[英]Uploading Image from AWS Lambda to S3 via API Gateway in Binary format
我的Lambda在請求正文( event.body
)中從我的用戶接收圖像的二進制數據。
我嘗試將其正確上傳到S3,但是下載時,圖像已損壞/無法打開。
我還需要將上傳圖像的URl返回給用戶。
請幫忙!
module.exports.uploadImage = (event, context, callback) => {
var buf = new Buffer(new Buffer(event.body).toString('base64').replace(/^data:image\/\w+;base64,/, ""),'base64');
var data = {
Key: Date.now()+"",
Body: buf,
ContentEncoding: 'base64',
ContentType: 'image/png',
ACL: 'public-read'
};
s3Bucket.putObject(data, function(err, data){
if (err) {
console.log(err);
console.log('Error uploading data: ', data);
} else {
console.log('succesfully uploaded the image!');
}
callback(null,data);
});
};
您可以將圖像作為節點Buffer上載到S3。 SDK為您完成轉換。
const AWS = require("aws-sdk");
var s3 = new AWS.S3();
module.exports.handler = (event, context, callback) => {
var buf = Buffer.from(event.body.replace(/^data:image\/\w+;base64,/, ""),"base64");
var data = {
Bucket: "sample-bucket",
Key: Date.now()+"",
Body: buf,
ContentType: 'image/png',
ACL: 'public-read'
};
s3.putObject(data, function(err, data){
if (err) {
console.log(err);
console.log('Error uploading data: ', data);
} else {
console.log('succesfully uploaded the image!');
}
callback(null,data);
});
};
