如何使用基本身份验证发出dojo.request.xhr GET请求 [英] How to make dojo.request.xhr GET request with basic authentication

问题描述

我查看了 Dojo v的文档.1.9 request / xhr
，我找不到包含基本身份验证的示例。

I look at the documentation for Dojo v.1.9 request/xhr and I cannot find example that includes basic authentication.

我如何以及在何处将用户名和密码包括在其中Dojo XHR选项？

How and where do I include the User name and Password in the Dojo XHR options?

require(["dojo/request/xhr"], function(xhr){
  xhr("example.json", {
    // Include User and Password options here ?
    user: "userLogin"
    password: "userPassword"
    handleAs: "json"
  }).then(function(data){
    // Do something with the handled data
  }, function(err){
    // Handle the error condition
  }, function(evt){
    // Handle a progress event from the request if the
    // browser supports XHR2
  });
});

谢谢。

推荐答案

确实，您应该能够使用 user 和 password 属性传递用户名和密码在 options 对象中。

Indeed, you should be able to pass the user and password with the user and password property in the options object.

在Dojo的早期版本中已对此进行了记录，但现在看来它们不是 t。但是，我刚刚对其进行了测试，它似乎在URL中添加了用户名和密码，例如：

In previous versions of Dojo this was documented, but it seems that now they aren't. However, I just tested it and it seems to add the username and password to the URL, like:

http://user:password@myUrl/example.json

通常，浏览器应该能够翻译此URL，因此请求

Normally the browser should be capable of translating this URL so the request headers are set.

您也可以手动设置这些标题，例如使用：

You could also set these headers manually, for example by using:

xhr("example.json", {
    headers: {
        "Authorization": "Basic " + base64.encode(toByteArray(user + ":" + pass))
    }
}).then(function(data) {
    // Do something 
});

但是，这需要 dojox / encoding / base64 模块和以下函数：

However, this requires the dojox/encoding/base64 module and the following function:

var toByteArray = function(str) {
    var bytes = [];
    for (var i = 0; i < str.length; ++i) {
        bytes.push(str.charCodeAt(i));
    }
    return bytes;
};
