java微信上传永久图文消息返回40007

String peram = "{\"articles\": [{\"thumb_media_id\":\"qI6_Ze_6PtV7svjolgs-rN6stStuHIjs9_DidOHaj0Q-mwvBelOXCFZiq2OsIU-p\",\"author\":\"xxx\",\"title\":\"Happy Day\",\"content_source_url\":\"www.qq.com\",\"content\":\"content\",\"digest\":\"digest\",\"show_cover_pic\":1},{\"thumb_media_id\":\"qI6_Ze_6PtV7svjolgs-rN6stStuHIjs9_DidOHaj0Q-mwvBelOXCFZiq2OsIU-p\",\"author\":\"xxx\",\"title\":\"Happy Day\",\"content_source_url\":\"www.qq.com\",\"content\":\"content\",\"digest\":\"digest\",\"show_cover_pic\":0}]}";

WebClient webclient = new WebClient();
String data = webclient.getWebContentByPost(url,peram);

数据是微信的事例数据，同样显示40007
自己上传的永久图片的thumb_media_id同样也报40007

微信上传图文出现40007，invalid media_id hint解决方案：
