通过ajax (iron-ajax，聚合物)检索mailchimp列表详细信息

Question

我试图调用mailchimp API来显示列表的详细信息，但我不知道如何发送身份验证凭据来显示列表。我尝试了一些方法，但我不确定我是否走对了路。这是我尝试过的：

<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函数：

<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>
