Question

我正尝试从AWS s3获得xml响应，如本文档所述：

https://docs.aws.amazon.com/AmazonS3/latest/API/v2-RESTBucketGET.html

我不确定如何整合这些参数：

GET /?list-type=2 HTTP/1.1
Host: BucketName.s3.amazonaws.com
Date: date
Authorization: authorization string

插入标准AJAX代码的“ open”语句，如下所示：

function httpGetAsync(theUrl, callback)
{
var xmlHttp = new XMLHttpRequest();
xmlHttp.onreadystatechange = function() { 
    if (xmlHttp.readyState == 4 && xmlHttp.status == 200)
        callback(xmlHttp.responseText);
}
xmlHttp.open("GET", theUrl, true); // true for asynchronous 
xmlHttp.send(null);
}

我在想这样的事情：

xmlhttp.open("GET", URL, false);
xmlhttp.setRequestHeader("list-type", "2");
xmlhttp.setRequestHeader("Content-Type", "text/xml");
xmlhttp.setRequestHeader("Date", "00/00/2018");
xmlhttp.setRequestHeader("Authorization", "authorization string");

对如何做到这一点有何见解？

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html

这是AWS Javascript SDK的文档。我不确定您要获取的XML是什么，但是您正在寻找的可能在那里。

var params = {
  Bucket: "examplebucket", 
  Key: "HappyFace.jpg"
 };
 s3.getObject(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
 });

Javascript S3 GET Bucket（列表对象）格式？
