Code NodeJS: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),
});
}
});
}
I resolved this problem: I sending file using base64 to API Gateway and lambda functions setup parameter "ContentEncoding. 'base64'".我解决了这个问题:我使用 base64 将文件发送到 API 网关和 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"
};
