I recognize I am a little late to the party here, and this question, however, I was having the exact same problem. @FK82 indicated the right solution and I wanted to document it, as I've tried it and it works.
我知道我参加聚会有点晚了，但是这个问题，我遇到了完全相同的问题。@FK82 指出了正确的解决方案，我想记录它，因为我已经尝试过并且它有效。
$.ajax({
url: "http://somefancyurl.com/api/do_it",
data: { id:"user" },
dataType: "jsonp",
success: function(data) {
console.log(data);
}
});
If I do not specify jsonpI get the 407 Proxy Authentication Requirederror.
如果我不指定 jsonp，我会收到407 Proxy Authentication Required错误。
- Although the original question didn't specify JQuery, I was able to test successfully with FireFox 3.6.x, and IE7 using this approach & JSONP.
- 虽然最初的问题没有指定 JQuery，但我能够使用这种方法和 JSONP 在 FireFox 3.6.x 和 IE7 上成功测试。

Proxy Authentication is simply an existence of a http header field called "Proxy-Authorization"
代理身份验证只是存在一个名为的 http 标头字段 "Proxy-Authorization"
Browsers are supposed to send those stuff automatically.
浏览器应该自动发送这些东西。
But since you could add some custom header to ajax requests, you could try setting it manually.
但是由于您可以向 ajax 请求添加一些自定义标头，您可以尝试手动设置它。
request.setRequestHeader("Proxy-Authorization", value);
- requestis the XMLHttp object
- valueis the base64 encoded version of
username:password
- request是 XMLHttp 对象
- 值是 base64 编码的版本
username:password
Note that I am not sure thats the case or not, correct me if I am wrong.
请注意，我不确定是不是这样，如果我错了，请纠正我。
Or some page I found on google says to add X-Requested-With, may be worth to try that too.
或者我在谷歌上找到的某个页面说要添加X-Requested-With，也可能值得一试。
request.setRequestHeader("X-Requested-With", "XMLHttpRequest");
