AJAX发布不适用于HTTPS [英] AJAX post not working with HTTPS

问题描述

我在使用jquery post函数时遇到了一个令人沮丧的问题，这可能是由于不了解其正确工作方式所致.

I am having a rather frustrating problem with the jquery post function that probably stems from not understanding how it works correctly.

我有一个函数，该函数应该将一些表单信息发布到我编写的php脚本中，然后该脚本针对API运行curl请求，以解决javascript的跨域策略.只要它提交到"http"，它似乎就可以正常工作，但是当我将其发送到"https"时，表单永远不会提交.

I have a function that should post some form information to a php script that I wrote and that script then runs curl requests against an API to get around the cross-domain policy of javascript. It seems to work fine as long as it submits to "http" but when I send it to "https" the form never gets submitted.

我在计算机上运行了Wireshark，直到我使URL使用http之前，它都未显示出指向目标ip的流量.我在服务器上具有基本的身份验证，因此我通过url传递了用户名和密码，但是在那里没有经过测试，得到了相同的结果.

I ran wireshark on my computer and it showed no traffic towards the destination ip until I made the url use http. I have basic auth on the server so I am passing the user and password through the url, but tested without that there and got the same results.

这是无效代码:

$j.post("https://<api user>:<password>@<ip>:444/ProxyScript.php", 
         $j("#spoke_ticket").serialize(),
         function(msg) { 
              log_status(msg);
              fade_status();
              $j(':input','#createtheticket')
                   .not(':button, :submit, :reset, :hidden')
                   .val('')
                   .removeAttr('checked')
                   .removeAttr('selected');
               });

这是工作功能:

$j.post("http://<other ip>/ProxyScript.php",  
        $j("#spoke_ticket").serialize(),
        function(msg) { 
              log_status(msg);
              fade_status();
              $j(':input','#createtheticket')
                   .not(':button, :submit, :reset, :hidden')
                   .val('')
                   .removeAttr('checked')
                   .removeAttr('selected');
               });

关于为什么不发送流量的任何想法?让我知道是否遗漏了一些关键信息或其他内容.

Any ideas as to why the traffic is not being sent? Let me know if I left out some key information or anything.

感谢您的帮助

推荐答案

为什么不使用代理来解决跨域问题?听起来更容易.一个简单的例子是，当我想获取有关县，道路名称等的丹麦政府国家地理数据时(对我来说幸运的是，它们的数据是json或XML可选)

Why not use a proxy to get over the cross-domain issue? It sounds more easy. An simple example is when i want to retrieve the danish administration national geo-data for counties,road names and so on (lucky for me, their data is in json or XML optional)

简化的proxy.php

simplified proxy.php

<?
header('Content-type: application/json');
$url=$_GET['url'];
$html=file_get_contents($url);
echo $html;
?>

在ajax中，获取县边界的纬度/经度

in ajax, get the lat/longs for a county borderline

var url= "proxy.php?url=https://geo.oiorest.dk/"+type+"/"+nr+"/graense.json";           
$.ajax({
  url: url,
  dataType: 'json',
  success:  function (data) {
   ...

}); 

请注意https-实际示例中的网址可能是 https://geo.oiorest.dk/kommuner/0810/graense.json

notice the https - the url could be, real example, https://geo.oiorest.dk/kommuner/0810/graense.json
