如果您的服务器需要HTTP基本身份验证，我可以想到两个选项：

If your server requires HTTP Basic Authentication, there are two options I can think of:

1. 将凭证放在网址 ftp：// username：password @ url


2. 直接设置自定义标题 options.headers = {'Authorization'：base64（'username'+'：'+'password'）}; li>
   

1. Put the credentials in the url ftp://username:password@url
2. directly set a custom header options.headers = {'Authorization': base64('username' + ':' + 'password') };

请注意，base64必须是一个编码如下所示凭证的函数：

Note that base64 must be a function that encodes the credentials like this:

base64= function(credentials) {
    var hash = btoa(credentials);
    return "Basic " + hash;
};
