问题描述
我做一个POST请求的页面getremote.php用POST数据,但在$ _POST数组似乎是空的。将不胜感激,如果有人能告诉我,我做错了。
I make a post request to the the page getremote.php with post data but the $_POST array seems to be empty. Would be grateful if anyone can tell me what I've done wrong.
JavaScript的code,使请求
The javascript code to make the request is
var postdata = "Content-Type: application/x-www-form-urlencoded\n\nedits=" + this.createEditXMLtext(this.editXMLstruct);
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
dispmes("processing edits");
xmlhttp.open("POST",userProfile.homeurl + "?remoteurl=" + userProfile.homeurl + "&cmdeditprofile&password=password",false);
xmlhttp.send(postdata);
var response = xmlhttp.responseXML;
在这里this.createEditXMLtext(this.editXMLstruct)只是简单地创建一个字符串
where this.createEditXMLtext(this.editXMLstruct) simply creates a string
我还没有收到这个问题,似乎并不具有相同的解决方案,因为谁也发布类似问题的其他人。PHP的code在userProfile.homeurl +是
I haven't had this problem before and don't seem to have the same solution as other people who have posted similar problems.The php code at userProfile.homeurl + " is
header("Content-type: text/xml");
$query = '';
foreach( $_POST as $key => $value ){
$query .= "$key=$value&";
}
echo do_post_request($_GET['remoteurl'] . $qstring,$query);
但字符串$查询总是空的 - 我通过添加回声$查询到文件底部
but the string $query is always empty - I checked it by adding echo $query to the bottom of the file
推荐答案
您传递给的应该是整个身体后,你已经包含在它的头。当该机构达到PHP,它将无法解析为EN codeD格式的数据。
The value you pass to send() should be the entire post body, and you've included a header in it. When that body reaches PHP, it will fail to parse it as encoded form data.
相反,通过调用 setRequestHeader设置的数据类型()
//create the postdata, taking care over the encoding
var postdata = "edits=" + encodeURI(this.createEditXMLtext(this.editXMLstruct));
//let server know the encoding we used for the request body
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
//and here we go
xmlhttp.send(postdata);
