MooTools CORS请求与本机Javascript

问题描述

我有这个MooTools代码：

  new Request.JSON（{
 method：'POST'，
 url：URL，/ * URL到另一个域* / 
 onSuccess：function（r）{
 callback（r）; 
} 
}）post ）; 
  

此代码不发送POST请求（仅限OPTIONS）...
在下面的代码（它的工作原理）：

  var http = null，
 params = Object.toQueryString ）; 
 try {
 http = new XMLHttpRequest（）; 
} catch（e）{
 try {
 http = new ActiveXObject（Msxml2.XMLHTTP）; 
} catch（e）{
 try {
 http = new ActiveXObject（Microsoft.XMLHTTP）; 
} catch（e）{
 http = null; 
 alert（您的浏览器不支持AJAX！）; 
} 
} 
} 
 var url = URL; 
 http.onreadystatechange = function（）{
 if（http.readyState == 4&& http.status == 200）{
 var jsonData = JSON.parse（http.responseText ）; / * OR EVAL * / 
 callback（jsonData）; 
} 
}; 
 http.open（POST，url）; 
 http.setRequestHeader（Content-Type，application / x-www-form-urlencoded）; 
 http.send（params）; 
  

EDIT ：

尝试： .setHeader（'Content-Type'，'application / x-www-form-urlencoded'）;

..在哪里可以有问题？

谢谢！

解决方案

这是因为MooTools会将一些额外的东西包含在请求头中。

例如。如果您的htaccess说：

 标题集Access-Control-Allow-Origin：* 
  
 $> 
 c> var foo = new Request（{
 url：'http://fragged.org/Epitome/example/data/'，
 method：'get'，
 onComplete：function data）{
 //返回一个名字和姓氏的对象
 new Element（'div [html ={name} {surname}]'substitute（JSON.decode（data）））。 inject（document.body）; 
} 
}）; 
 
 //需要删除，否则CORS需要特别匹配
 delete foo.headers ['X-Requested-With']; 
 foo.send（）; 
  
这就是为什么你只能看到OPTIONS预飞。它不喜欢你：）
 
 
 
您可以将 .htaccess 更改为 X-Requested-With ，这可能是一些额外的安全性。
 
 
 
请参阅一个工作的例子 - 我刚才那时我想得到这个更改请求已修复。 
 
I have this MooTools code:
new Request.JSON({
  method: 'POST',
  url: URL, /*URL TO ANOTHER DOMAIN*/
  onSuccess: function(r){
    callback(r);
  }
}).post(data);
And this code doesn't send POST requests (OPTIONS only)...Look at the code below (it works great):
var http = null,
  params = Object.toQueryString(data);
try {
  http = new XMLHttpRequest();
} catch (e) {
  try {
    http = new ActiveXObject("Msxml2.XMLHTTP");
  } catch (e) {
    try {
      http = new ActiveXObject("Microsoft.XMLHTTP");
    } catch (e) {
      http = null;
      alert("Your browser does not support AJAX!");
    }
  }
}
var url = URL;
http.onreadystatechange = function () {
  if (http.readyState == 4 && http.status == 200) {
    var jsonData = JSON.parse(http.responseText); /*OR EVAL*/
    callback(jsonData);
  }
};
http.open("POST", url);
http.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
http.send(params);
EDIT:
Tried: .setHeader('Content-Type','application/x-www-form-urlencoded');
Still nothing... Where can there be a problem?
Thanks!
 解决方案 
This is because MooTools bundles some extra stuff with the request headers.
eg. if your htaccess says:
Header set Access-Control-Allow-Origin: *
you need to craft your request like that:
var foo = new Request({
    url: 'http://fragged.org/Epitome/example/data/',
    method: 'get',
    onComplete: function (data) {
        // returns an object with name and surname  
        new Element('div[html="{name} {surname}"]'.substitute(JSON.decode(data))).inject(document.body);
    }
});

// need to remove that or CORS will need to match it specifically
delete foo.headers['X-Requested-With'];
foo.send();    
This is why you are only seeing the OPTIONS pre-flight. It does not like you :)
You could change the .htaccess to also match X-Requested-With, which is probably some extra "security".
See http://jsfiddle.net/7zUSu/1/ for a working example - I did that a while ago when I wanted to get this change to Request https://github.com/mootools/mootools-core/issues/2381 fixed.
