微信公众号开发之新增永久其他（图片、声音、视频）素材（九）

对于常用的素材，开发者可通过本接口上传到微信服务器，永久使用。新增的永久素材也可以在公众平台官网素材管理模块中查询管理。
请注意：
1、最近更新：永久图片素材新增后，将带有URL返回给开发者，开发者可以在腾讯系域名内使用（腾讯系域名外使用，图片将被屏蔽）。
2、公众号的素材库保存总数量有上限：图文消息素材、图片素材上限为100000，其他类型为1000。
3、素材的格式大小等要求与公众平台官网一致：
图片（image）: 2M，支持bmp/png/jpeg/jpg/gif格式
语音（voice）：2M，播放长度不超过60s，mp3/wma/wav/amr格式
视频（video）：10MB，支持MP4格式
缩略图（thumb）：64KB，支持JPG格式
4、图文消息的具体内容中，微信后台将过滤外部的图片链接，图片url需通过"上传图文消息内的图片获取URL"接口上传图片获取。
5、"上传图文消息内的图片获取URL"接口所上传的图片，不占用公众号的素材库中图片数量的100000个的限制，图片仅支持jpg/png格式，大小必须在1MB以下。
6、图文消息支持正文中插入自己帐号和其他公众号已群发文章链接的能力。
<h3>一、新增其他类型永久素材</h3>
接口调用请求说明
通过POST表单来调用接口，表单id为media，包含需要上传的素材内容，有filename、filelength、content-type等信息。请注意：图片素材将进入公众平台官网素材管理模块中的默认分组。
http请求方式: POST，需使用https https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=ACCESS_TOKEN&type=TYPE 调用示例（使用curl命令，用FORM表单方式新增一个其他类型的永久素材，curl命令的使用请自行查阅资料）
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>

</tbody>
</table>
新增永久视频素材需特别注意
在上传视频素材时需要POST另一个表单，id为description，包含素材的描述信息，内容格式为JSON，格式如下： 
<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="18">

}</code></pre>
