记一次访问http数据接口的爬坑经历,一般访问一个http接口。
无非就是这么几行代码:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("url"); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); System.IO.StreamReader sr = new StreamReader(response.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8"));//设置响应编码,乱码的话 Console.Write(sr.ReadToEnd()); sr.Close(); response.Close();
可是这次,死话乱码。PostMan下正常的。。在浏览器中直接访问,设置编码为utf-8b也是可以正常显示的。。用c#后台代码测试了各种编码都以无效,告终。。
查看响应头:
Content-Encoding gzip。。。。刚开始被我略过了。。后来搜乱码google到了博客园的博问。
更新代码如下:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("url"); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //先把响应流以gzip形式解码,然后再读取。结果success....... Stream stm = new GZipStream(response.GetResponseStream(),CompressionMode.Decompress); System.IO.StreamReader sr = new StreamReader(stm, System.Text.Encoding.GetEncoding("utf-8")); Console.Write(sr.ReadToEnd()); sr.Close(); response.Close();
