从C＃WinForm将数据发布到PHP页面

我有一个winForms NET3.5SP1应用程序，并希望将数据POST到PHP页面。

我也将把它作为JSON传递，但是想要先直接使用POST。

这是代码：

Person p = new Person(); p.firstName = "Bill"; p.lastName = "Gates"; p.email = "[e-mail]"; p.deviceUUID = "abcdefghijklmnopqrstuvwxyz"; JavaScriptSerializer serializer = new JavaScriptSerializer(); string s; s = serializer.Serialize(p); textBox3.Text = s; // s = "{\"firstName\":\"Bill\",\"lastName\":\"Gates\",\"email\":\"[e-mail]\",\"deviceUUID\":\"abcdefghijklmnopqrstuvwxyz\"}" HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.davemateer.com/ig/genius/newuser.php"); //WebRequest request = WebRequest.Create("http://www.davemateer.com/ig/genius/newuser.php"); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; //byte[] byteArray = Encoding.UTF8.GetBytes(s); byte[] byteArray = Encoding.ASCII.GetBytes(s); request.ContentLength = byteArray.Length; Stream dataStream = request.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close (); WebResponse response = request.GetResponse(); textBox4.Text = (((HttpWebResponse)response).StatusDescription); dataStream = response.GetResponseStream (); StreamReader reader = new StreamReader(dataStream); string responseFromServer = reader.ReadToEnd (); textBox4.Text += responseFromServer; reader.Close (); dataStream.Close (); response.Close (); 

PHP5.2代码是：

这回来了：

 array(0) {} 

有任何想法吗？ 我希望它返回我刚刚传递给它的值，以certificate我可以从服务器端访问数据。

我相信你需要正确编码并发送实际的post内容。 看起来你只是序列化为JSON，PHP不知道该怎么做（即，它不会将其设置为$_POST值）

 string postData = "firstName=" + HttpUtility.UrlEncode(p.firstName) + "&lastName=" + HttpUtility.UrlEncode(p.lastName) + "&email=" + HttpUtility.UrlEncode(p.email) + "&deviceUUID=" + HttpUtility.UrlEncode(p.deviceUUID); byte[] byteArray = Encoding.ASCII.GetBytes(postData); // etc... 

这应该在PHP集中得到你的$_POST变量。 稍后，当您切换到JSON时，您可以执行以下操作：

 string postData = "json=" + HttpUtility.UrlEncode(serializer.Serialize(p) ); 

并从PHP抓取：

 $json_array = json_decode($_POST['json']);
