如何等待下一个POST请求

所以我想做的是当机器人收到/ uploadPhoto消息时,它等待下一条消息并检查是否包含照片。我尝试了许多不同的循环,包括do..while,if,while和其他解决方案。现在我想的是,我需要从doPost函数中调用doPost函数。有什么办法吗?

尝试做..while,if,while和其他循环。

function doPost(e){          

var contents = JSON.parse(e.postData.contents);
var id = contents.message.id;
var text = contents.message.text;

case "uploadPhoto":
sendText(id, "Upload a photo...");

        //endText(id, "Upload a photo to be displayed as your product%0AUsage: upload a photo with a caption /uploadPhoto");

        /**const zinutes_id = contents.message.message_id; 
        const zinutes_id_opa = zinutes_id + 1;
        while (true) {
          if (zinutes_id == zinutes_id_opa){
            if ("photo" in contents.message) {
              var photo = contents.message.photo[3].file_id;
              sendText(id, "okay " + photo);
              sendPhoto(id, photo);
              break;
            }
          }
        } */


       /**  if ("photo" in contents.message){
          var photo = contents.message.photo[3].file_id;
          sendText(id, "okay " + photo);
          sendPhoto(id, photo);
        } else {
          sendText(id, "Upload a photo!");
        }*/
        break;

}

  1. 将/ uploadPhoto文本发送到bot
  2. Bot短信返回“正在上传照片...”
  3. Bot等待下一条消息并解析其内容

编辑:

这是我设法做到的:

doPost(e){
  if(contents.message.includes("photo")){
    var fotke = contents.message.photo[3].file_id;
  }


  if (checkLastCommand(id) == "uploadPhoto") {
    if (fotke !== "undefined") {
     // @ts-ignore
     sheet.getRange(searchUser(id),6).setValue(fotke);
     sendText(id, fotke);
     // @ts-ignore
     sheet.getRange(searchUser(id),7).clear();
    } else {
     sendText(id, "this is not a photo");
     // @ts-ignore
     sheet.getRange(searchUser(id),7).clear();
  } else if (firstChar === '/') {
     case "uploadPhoto":
         sendText(id, "Upload a photo...");
         sheet.getRange(searchUser(id), 7).setValue("uploadPhoto");
         break;
  }


}
function checkLastCommand(x) {
  // @ts-ignore
  var z = sheet.getRange(searchUser(x), 7).getValue(); 
  return z;
} 

现在,它等待照片,但是由于某种原因,它在POST请求中找不到照片。我在单元格中得到“未定义”,并且机器人不响应照片,而是使用未定义来响应/(command)

显然,我想出了一个解决方案。

if ("photo" in contents.message) {
   var fotke = contents.message.photo[3].file_id;
} else {
   var text = contents.message.text;
   var firstChar = text.substr(0,1);
}

程序不希望读取已发送照片的file_id,因为它一直在等待文本消息。
