当我尝试向我的S3存储桶（Node.js）发送内容时，AWS缺少凭据

尝试对参数进行硬编码，看看是否再次出现错误：

AWS.config.update({    accessKeyId: "YOURKEY",    secretAccessKey: "YOURSECRET",    "region": "sa-east-1"   <- If you want send something to your bucket, you need take off this settings, because the S3 are global. }); // for simplicity. In prod, use loadConfigFromFile, or env variablesvar s3 = new AWS.S3();var params = {    Bucket: 'makersquest',    Key: 'mykey.txt',    Body: "HelloWorld"};s3.putObject(params, function (err, res) {    if (perr) {        console.log("Error uploading data: ", err);    } else {        console.log("Successfully uploaded data to myBucket/myKey");    }});
