Javascript &引用；配置中缺少凭据，如果使用AWS_config_文件，请将AWS_SDK_LOAD_config=1"；尝试执行putObject时出错

我对使用AWS服务非常陌生，对JS整体来说也相对陌生。我正在尝试使用putObject将用户数据从我的网站发送到我的s3存储桶。我希望任何进入该站点的用户都能将其数据发送到bucket。在我网站的HTML中，我有以下JavaScript代码，它创建了一个AWS.S3对象，如下所示：

                AWS.config.update({
                    region: 'us-east-1', 
                    accessKeyID: "MYACCESSKEYID",
                    secretAccessKey: "MYSECRETACCESSKEY"

                });
                var s3 = new AWS.S3();

                var params = {
                    Bucket: "my.test.bucket", 
                    Key: <JSON object containing user info>
                };

                s3.putObject(params, function(err, data) {
                    if (err) console.log(err, err.stack); // an error occurred
                    else     console.log(data);           // successful response
                    /*
                    data = {
                        ETag: "\"6805f2cfc46c0f04559748bb039d69ae\"", 
                        VersionId: "tpf3zF08nBplQK1XLOefGskR7mGDwcDk"
                    }
                    */
                });

AWS.config.update({
地区：'us-east-1'，
accessKeyID:“MYACCESSKEYID”，
secretAccessKey:“我的secretAccessKey”
});
var s3=新的AWS.s3（）；
变量参数={
桶：“我的.测试.桶”，
关键：
};
s3.putObject（参数、函数（错误、数据）{
if（err）console.log（err，err.stack）；//发生错误
else console.log（数据）；//响应成功
/*
数据={
ETag:“6805f2cfc46c0f04559748bb039d69ae”，
版本ID：“tpf3zF08nBplQK1XLOefGskR7mGDwcDk”
}
*/
});

访问密钥ID和相应的秘密访问密钥与IAM用户关联，该IAM用户具有执行putObject以向bucket发送对象所需的权限。我知道这不是一种安全的做事方式，但目前这不是一个问题。当我试图在浏览器中打开HTML文件时，我发现标题中的错误消息出现在浏览器控制台中。以下是出现在浏览器控制台中的完整错误消息：

请让我知道，如果有任何其他信息，我可以提供

编辑：使用AWS CLI，我已经尝试配置我的~/.AWS/config文件，使用accesskeyID、机密访问密钥和我在上面代码中使用的区域

我想，问题是没有实例化的配置对象，您可以尝试通过下面的代码创建配置吗？var config=new AWS.config（{accessKeyId:'AKID'，secretAccessKey:'SECRET'，region:'us-west-2'}）；
