.IOException: unexpected end of stream on Connection

简介: 一个长时间的http api 的 nginx 超时错误 直接访问IP是OK的。但是经过了中间一台域名机子,配置了nginx (基本上所有的超时时间timeout配置项都配置了足够的时间)的proxy_pass到这个IP上。

一个长时间的http api 的 nginx 超时错误

直接访问IP是OK的。但是经过了中间一台域名机子,配置了nginx (基本上所有的超时时间timeout配置项都配置了足够的时间)的proxy_pass到这个IP上。

用浏览器方式http api , 等待之后可以正确返回response。

但是,用下面的Kotlin代码的这个get方法调用:


fun get(url: String): String? {
    var result: String? = ""
    val okhttp = OkHttpClient.Builder()
            .connectTimeout(10, TimeUnit.MINUTES)
            .readTimeout(10, TimeUnit.MINUTES)
            .writeTimeout(10, TimeUnit.MINUTES)
            .build()

    val request = Request.Builder()
            .url(url)
            .addHeader("Connection","close")
            .build()

    val call = okhttp.newCall(request)

    try {
        val response = call.execute()
        result = response.body()?.string()
        println(result)

    } catch (e: IOException) {
        e.printStackTrace()
    }

    return result
}

出错日志:

用下面的Kotlin代码getAsync函数调用:



fun getAsync(url: String) {
    val okhttp = OkHttpClient.Builder()
            .connectTimeout(10, TimeUnit.MINUTES)
            .readTimeout(10, TimeUnit.MINUTES)
            .writeTimeout(10, TimeUnit.MINUTES)
            .build()

    val request = Request.Builder()
            .url(url)
            .build()

    val call = okhttp.newCall(request)

    call.enqueue(object : Callback {
        override fun onFailure(call: Call, e: IOException) {
            println(e.message)
            e.printStackTrace()
        }

        override fun onResponse(call: Call, response: Response) {
            try {
                val result = response.body()?.string()
                println(result)
            } catch (e: IOException) {
                println("response = ${response}")
                e.printStackTrace()
            }
        }
    })

}



也是抛错:
