我目前正在 windows phone 上开发一个移动应用程序，它要求我向位于服务器上的 PHP 文件发送请求。

我遇到了一个问题，即请求在服务器上引发错误，但当我更改代码以分页本地 PHP 文件时却没有。任何想法为什么？

这是我的请求代码：

     string sendString = "";
        sendString += "&lat=" + (App.Current as App).mapCenter.Latitude;
        sendString += "&lng=" + (App.Current as App).mapCenter.Longitude;
        sendString += "&address=" + (App.Current as App).locationAddress;
        if (checkNumber(CountryCode.Text, AreaCode.Text, Number.Text))
        {
            sendString += "&phone=" + CountryCode.Text + "" + AreaCode.Text + "" + Number.Text;
        }
        else
        {
            MessageBox.Show("Phone number invalid");
        }
        if (checkEmail(email.Text))
        {
            sendString += "&email=" + email.Text;
        }
        else
        {
            MessageBox.Show("Invalid Email");
        }
        sendString += "device=WindowsPhone";
        sendString += (bool)prefsms.IsChecked ? "&contactMethod=sms" : "&contactMethod=email";
        ListPickerItem selectedItem = (ListPickerItem)ServiceType.SelectedItem; //Cast listpickeritem into String
        string content = (string)selectedItem.Content;
        sendString += "&serviceType=" + content;
        sendString += "&version=2.0";
        sendString += "&language=" + CultureInfo.CurrentUICulture.TwoLetterISOLanguageName;
        (App.Current as App).watcher.Stop();
        sendData = sendString;


        if ((checkNumber(CountryCode.Text, AreaCode.Text, Number.Text)) && (checkEmail(email.Text)))
        {
            //Send data to server 
            HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost/test.php");
            myRequest.Method = "POST";
            myRequest.ContentType = "application/x-www-form-urlencoded";
            myRequest.BeginGetRequestStream(new AsyncCallback(RequestCallBack), myRequest);
        }
        else
        {
        }

private void RequestCallBack(IAsyncResult asyncresult)
{
        HttpWebRequest myRequest = asyncresult.AsyncState as HttpWebRequest;
        Stream dataStream = myRequest.EndGetRequestStream(asyncresult);
        //Avoid trashing procedure
        this.Dispatcher.BeginInvoke(delegate()
        {
            StreamWriter writer = new StreamWriter(dataStream);
            writer.Write(sendData);
            writer.Flush();
            writer.Close();
            //Expect a response
            myRequest.BeginGetResponse(new AsyncCallback(ResponseCallBack), myRequest);
        });

    }
  private void ResponseCallBack(IAsyncResult asyncresult)
    {
        HttpWebRequest myRequest = asyncresult.AsyncState as HttpWebRequest;
        HttpWebResponse myResponse = (HttpWebResponse)myRequest.EndGetResponse(asyncresult);
        // Avoid trashing the procedure
        this.Dispatcher.BeginInvoke(delegate()
        {
            // Retrieve response stream
            Stream responseStream = myResponse.GetResponseStream();
            StreamReader reader = new StreamReader(responseStream);
            // Show response
            responseTxt = reader.ReadToEnd();
            MessageBox.Show("" + responseTxt);
        });

    }

我正在向服务器发送一个字符串，服务器的PHP代码是这样的（测试的php完全一样）：

require_once("includes/globals.php");

$vars = ($PRODUCTION)?$_POST:$_REQUEST;

$MINIMUM_VERSION = 2.0;
function validServiceType($type)
{
return $type == "taxi" || $type == "ladies" || $type == "limo" || $type ==   "handicap";
}

if(!isset($vars['version']) || ((float)$vars['version']) < $MINIMUM_VERSION)
{
echo "oldVersion";
}
elseif(isset($vars['lat'], $vars['lng'], $vars['phone'], $vars['language']))
{
     /*do stuff */
if($data['contactMethod'] == "email" && $data['email'] == "")
{
    echo "invalid";
    die();
}
if(DB_AddHail($data))
    echo "processing";
else if (($company = DB_GetReferralTaxi($data['lat'], $data['lng'], $data['serviceType'])))
{
    /*do some more stuff*/
}
else
    echo "sorry";
}
else
{
echo "invalid";
}

?>

我不断收到 OldVersion 错误，但我已经将版本号设置为 2.0...关于发生了什么的任何想法？

更新：我现在已经能够找出问题的根源；HttpWebRequest 根本没有向服务器发送任何数据；我的 $_POST 只是一个空数组。关于为什么的任何想法？

更新 2：我得到的错误是错误 302（“我使用的 URI 只是 http:// 而不是 https://）。但是在将协议更改为 https:// 后，它仍然不起作用。我的代码对那部分不正确吗？

您可以尝试在以 if(!isset($vars['version'])) 开头的行之前添加：

echo "version: " . $vars['version']; 
exit;

查看它是否向浏览器输出任何内容。可能是您使用的 php 版本不喜欢 $vars = ($PRODUCTION)?$_POST:$_REQUEST; 语法，您可能必须手动通过，等等

$vars['version']=$_POST['version']; 
$vars['somethingElse']=$_POST['somethingElse']

ETC...

确保您在 5.4.3 上并使用 phpinfo(); 运行您的脚本；去检查。尝试更改您是 PHP/C# 来接收/发送 GET 请求而不是 POST 请求。

这样，您至少可以测试以查看何时从浏览器向 php 脚本发送请求，例如http://yourdomain.com/script.php?name=John+Smith&Age=23，如果您得到预期的结果。下载https://addons.mozilla.org/en-US/firefox/addon/live-http-headers/以在您检查结果时从浏览器的角度检查标头的工作方式。
