有的企业微信往群聊发图片能成功，有的不行。调用光年发送图片的接口返回成功，实际上群里没有收到图片。
比如 下面 调用/msg/image接口的入参和出参：
发送消息：{"wxId":"1688854828454277","conversationId":"R:10947501519880675","content":null,"fileUrl":"https://wechat-luobo.oss-cn-shanghai.aliyuncs.com/284ba9a68e3f739cedfdb7e4fd469836.jpeg","atList":["1688854313522173"],"msgType":null,"title":null,"desc":null,"imageUrl":null,"url":null,"serverId":null,"quote":null}
发送结果：{"msg":"","code":0,"data":{"msgId":"6303156f-dccb-4c23-88cb-af4b0fa51fa2"}}
