我正在尝试使用Lambda将文件上传到S3方式API GateWay,我正在使用下面的代码,文件被发送到S3,例如显示图像'test_using_postman.png'和's3_file.png',但是当我尝试打开后,显示消息文件已损坏,例如show'open_file_with_problem.png'。图片在下面。
有人知道发生了什么吗?
谢谢!

S3文件:https://drive.google.com/open?id=1b1_CmIhzfc8mQj_rwCK6Xy30gzoP6HcK
打开文件时出现问题:https://drive.google.com/open?id=1o54rLB9wWF1KxdUOkq3xAGVET7UWoqgf
代码NodeJS:
const crypto = require('crypto');
var AWS = require('aws-sdk');
AWS.config.update({region: 'us-east-1'});
module.exports.arquivo_upload = (event, context, callback) => {
let BUCKET_NAME = 'XXXXX';
let fileContent = event.body;
let filePath = 'upload/';
let fileName = crypto.createHash('md5').update('niby_'+Date.now()).digest("hex");
s3 = new AWS.S3({apiVersion: '2006-03-01'});
var uploadParams = {
Bucket: BUCKET_NAME,
Key: filePath+fileName+'.png',
Body: fileContent,
ContentType: "image/png"
};
s3.upload(uploadParams, function (err, data) {
if (err) {
console.error(err);
callback(null,{
statusCode:400,
body: JSON.stringify(err),
});
} if (data) {
//TODO: Call other api to save file name
console.info(data.Location);
callback(null,{
statusCode:200,
body: JSON.stringify(data.Location),
});
}
});
}

我解决了这个问题!我使用base64将文件发送到API Gateway和lambda函数设置参数“ ContentEncoding:'base64'”。
var uploadParams = {
Bucket: config.s3.bucket_name,
Key: config.s3.file_path+fileName+obj.extension,
Body: buf,
ContentEncoding: 'base64',
ContentType: obj.content_type,
ACL: "public-read"
};
