在javascript中执行curl请求？ [英] Perform curl request in javascript?

问题描述

是否可以在jQuery或javascript中发送curl请求？

Is it possible to send a curl request in jQuery or javascript?

这样的事情：

curl \
-H 'Authorization: Bearer 6Q************' \
'https://api.wit.ai/message?v=20140826&q='

因此，在提交表格的PHP中，像这样：

So, in PHP on submission of a form, like this:

$header = array('Authorization: Bearer 6Q************');
$ch = curl_init("https://api.wit.ai/message?q=".urlEncode($_GET['input']));
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
curl_close($ch);

我要做的是执行此卷曲请求，返回json然后我计划用jQuery的 $。get（）函数解析它。

What I'm trying to do is perform this curl request, which returns json and then I plan on parsing it with jQuery's $.get() function.

推荐答案

curl是一个命令（在Linux和PHP中）。 Curl通常会发出HTTP请求。

curl is a command (in linux and PHP). Curl typically makes an HTTP request.

您真正想做的是从javascript发出HTTP（或XHR）请求。

What you really want to do is make an HTTP (or XHR) request from javascript.

使用这个词汇，你会发现一堆例子，对于初学者来说：
使用jquery和ajax发送授权标头

Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax

基本上你要调用 $。ajax 有一些标题选项等。

Essentially you will want to call $.ajax with a few options for the header, etc.

$.ajax({
        url: 'https://api.wit.ai/message?v=20140826&q=',
        beforeSend: function(xhr) {
             xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
        }, success: function(data){
            alert(data);
            //process the JSON data etc
        }
})
