使用XMLHttpRequest从Javascript到PHP POST大数组

Question

I am trying to send a large array from Javascript to mySQL through PHP. 我正在尝试通过PHP将大型数组从Javascript发送到mySQL。 I am experimenting with POST but the following doesn't work. 我正在尝试POST，但以下操作无效。 The 'alert' in http.onreadystatechange pops open and appears to contain just the code below. http.onreadystatechange中的“警报”会弹出并显示仅包含以下代码。 Code seems pretty straightforward. 代码看起来很简单。 Any help is appreciated. 任何帮助表示赞赏。

<?php 

if (isset($_POST['params'])) {
echo 'YES isset';
$phpobj = ($_POST['params']);
echo $phpobj;

}else{
echo 'No isset';
}

?>


<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">

if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
http=new XMLHttpRequest();
}else{// code for IE6, IE5
http=new ActiveXObject("Microsoft.XMLHTTP");
}

var url = "PostArray.php";
var params = "lorem=ipsum&name=binny";
http.open("POST", url, true);

//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");

http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
    alert(http.responseText);
}
}
http.send(params);

</script>

Answer 1

there's no variable called params in the data you'd like to pass, only lorem and name 您要传递的数据中没有变量称为params，只有lorem和name
you don't even post that, because you haven't passed the variable params (in javascript) to http object 您甚至都不会发布它，因为您尚未将变量params（在javascript中）传递给http对象
