请通过这个网址与正确的参数，第一次配置你的SDK。
http://docs.aws.amazon.com/AWSJavaScriptSDK/导游/浏览器configuring.html
你的code这部分导致了错误
AWS.config.update（{
accessKeyId：ACCESSKEY，
secretAccessKey：SecretKey的
}）;
您需要给他们默认为ACCESSKEY和SecretKey的你accessKeyId和secretAccessKey代替。他们应改为按照上面的URL所需的值。
此外，在的getObject PARAMS加上'键'，而不是'关键'。
i am trying to retreive the url of a picture from Amazon s3.
this is the first time i am doing this, so please can anyone help to get this working.
when I run the script below, i get an error: ' Missing required Key in params'
This is what I have so far:
code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="https://sdk.amazonaws.com/js/aws-sdk-2.0.16.min.js"></script>
<script type="text/javascript">
function test1(){
AWS.config.update({
accessKeyId: 'accesskey',
secretAccessKey: 'secretKey'
});
AWS.config.region = 'us-west-2';
var myAWS = new AWS.S3();
myAWS.getObject(
{ Bucket: 'productissues', key: 'carlos.jpg' },
function (error, data) {
if (error != null) {
alert("Failed to retrieve an object: " + error);
} else {
alert("Loaded " + data.ContentLength + " bytes");
// do something with data.body
}
});
}
</script>
</head>
<body>
<button type="button" onclick="test1();" >Click me!</button>
</body>
</html>
Please go through this url for configuring your sdk first with proper parameters.
http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/browser-configuring.html
This part of your code is causing the error
AWS.config.update({
accessKeyId: 'accesskey',
secretAccessKey: 'secretKey'
});
You need to give your accessKeyId and secretAccessKey instead of defaulting them to accesskey and secretkey. They should be replaced with required values following the above url.
Also add 'Key' instead of 'key' in getObject params.
