decodeURIComponent(uri)不工作？

Question

我使用Ajax发布内容，并使用http.send(encodeURIComponent(params));进行编码...但我无法在PHP中解码它们。我正在使用POST，所以我不认为它需要编码？我对如何解码PHP中的值感到困惑……

params = "guid="+szguid+"&username="+szusername+"&password="+szpassword+"&ip="+ip+"&name="+name+"&os="+os;
        //alert(params);
        document.body.style.cursor = 'wait';//change cursor to wait

        if(!http)
            http = CreateObject();  

        nocache = Math.random();

        http.open('post', 'addvm.php');
        http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        http.setRequestHeader("Content-length", params.length);
        http.setRequestHeader("Connection", "close");
        http.onreadystatechange = SaveReply;
       http.send(encodeURIComponent(params));

encodeURIComponent将对分隔键/值对的所有&s和=s进行编码。您需要在每个部件上单独使用它。如下所示：

 params = 
 "guid="      + encodeURIComponent(szguid)     + 
 "&username=" + encodeURIComponent(szusername) +
 "&password=" + encodeURIComponent(szpassword) +
 "&ip="       + encodeURIComponent(ip)         +
 "&name="     + encodeURIComponent(name)       +
 "&os="       + encodeURIComponent(os);
    //alert(params);
    document.body.style.cursor = 'wait';//change cursor to wait

    if(!http)
        http = CreateObject();  

    nocache = Math.random();

    http.open('post', 'addvm.php');
    http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    http.setRequestHeader("Content-length", params.length);
    http.setRequestHeader("Connection", "close");
    http.onreadystatechange = SaveReply;
    http.send(params);

如果您正在提交来自JS的编码值，并且想要在PHP中decode它们，您可以这样做：

// decode POST values so you don't have to decode each pieces one by one
$_POST = array_map(function($param) {
            return urldecode($param);
        }, $_POST);

// assign post values after every value is decoded
