亚马逊 s3 授权标头无效

Question

我在使用 amazon s3 身份验证时遇到问题。

并且错误指向亚马逊授权。 它说。

AWS 授权标头无效。预期的 AwsAccessKeyId：签名

这里是我的代码：

   // set default values for optional params first
    bucket = bucket || null;
    path = path || '/';
    query = query || [];
    data = data || null;
    headers = headers || [];
    amazon = amazon || null;

    //get host - bucket1.s3.amazonaws.com
    var host    = this._getHost(bucket);
    //get url - http://bucket1.s3.amazonaws.com/some/path
    var url     = this._getUrl(host, path, query);
    //get path - /bucket1/some/path
    var path    = this._getPath(bucket, path);

    hashed().ksort(amazon);

    // initiatialize variables needed
    var restHeaders = amazonHeaders = [];

    headers.Host = host;
    headers.Date = time().toDate(Date.now(), 'D, d M Y H:i:s T', true);

    for (var header in amazon) {
        restHeaders.push(header+': '+amazon[header]);
        amazonHeaders.push(header.toLowerCase()+':'+amazon[header]);
    }

    for (var header in headers) {
        restHeaders.push(header+': '+headers[header]);
    }

    amazonHeaders = '\n'+amazonHeaders.join('\n');

    if(!amazonHeaders.trim()) {
        amazonHeaders = null;
    }

    if(!(typeof headers['Content-MD5'] !== 'undefined')) {
        headers['Content-MD5'] = null;
    }

    if(!(typeof headers['Content-type'] !== 'undefined')) {
        headers['Content-Type'] = null;
    }

    //get signature
    var signature = [
        action,
        headers['Content-MD5'], 
        headers['Content-Type'],
        headers['Date']+amazonHeaders,
        path];

    signature = signature.join('\n');
    if(headers.Host == 'cloudfront.amazonaws.com') {
        signature = headers.Date;
    }

    restHeaders.push('Host: '+host);
    restHeaders.push('Date: '+headers.Date);
    restHeaders.push('Authorization: '+this._getSignature(signature));

请帮助我，我永远坚持这一点。

对于大多数传统用例和应用程序，您不应该自己编写代码来计算签名。您应该为您的编程语言使用 AWS 提供的 SDK

见http://aws.amazon.com/tools

这些 SDK 提供更高级别的功能，更易于使用。它们管理许多低级细节，例如连接管理、错误处理和...签名！
