标签:private 出错 amp ica 方法 amr pre util finally GET方法: 注意:url中的中文,要先用HttpUtility.UrlEncode("内容",编码) 用服务器接收的编码,编码一下。 POST方法: 出现中文乱码问题,服务器返回的contentType编码类型 和 你接受数据的编码类型 不一样造成的 C# HttpRequest 中文编码问题 标签:private 出错 amp ica 方法 amr pre util finally 原文地址:https://www.cnblogs.com/zquan/p/9750143.htmlpublic string DoWebRequest(string url)

}
webResponse.Close();//关闭web响应流
}
}
return responseStr;
}
private string DoWebRequestByPost(string url, string param)
{
HttpWebResponse webResponse = null;
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
//使用post方式提交
webRequest.Method = "POST";
string responseStr = null;
webRequest.Timeout = 50000;
//要post的字节数组
byte[] postBytes = encoding.GetBytes(param);
webRequest.ContentType = "application/x-www-form-urlencoded;";
webRequest.ContentLength = postBytes.Length;
using (Stream reqStream = webRequest.GetRequestStream())
{
reqStream.Write(postBytes, 0, postBytes.Length);
}
try

//尝试获得要请求的URL的返回消息
webResponse = (HttpWebResponse)webRequest.GetResponse();
}
catch (Exception)
{
//出错后直接抛出
throw;
}
finally
{
if (webResponse != null)
{
//获得网络响应流
using (StreamReader responseReader = new StreamReader(webResponse.GetResponseStream(), encoding))
{
responseStr = responseReader.ReadToEnd();//获得返回流中的内容
}
webResponse.Close();//关闭web响应流
}
}
return responseStr;
}
encoding为服务器接收的编码,例如:Encoding.GetEncoding("GBK")等
param post请求的参数 param1=123¶m2=中国¶m3=abc 这样的格式,中文部分不用使用编码,方法内转成byte[]时
会进行编码。
