Question

我在尝试通过node.js客户端使用Segments API时面临授权问题。停止在灌木丛周围，在管理POST请求和通过x-wsse标头授权的部分下方：

var now = new Date();
var options = {
     method: "POST",
     hostname: "api3.omniture.com",
     path: "/admin/1.4/rest/?method=Segments.Get",
     json: true,
     headers: {
            "Content-Type": "application/json",
            "Content-Length" : Buffer.byteLength(JSON.stringify(body)),
            "x-wsse": 'UsernameToken Username="[username]:[company]", PasswordDigest="xxxxxxxxxxxxxxxxxxxxxxxxxx==", Nonce="yyyyyyyyyyyyyyyyyyyyyyyyyy", Created="'+now+'"'
     }
};

如您所见，我尝试复制API Explorer生成的x-wsse，通过Date（）JS类动态指定Created时间戳。节点客户端报告我这个错误：
{＆＃34;错误＆＃34;：＆＃34;错误请求＆＃34;，＆＃34; error_description＆＃34;：＆＃34;无法验证身份验证。＆＃34;，＆＃34; error_uri＆＃34;：空}

我认为x-wsse PasswordDigest和Nonce值也会在每次请求时不断变化，而在这里我将它们静态化。如果这是问题的原因，那么如何在x-wsse头中动态插入这些参数？

非常感谢。

是的，PasswordDigest和Created值也是动态生成的，因为它们基于您生成的值。我不知道node.js是否足以向您展示node.js示例，但这里有一个php示例，我做了一些评论：

$username='user:company';
$secret='12345'; // api shared secret key for the user
// The nonce should be a universally unique value. I use a timestamp based value and prefix with a namespace to help make it unique, because AA request digests have to be unique across everybody everywhere ever
$nonce = 'FOO_'.dechex(time());
// datetime stamp in ISO 8601 date format (e.g. '2004-02-12T15:19:21+00:00')
$nonce_ts = date('c');
// Adobe expects the PasswordDigest to be a concatenated string value of the nonce, datetimestamp, and api key. They expect it to be hashed (sha1) and then base64 encoded
$digest = base64_encode(sha1($nonce.$nonce_ts.$secret));
$server = "https://api.omniture.com";
$path = "/admin/1.4/rest/";
$rc=new SimpleRestClient();
$rc->setOption(CURLOPT_HTTPHEADER, array("X-WSSE: UsernameToken Username=\"$username\", PasswordDigest=\"$digest\", Nonce=\"$nonce\", Created=\"$nonce_ts\""));
