Question

我正在尝试批量删除与我的数据库中的一个特定博客记录相关联的s3对象，但是我还想知道如何将数组传递给我的params对象以便在{{ 1}}方法，但我对这个错误持谨慎态度：s3.deleteObjects。我觉得这可能与在流程中的某个时刻没有循环或者传递给我的Check with error message InvalidParameterType: Expected params.Delete.Objects[0].Key to be a string数组的值的格式有关。

这是我的路由：

s3File

以下是.delete(function(req, res){ models.File.findAll({ where: { blogId: blog.blogId } }).then(function(file){ var s3Files = []; function s3Key(link){ var parsedUrl = url.parse(link); var fileName = parsedUrl.path.substring(1); return fileName; } for(var k in file){ console.log('Here are each files ' + file[k].fileName); s3Files.push(s3Key(file[k].fileName)); } console.log('Here are the s3Files ' + s3Files); //GOTTEN TO THIS POINT WITHOUT AN ERROR aws.config.update({accessKeyId: process.env.AWS_ACCESS_KEY, secretAccessKey: process.env.AWS_SECRET_KEY, region: process.env.AWS_REGION}); //var awsKeyPath = s3Key(file.fileName); var s3 = new aws.S3(); var options = { Bucket: process.env.AWS_BUCKET, Delete: { Objects: [{ Key: s3Files }], }, }; s3.deleteObjects(options, function(err, data){ if(data){ console.log("File successfully deleted"); } else { console.log("Check with error message " + err); } }); });的输出：

console.log('Here are each files ' + file[k].fileName);

以下是Here are each files https://local-bucket.s3.amazonaws.com/1/2017-02-12/screen_shot_2017-02-01_at_8_25_03_pm.png Here are each files https://local-bucket.s3.amazonaws.com/1/2017-02-13/test.xlsx Here are each files https://local-bucket.s3.amazonaws.com/1/2017-02-13/screen-shot-2017-02-08-at-8.23.37-pm.png的输出：

console.log('Here are the s3Files ' + s3Files);

以下是错误消息：

Here are the s3Files 1/2017-02-12/screen_shot_2017-02-01_at_8_25_03_pm.png,1/2017-02-13/test.xlsx,1/2017-02-13/screen-shot-2017-02-08-at-8.23.37-pm.png

Answer 1

键应该是一个字符串。您应该使用Object to Objects数组使用此代码：

var objects = [];
for(var k in file){
  objects.push({Key : file[k].fileName});
}
var options = {
  Bucket: process.env.AWS_BUCKET,
  Delete: {
    Objects: objects
  }
};

Answer 2

将数组更改为对象

const objects = [
  {Key: 'image1.jpg'},
  {Key: 'image2.jpg'}
]

向列表中添加新项目

for(var k in file){
  objects.push({Key : file[k].fileName});
}

将数组设置为参数中的对象值

const options = {
    Bucket: process.env.BUCKET,
    Delete: {
        Objects: objects,
        Quiet: false
    }
};

现在删除对象

 s3.deleteObjects(options, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
});
