Sending a string to a PHP page and having the PHP Page Display The String

问题

What I'm trying to do is have my PHP page display a string that I've created through a function in my C# application, via System.Net.WebClient.

That's really it. In it' s simplest form, I have:

WebClient client = new WebClient();  
string URL = "http://wwww.blah.com/page.php";
string TestData = "wooooo! test!!";

byte[] SendData = client.UploadString(URL, "POST", TestData);

So, I'm not even sure if that's the right way to do it.. and I'm not sure how to actually OBTAIN that string and display it on the PHP page. something like print_r(SendData) ??

ANY help would be greatly appreciated!

回答1:

There are two halves to posting. 1) The code that posts to a page and 2) the page that receives it.

For 1) Your C# looks ok. I personally would use:

string url = "http://wwww.blah.com/page.php";
string data = "wooooo! test!!";

using(WebClient client = new WebClient()) {
    client.UploadString(url, data);  
}

For 2) In your PHP page:

if ( $_SERVER['REQUEST_METHOD'] === 'POST' )
{
    $postData = file_get_contents('php://input');
    print $postData;
}

Use This Codes To Send String From C# With Post Method

       try
       {
            string url = "";
            string str = "test";
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
            req.Method = "POST";
            string Data = "message="+str;
            byte[] postBytes = Encoding.ASCII.GetBytes(Data);
            req.ContentType = "application/x-www-form-urlencoded";
            req.ContentLength = postBytes.Length;
            Stream requestStream = req.GetRequestStream();
            requestStream.Write(postBytes, 0, postBytes.Length);
            requestStream.Close();

            HttpWebResponse response = (HttpWebResponse)req.GetResponse();
            Stream resStream = response.GetResponseStream();

            var sr = new StreamReader(response.GetResponseStream());
            string responseText = sr.ReadToEnd();


        }
        catch (WebException)
        {

            MessageBox.Show("Please Check Your Internet Connection");
        }

and php page

 <?php 
    if (isset($_POST['message']))
    {
        $msg = $_POST['message'];

        echo $msg;

    }

   ?>
