我的nodejs代码和到官方whatsapp business API的连接有问题。
机器人正确连接了webhook,消息正确到达服务器,但我实现的使其响应的代码无效,我从上到下检查了代码,但我找不到故障。
我把代码留给你们,让你们有更多的背景:
whatsappController.js:

const fs = require("fs");
const myConsole = new console.Console(fs.createWriteStream("./logs.txt"));
const whatsappService = require("../services/whatsappService")

const VerifyToken = (req, res) => {

    try {
        var accessToken = "456E7GR****************************";
        var token = req.query["hub.verify_token"];
        var challenge = req.query["hub.challenge"];

        if(challenge != null && token != null && token == accessToken){
            res.send(challenge);
        }
        else{
            res.status(400).send();
        }
    } catch(e) {
        res.status(400).send();
    }
}

const ReceivedMessage = (req, res) => {
    try {
        var entry = (req.body["entry"])[0];
        var changes = (entry["changes"])[0];
        var value = changes["value"];
        var messageObject = value["messages"];

        if(typeof messageObject != "undefined"){
            var messages = messageObject[0];
            var text = GetTextUser(messages);
            var number = messages["from"];

            myConsole.log("Message: " + text + " from: " + number);
            whatsappService.SendMessageWhatsApp("The user say: " + text, number);
            
            myConsole.log(messages);
            myConsole.log(messageObject);
        }

        res.send("EVENT_RECEIVED");
    }catch(e) {
        myConsole.log(e);
        res.send("EVENT_RECEIVED");
    }
}

function GetTextUser(messages){
    var text = "";
    var typeMessage = messages["type"];
    if(typeMessage == "text"){
        text = (messages["text"])["body"];
    }
    else if(typeMessage == "interactive"){
        var interactiveObject = messages["interactive"];
        var typeInteractive = interactiveObject["type"];

        if(typeInteractive == "button_reply"){
            text = (interactiveObject["button_reply"])["title"];
        }
        else if(typeInteractive == "list_reply"){
            text = (interactiveObject["list_reply"])["title"];
        }else{
            myConsole.log("sin mensaje");
        }
    }else{
        myConsole.log("sin mensaje");
    }
    return text;
}

module.exports = {
    VerifyToken,
    ReceivedMessage
}

第二个文件是whatsapService,我使用令牌与API建立连接,并且我还发送当我收到hello时要发送的消息的格式,例如...

const https = require("https");
function SendMessageWhatsApp(textResponse, number){
    const data = JSON.stringify({
        "messaging_product": "whatsapp",    
        "recipient_type": "individual",
        "to": number,
        "type": "text",
        "text": {
            "preview_url": false,
            "body": textResponse
        }
    });

    const options = {
        host:"graph.facebook.com",
        path:"/v15.0/1119744*************/messages",
        method:"POST",
        body:data,
        headers: {
            "Content-Type":"application/json",
            Authorization:"Bearer EAAWNbICfuWEBAK5ObPbD******************************************************"
        }
    };
    const req = https.request(options, res => {
        res.on("data", d=> {
            process.stdout.write(d);
        });
    });

    req.on("error", error => {
        console.error(error);
    });

    req.write(data);
    req.end();
}

module.exports = {
    SendMessageWhatsApp
};

然后,我声明get(检查令牌)和post(接收和回复消息)方法的路由:

const expres = require("express");
const router = expres.Router();
const whatsappController = require("../controllers/whatsappControllers");

router
.get("/", whatsappController.VerifyToken)
.post("/", whatsappController.ReceivedMessage)

module.exports = router;

最后但并非最不重要的索引文件,以便代码正确运行:

const express = require("express");
const apiRoute = require("./routes/routes");

const app = express();

const PORT = process.env.PORT || 3000

app.use(express.json());

app.use("/whatsapp", apiRoute);

app.listen(PORT, () => (console.log("El puerto es: " + PORT)));

我应该澄清一下,我用Postman做了测试,它们都很成功,它正确地响应和接收消息,最后我通过将机器人上传到Azure服务来做测试,它工作没有问题,直到它必须回答/复制用户的消息。
当用户与机器人对话时,机器人没有响应,但所有内容都正确地到达服务器,并以200响应进行处理。我附上接收没有问题的证据。

最后,我必须说,在 meta平台中,我已经按照相同平台的规定配置了所有内容,我已经配置了API通过webhook回答消息,所有内容都是正确的,我只是不能让bot正确回答。
机器人程序托管在Azure服务中。

已解决:一些号码有一个问题,与API的WAB在我的国家(阿根廷)的电话号码开始在+54 9 11.问题是9在电话号码,这有一个冲突,在 meta服务器,解决方案退出号码9到这个国家的号码,消息将发送给用户.
