httpClient: fail to respond

  org.apache.http.NoHttpResponseException: www.abc.com:port failed to respond

  这周在做一个功能,在调用外部接口的时候,莫名其妙的报这个错误。使用的类是很常见的HttpClient。网上看了其他文章,都是说什么设置“keepAlive”属性,试过了,没用;后面又怀疑服务方(www.abc.com),又证实服务方是ok的。之后又猜测是不是HttpClient的问题,就使用okHttp来调接口,使用okHttp确实是没 fail to resond的异常了,不过,有了新的异常 connect timed out

java.net.SocketTimeoutException: connect timed out

  最后还是经验老到的一个同事指出了错误:端口错了!网站www.abc.com提供了多个端口,写和读不是同一个端口,这个功能已经上线了,然而,我在上面开发新功能的时候才发现是有问题的,也就是之前那哥们根本就盲写代码!并且上线了!尼玛,也是无语了!
