推荐答案

如果服务器不支持CORS，或不使用JSONP响应，你需要使用一个中间人脚本来获取数据。

If the server does not support cors, or does not employ JSONP responses you will need to use a middleman script to get the data.

JS

$.ajax({
    type: "POST",
    url: 'https://YourOwnDomain.com/myPhpScript.php',
    success: success,
    dataType: "json"
});

PHP

...
$outputjson = curl_exec($ch);
echo $outputjson;
die;

如果他们使用JSONP响应，你可以使用jQuery的JSONP的能力来获取数据，只看如何调用自己的休息服务，他们应该这样做一个JSONP调用如果他们这样做允许它的细节其他域的文档。一般的code会是这样的：

If they employ jsonp responses you can use jQuery's jsonp abilities to get the data, look at the other domain's documentation on how to call their rest service they should have details about doing a jsonp call if they do allow it. The general code would be something like:

$data = {
        'TokenID':$tokenid,
        'APIKey':$api_key,
        'EcryptedData':$encrypted_data,
        'TokenScheme':4};

$.ajax({
    type: "POST",
    url: 'https://testingonetwo.com/rest/?callback=?',
    data: {data:$data},
    success: success,
    dataType: "jsonp"
});

不过，你有什么看起来像一个API密钥和TokenID，如果这些都应该是保密的（即最终用户不应该能够看到他们），那么你不应该使用，显示这些细节的JavaScript，即使用中间人脚本。

But as you have what looks like a API key and a TokenID if these are supposed to be secret (ie the end users should not be able to see them) then you shouldnt use the javascript that shows those details, ie use the middleman script.
