我在本地主機上進行了測驗，然后在 s3 上進行了檢查，發現創建了一個新檔案。但是在Lambda上測驗的時候，雖然沒有報錯，但是S3上沒有檔案。s3.upload(params).promise() 的日志也不顯示。
var fs = require('fs');
var AWS = require('aws-sdk');
exports.handler = async (event, context, callback) => {
context.callbackWaitsForEmptyEventLoop = false
try {
AWS.config.update({
accessKeyId: accessKeyId,
secretAccessKey: secretAccessKey
});
var s3 = new AWS.S3();
var path = 'myfile.txt';
var file_buffer = fs.readFileSync(path);
console.log(file_buffer);
var params = {
Bucket: 'bucket-dev',
Key: '2222.txt',
Body: file_buffer
};
console.log("1111");
s3.upload(params).promise()
.then(function(data) {
console.log("Successfully uploaded to");
callback(null, "All Good");
})
.catch(function(err) {
console.error(err, err.stack);
callback(err);
});
console.log("2222");
return context.logStreamName
} catch (err) {
console.log(err);
callback(err);
}
}
謝謝
uj5u.com熱心網友回復：
盡量不要混搭async和callback。這樣的事情可能更接近你想要的......
var fs = require("fs");
var AWS = require("aws-sdk");
exports.handler = async (event, context) => {
AWS.config.update({
accessKeyId,
secretAccessKey,
});
const s3 = new AWS.S3();
const path = "myfile.txt";
const file_buffer = fs.readFileSync(path);
const params = {
Bucket: "bucket-dev",
Key: "2222.txt",
Body: file_buffer,
};
console.log("1111");
const res = await s3.upload(params).promise();
console.log("Successfully uploaded", res);
return "All good";
};
