通过Node.js将base64编码的图像上传到Amazon S3

对于仍在努力解决此问题的人们。这是我与本机aws-sdk一起使用的方法。

var AWS = require('aws-sdk');AWS.config.loadFromPath('./s3_config.json');var s3Bucket = new AWS.S3( { params: {Bucket: 'myBucket'} } );

在您的路由器方法中：-ContentType应该设置为图像文件的内容类型

  buf = Buffer.from(req.body.imageBinary.replace(/^data:image/w+;base64,/, ""),'base64')  var data = {    Key: req.body.userId,     Body: buf,    ContentEncoding: 'base64',    ContentType: 'image/jpeg'  };  s3Bucket.putObject(data, function(err, data){      if (err) {         console.log(err);        console.log('Error uploading data: ', data);       } else {        console.log('succesfully uploaded the image!');      }  });

s3_config.json文件是：-

{  "accessKeyId":"xxxxxxxxxxxxxxxx",  "secretAccessKey":"xxxxxxxxxxxxxx",  "region":"us-east-1"}
