XMLHttpRequest无法通过基本身份验证 [英] XMLHttpRequest fails basic authentication

问题描述

任何想法，为什么XMLHttpRequest在 Pebble JS Framework 无法在Android上进行基本身份验证，但可以在iOS上运行?

Any idea why XMLHttpRequest with correct credentials in Pebble JS Framework fails basic authentication on Android but works in iOS?

完全相同的代码，大致如下:

Exactly the same code, along the lines of:

var req = new XMLHttpRequest();
req.open(method, url, true, user, pass);
req.send(data);
req.onreadystatechange = function() { ... }

从Android Pebble应用返回401，但在iOS中正确进行身份验证.

Returns 401 in from Android Pebble app, but authenticates correctly in iOS.

推荐答案

我找到了一种适用于Android的变通方法.

I found a workaround that worked for me on Android.

不知道为什么，但是直接通过身份验证的请求:

Don’t know why but direct authenticated request:

    req.open(method, fullurl, true, user, pass);
    req.send(data);

对我不起作用–它总是返回401.因此，我改为尝试通过标头设置基本身份验证:

didn’t work for me – it always returned 401. So Instead I tried to set basic authentication via header:

    req.open(method, fullurl, true);
    req.setRequestHeader("Authorization", "Basic " + Base64.encode(user + ":" + pass)); 
    req.send(data);

(从此处获取Base64: https://stackoverflow.com/a/246813/961695 )–它奏效了！也许在Android上的XmlHttpRequest实现中存在错误.

(where Base64 is taken from here: https://stackoverflow.com/a/246813/961695) – and it worked! Perhaps there’s a bug in XmlHttpRequest implementation on android.
