Question

大家好我试图使用节点js从我的s3存储桶中删除对象这里是我的服务器端脚本将执行

var aws = require('aws-sdk');
var s33 = new aws.S3();
aws.config.update({
    accessKeyId: "xxxxxxxxxxxxxxxxxxxxxx",
    secretAccessKey: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    bucket : "xxxxxxxxxxxx",
    region: "us-east-1"
});

app.post('/deleteObj',function(req, res) {
        var params = {
          Bucket: 'xxxxxxxxxxxxx',
          Delete: { // required
            Objects: [ // required
              {
                Key: 'some-key' // required
              },
              /*{
                Key: 'sample-image--10.jpg'
              }*/
            ],
          },
        };

        s33.deleteObjects(params, function(err, data) {
          if (err) console.log(err, err.stack); // an error occurred
          else     console.log(data);           // successful response
        });

    });

显示错误凭据错误，不应该发生，因为我只能使用这些凭据进行基于浏览器的POST上传。

这是错误日志：

CredentialsError: Missing credentials in config

   { message: 'Could not load credentials from any providers',
     retryable: false,
     time: 2017-11-17T06:43:51.657Z,

这里是桶的cors配置，如果它有帮助，请看看这个：

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
    <AllowedOrigin>http://xxxxxxxxxxxxxxxxxxxxxxxxxxxx</AllowedOrigin>
    <AllowedMethod>POST</AllowedMethod>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
</CORSConfiguration>

让我知道你对此的看法。

-Thanks

当您使用AWS API时，不涉及CORS。

您的问题是您在创建S3客户端后分配凭据。

将您的代码更改为：

var aws = require('aws-sdk');

aws.config.update({
    accessKeyId: "xxxxxxxxxxxxxxxxxxxxxx",
    secretAccessKey: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    bucket : "xxxxxxxxxxxx",
    region: "us-east-1"
});

var s33 = new aws.S3();

s3 bucket删除缺少凭据错误
