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：
