微信公众号开发之获取用户列表和用户基本信息（五）

<h3>一、获取用户列表</h3>
公众号可通过本接口来获取帐号的关注者列表，关注者列表由一串OpenID（加密后的微信号，每个用户对每个公众号的OpenID是唯一的）组成。一次拉取调用最多拉取10000个关注者的OpenID，可以通过多次拉取的方式来满足需求。
接口调用请求说明

<h3>二、获取用户详情</h3>
在微信开发过程中，我们有时候需要获取用户的一些基础信息，尤其比如微信公众号和头像地址。获取用户信息主要是通过以下接口：
<div class="cke_widget_wrapper cke_widget_block cke_widget_codeSnippet cke_widget_wrapper_has cke_widget_selected" data-cke-widget-wrapper="1" data-cke-filter="off" data-cke-display-name="代码段" data-cke-widget-id="14">
<pre class="has cke_widget_element" data-cke-widget-data="{&quot;code&quot;:&quot;接口调用请求说明\nhttp请求方式: GET\nhttps://api.weixin.qq.com/cgi-bin/user/info?access_token=ACCESS_TOKEN&amp;openid=OPENID&amp;lang=zh_CN&quot;,&quot;classes&quot;:{&quot;has&quot;:1}}" data-cke-widget-upcasted="1" data-cke-widget-keep-attr="0" data-widget="codeSnippet"><code class="hljs">接口调用请求说明
http请求方式: GET
https://api.weixin.qq.com/cgi-bin/user/info?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN</code></pre>
<img class="cke_reset cke_widget_drag_handler lazyload" title="点击并拖拽以移动" alt="" width="15" height="15" data-cke-widget-drag-handler="1" data-src="data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw=="></div>
通过这个接口里的参数可以看到我们需要先获得access_token、openid这两个参数，access_token之前的文章已经说过了，openid是用户的微信公众号唯一标识
参数说明
<table class=" cke_show_border">
<thead>
<tr><th>参数</th><th>是否必须</th><th>说明</th></tr>
</thead>
<tbody>
<tr>
<td>access_token</td>
<td>是</td>
<td>调用接口凭证</td>
</tr>
<tr>
<td>openid</td>
<td>是</td>
<td>普通用户的标识，对当前公众号唯一</td>
</tr>
<tr>
<td>lang</td>
<td>否</td>
<td>返回国家地区语言版本，zh_CN 简体，zh_TW 繁体，en 英语</td>
</tr>
</tbody>
</table>
 
openid在用户关注我们的公众号时候就可以获取到，不过在那里openid叫FromUserName
<span class="cke_widget_wrapper cke_widget_inline cke_widget_image cke_image_nocaption cke_widget_selected" data-cke-widget-wrapper="1" data-cke-filter="off" data-cke-display-name="图像" data-cke-widget-id="13"><img class="has cke_widget_element lazyload" alt="" width="1200" height="863" src="https://img-blog.csdnimg.cn/2019122905013848.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTM1MjEyMjA=,size_16,color_FFFFFF,t_70" data-cke-widget-data="{&quot;hasCaption&quot;:false,&quot;src&quot;:&quot;https://img-blog.csdnimg.cn/2019122905013848.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTM1MjEyMjA=,size_16,color_FFFFFF,t_70&quot;,&quot;alt&quot;:&quot;&quot;,&quot;width&quot;:&quot;1200&quot;,&quot;height&quot;:&quot;863&quot;,&quot;lock&quot;:true,&quot;align&quot;:&quot;none&quot;,&quot;classes&quot;:{&quot;has&quot;:1}}" data-cke-widget-upcasted="1" data-cke-widget-keep-attr="0" data-widget="image" data-src="https://img-blog.csdnimg.cn/2019122905013848.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTM1MjEyMjA=,size_16,color_FFFFFF,t_70"><img class="cke_reset cke_widget_drag_handler lazyload" title="点击并拖拽以移动" alt="" width="15" height="15" data-cke-widget-drag-handler="1" data-src="data:image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==">
如果接口响应成功，则返回如下：
返回说明
正常情况下，微信会返回下述JSON数据包给公众号：
<div class="cke_widget_wrapper cke_widget_block cke_widget_codeSnippet cke_widget_wrapper_has cke_widget_selected" data-cke-widget-wrapper="1" data-cke-filter="off" data-cke-display-name="代码段" data-cke-widget-id="12">
