响应示例

响应结构与发送文本消息相同

成功时 data 就是刚发出的完整消息,字段见发送文本消息的响应示例data.content 回显你发送的内容或上传字段,形状随消息类型不同,见消息模块总览的码表

响应字段

字段类型说明
codeint64统一封套状态码:0=成功,负数=失败
detailstring附加明细,通常为空
messagestring文案:成功为 ok;失败形如 -码|描述
timestring服务端处理时间 YYYY-MM-DD HH:MM:SS

常见错误

下表为企微错误码。业务失败时顶层 code=-1,具体错误码在 message| 前,例如 -3004|参数错误;鉴权与网关错误见错误码

错误码含义怎么办
-4014过期或错误的 uinconversationIdpersonal/getInfo 取当前 uin
-3020用自聊伪房间 roomId 作发送目标给自己发用当前账号 uin
-3004参数错误检查字段名与类型,数字 id 不能传字符串
