Twilio 不通过 AWS Lambda 实时发送 WhatsApp 消息
Twilio is not sending WhatsApp messages in real time through AWS Lambda
抱歉这么长post，但这只是为了更好地解释，因为英语不是我的母语。
我正在使用 API 网关 + Lambda 通过 POST 请求发送 WhatsApp 消息。
我遇到过这种奇怪的行为。看起来 Twilio 需要在 2 次请求或一段时间后“唤醒”。
我已经输入了从“1000”、“1001”、“1002”到“1018”的输入来测试和更好地理解。
- 当我发出请求 1000 和 1001 时，我在 WhatsApp 上什么也没收到。
- 当我发出请求 1002 时，我收到了 1000 消息。所以我总是落后2条消息。
- 假设我一直持续到 1011（我收到消息直到 1009）。然后我等待大约 3 分钟或更短时间。
- 在请求 1012 中，我在 Postman 中收到“内部服务器错误”。 （有时我收到此错误，有时收到 body 响应，但 WhatsApp 从未将 1012 作为消息发送（阅读下一行以便更好地理解））。
- 但我应该收到消息 1010（因为我落后了 2 条消息），但什么也没发生。循环重新开始，我从未收到响应 1010、1011 或 1012。我应该等到请求 1014 才能开始接收消息。
会发生什么？
这是我的 Lambda 代码
///date is 1000, 1001, 1002, 1003, etc. The numbers I have sent manually to test.
'use strict';
console.log('Trying to send a WhatsApp message...');
exports.handler = async (event) => {
const accountSid = 'ACa-------------';
const authToken = '7e5--------------';
const client = require('twilio')("ACa48----------", "7e5d820---------");
let date = "today";
if (event.queryStringParameters && event.queryStringParameters.date) {
console.log("Input received is: " + event.queryStringParameters.date);
fecha = event.queryStringParameters.date;
}
client.messages
.create({
body: date,
from: 'whatsapp:+1---------',
to: 'whatsapp:+1---------'
})
.then(message => console.log("TWILIO RESPONSE SHOULD BE HERE: " + JSON.stringify(message)))
.done();
let rspbody = date + " is the input";
let responseBody = {
message: rspbody,
input: event
};
let response = {
statusCode: 200,
headers: {
"x-custom-header" : "my custom header value"
},
body: JSON.stringify(responseBody),
"isBase64Encoded": false
};
console.log("response LAMBDA: " + JSON.stringify(response));
return response;
};
这是1012请求（上次连续请求后几分钟后发送的）的相关API网关CloudWatch日志（实际上是与成功请求不同的部分）。所以它永远不会通过 API 网关，所以它不会出现在 Lambda 日志中（我稍后附上）。

请帮忙。如果您需要更多信息，请告诉我。
提前致谢。
此处为 Twilio 开发人员布道师。
我认为这里的问题是您在对 Twilio API 的异步请求完成之前从 Lambda 返回。您最终会收到原始请求，因为 AWS 似乎会在 Lambda 完成时暂停事件循环，然后在新的 Lambda 再次启动时恢复它。
我相信你可以通过在调用 Twilio API 之前添加 await 关键字来解决这个问题 API。
await client.messages
.create({
body: date,
from: "whatsapp:+1---------",
to: "whatsapp:+1---------",
})
.then((message) =>
console.log("TWILIO RESPONSE SHOULD BE HERE: " + JSON.stringify(message))
)
您也应该在 API 调用周围添加一个 try/catch，这样您就可以处理 API 错误。
这应该可以解决 。
抱歉这么长post，但这只是为了更好地解释，因为英语不是我的母语。
我正在使用 API 网关 + Lambda 通过 POST 请求发送 WhatsApp 消息。
我遇到过这种奇怪的行为。看起来 Twilio 需要在 2 次请求或一段时间后“唤醒”。 我已经输入了从“1000”、“1001”、“1002”到“1018”的输入来测试和更好地理解。
- 当我发出请求 1000 和 1001 时，我在 WhatsApp 上什么也没收到。
- 当我发出请求 1002 时，我收到了 1000 消息。所以我总是落后2条消息。
- 假设我一直持续到 1011（我收到消息直到 1009）。然后我等待大约 3 分钟或更短时间。
- 在请求 1012 中，我在 Postman 中收到“内部服务器错误”。 （有时我收到此错误，有时收到 body 响应，但 WhatsApp 从未将 1012 作为消息发送（阅读下一行以便更好地理解））。
- 但我应该收到消息 1010（因为我落后了 2 条消息），但什么也没发生。循环重新开始，我从未收到响应 1010、1011 或 1012。我应该等到请求 1014 才能开始接收消息。
会发生什么？
这是我的 Lambda 代码
///date is 1000, 1001, 1002, 1003, etc. The numbers I have sent manually to test.
'use strict';
console.log('Trying to send a WhatsApp message...');
exports.handler = async (event) => {
const accountSid = 'ACa-------------';
const authToken = '7e5--------------';
const client = require('twilio')("ACa48----------", "7e5d820---------");
let date = "today";
if (event.queryStringParameters && event.queryStringParameters.date) {
console.log("Input received is: " + event.queryStringParameters.date);
fecha = event.queryStringParameters.date;
}
client.messages
.create({
body: date,
from: 'whatsapp:+1---------',
to: 'whatsapp:+1---------'
})
.then(message => console.log("TWILIO RESPONSE SHOULD BE HERE: " + JSON.stringify(message)))
.done();
let rspbody = date + " is the input";
let responseBody = {
message: rspbody,
input: event
};
let response = {
statusCode: 200,
headers: {
"x-custom-header" : "my custom header value"
},
body: JSON.stringify(responseBody),
"isBase64Encoded": false
};
console.log("response LAMBDA: " + JSON.stringify(response));
return response;
};
这是1012请求（上次连续请求后几分钟后发送的）的相关API网关CloudWatch日志（实际上是与成功请求不同的部分）。所以它永远不会通过 API 网关，所以它不会出现在 Lambda 日志中（我稍后附上）。

请帮忙。如果您需要更多信息，请告诉我。
提前致谢。
此处为 Twilio 开发人员布道师。
我认为这里的问题是您在对 Twilio API 的异步请求完成之前从 Lambda 返回。您最终会收到原始请求，因为 AWS 似乎会在 Lambda 完成时暂停事件循环，然后在新的 Lambda 再次启动时恢复它。
我相信你可以通过在调用 Twilio API 之前添加 await 关键字来解决这个问题 API。
await client.messages
.create({
body: date,
from: "whatsapp:+1---------",
to: "whatsapp:+1---------",
})
.then((message) =>
console.log("TWILIO RESPONSE SHOULD BE HERE: " + JSON.stringify(message))
)
您也应该在 API 调用周围添加一个 try/catch，这样您就可以处理 API 错误。
这应该可以解决
