我尝试使用带有 POST 的 WebRequest 发送数据,但我的问题是没有数据流式传输到服务器。
string user = textBox1.Text;
string password = textBox2.Text;
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "username" + user + "&password" + password;
byte[] data = encoding.GetBytes(postData);
WebRequest request = WebRequest.Create("http://localhost/s/test3.php");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
Stream stream = request.GetRequestStream();
stream.Write(data, 0, data.Length);
stream.Close();
WebResponse response = request.GetResponse();
stream = response.GetResponseStream();
StreamReader sr99 = new StreamReader(stream);
MessageBox.Show(sr99.ReadToEnd());
sr99.Close();
stream.Close();
最佳答案
这是因为您需要使用 =
等号来分配您发布的参数:
byte[] data = Encoding.ASCII.GetBytes(
$"username={user}&password={password}");
WebRequest request = WebRequest.Create("http://localhost/s/test3.php");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
string responseContent = null;
using (WebResponse response = request.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
using (StreamReader sr99 = new StreamReader(stream))
{
responseContent = sr99.ReadToEnd();
}
}
}
MessageBox.Show(responseContent);
请参阅发布数据格式中的username=
和&password=
。
你可以在这个 fiddle 上测试它.

您的 PHP 脚本中的参数名称似乎与您问题中使用的参数名称不同。
