使用postman测试正常，使用代码测试的时候报获取不到openid，或openid为空，使用自己的client获取传过来的参数是正常的，

errcode:40003 errmsg:invalid openid rid: 60754300-6c199ef6-616a2735

client发起请求

thing31.Value = "力顶天地"
thing3.Value = "回复消息"
time4.Value = "2020-01-01 12:20"
data1.Thing2 = thing31
data1.Time4 = time4
data1.Thing3 = thing3
message.Data = data1
message.Template_id = "QMd_2_UXn0mYnB5hHWTGVXgqE1BMeXPv08FO3YFHiOo"
message.ToUser = "ocI0k0UScnY4vqLnLTwUwzOWejzY"
message.Page = "/pages/product_info/product_info?id=027820373b8f88b9ffd31517ed65d1a8"
message.Miniprogram_state = "developer"
wxMessage, err = json.Marshal(message)
if err != nil {
   e.Error(http.StatusServiceUnavailable, "json转化错误", *c)
   return
}
str, err = WxToken()
client := http.Client{}
resp, err = client.Post(fmt.Sprintf("https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token=%s", str), "application/json", bytes.NewBuffer(wxMessage))

上面的请求地址已更换成自己的

server端接收参数

router := gin.Default()
router.POST("/test", func(c *gin.Context) {
   var message Message
   err := c.Bind(&message)
   if err != nil {
      fmt.Println(err)
   }
   me,_ := json.Marshal(message)
   fmt.Println(string(me))
   c.JSON(http.StatusOK,me)
})
router.Run(":8888")

获取的参数
