我正在使用twilio,当调用我的twilio号码时它会调用webhook,我使用lambda函数作为webhook,
twilio期待来自webhook的xml(以前称为twiml)响应,我无法从lambda函数发送xml响应
我正在使用无服务器框架
这是我的代码
功能:
module.exports.voice = (event, context, callback) => {
console.log("event", JSON.stringify(event))
var twiml = new VoiceResponse();
twiml.say({ voice: 'alice' }, 'Hello, What type of podcast would you like to listen? ');
twiml.say({ voice: 'alice' }, 'Please record your response after the beep. Press any key to finish.');
twiml.record({
transcribe: true,
transcribeCallback: '/voice/transcribe',
maxLength: 10
});
console.log("xml: ", twiml.toString())
context.succeed({
body: twiml.toString()
});
};

如果我在代码中犯了一些错误,请告诉我

最佳答案 你不需要乱用serverless.yml.这是一个简单的方法:
在serverless.yml中……
functions:
voice:
handler: handler.voice
events:
- http:
path: voice
method: post
(不需要响应,标题,内容类型,模板和statusCodes)
然后,您可以在函数中设置statusCode和Content-Type.
所以删除这部分……
context.succeed({
body: twiml.toString()
});
…并将其替换为:
const response = {
statusCode: 200,
headers: {
'Content-Type': 'text/xml',
},
body: twiml.toString(),
};
callback(null, response);
Lambda代理集成(默认情况下)将其组合成适当的响应.
我个人觉得这种方式更简单,更易读.
