POST data部分：
public string PostUrl(string url,string postData) //url:请求地址；postData:post data数据
{
string result = ""; //定义返回数据,为json数据
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Method = "POST";
req.Timeout = 800;
req.ContentType = ''application/json";
byte[] data = Encoding.UTF8.GetBytes(postData);
req.ContentLength = data.Length;
using (Stream reqStream = req.GetRequestStream()){
reqStream.Write(data,0,data.Length);
reqStream.Close();
}
try
{
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
Stream stream = resp.GetResponseStream();
using (StreamReader reader = new StreamReader(stream,Encoding.UTF8))
{
result = reader.ReadToEnd();
}
resp.Close()
stream.Close();
}
catch
{
}
return result;
}
关于POST DATA的构造
string jsonpost = "{\"keyword\":\"value\"}" //实际上就是把\"作为双引号使用
如果仅仅是request地址：
public string justRequest(string url){
string result = "";
try
{
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
Stream receiveStream = res.GetResponseStream();
StreamReader reader = new StreamReader(receiveStream,Encoding.UTF8)
returnstr = reader.ReadToEnd();
}
catch
{
}
return returnstr;
}
