通过ajax（铁ajax，聚合物）检索mailchimp列表详细信息

Question

我想调用mailchimp API来显示列表的详细信息，但我无法弄清楚如何发送auth凭据来显示列表。我尝试了一些东西，我不确定我是否在正确的轨道上。这是我已经试过：

<iron-ajax 
    auto 
    url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}' 
    handle-as='json' 
    method='get' 
    headers='{"Authorization": "Basic base64credentials"}' 
    debounce-duration='300' 
    last-response='{{json}}'></iron-ajax> 


<iron-ajax 
    auto 
    url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}' 
    handle-as='json' 
    method='get' 
    headers='{"user": "username:apikey"}' 
    debounce-duration='300' 
    last-response='{{json}}'></iron-ajax> 


<iron-ajax 
    auto 
    url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}' 
    handle-as='json' 
    method='get' 
    headers='{"Authorization": "Basic username:apikey"}' 
    debounce-duration='300' 
    last-response='{{json}}'></iron-ajax> 

Answer 1

使用btoa功能：

<iron-ajax 
auto 
url='https://us3.api.mailchimp.com/3.0/lists/{{listid}}' 
handle-as='json' 
method='get' 
headers='{"Authorization": "Basic [[basicAuth(username, apiKey)]]"}' 
debounce-duration='300' 
last-response='{{json}}'></iron-ajax> 
<script> 
    Polymer({ 
     ... 
     basicAuth(username, password) { 
      return window.btoa(username + ':' + password) 
     }, 
     ... 
    }); 
</script>
