/**
 * 群发接口
 * PS:群发之前调用“预览接口”进行测试
 * PS:通过第三方后台调用微信上传图片素材接口，获取图片url,如:{"url":"http:\/\/mmbiz.qpic.cn\/mmbiz_jpg\/BdxWN2kspVgJOFpRHJojlWmbl0pMxUaJibxrb33qm8Hkukvr6WTIxFibiccRhf5kibfpnEYMEOqKYSwuIe82w2O2Xg\/0"}
 *
 * 图文消息群发步骤:
 * 1.调用“新增临时素材”接口,获取到media_id:https://api.weixin.qq.com/cgi-bin/media/upload?access_token=ACCESS_TOKEN&type=TYPE(调用"新增永久素材"接口，获取media_id测试可以)
 * 2.调用"上传图文消息素材"接口，传入参数thumb_media_id即为上面接口返回的media_id,调用成功后会返回一个media_idhttps://api.weixin.qq.com/cgi-bin/media/uploadnews?access_token=ACCESS_TOKEN
 * 3.调用"预览接口"传入参数media_id即为上面返回的media_id，https://api.weixin.qq.com/cgi-bin/message/mass/preview?access_token=ACCESS_TOKEN
 * 4.预览成功后，调用"根据标签进行群发"或者"根据OpenID列表群发"进行群发
 *
 *
 * 调用"新增永久素材"接口中的参数"thumb_media_id"是由调用"新增其他类型永久素材"接口返回的media_id，https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1444738729
