通过Postman调用Azure REST API执行查询后无法获取文档

问题说明 #

同一Cosmos DB查询在Azure平台可成功返回符合条件的文档列表，但在Postman中执行后无法检索到任何文档。

var mastKey = postman.getEnvironmentVariable("CosmosDBMasterKey");
console.log("mastKey = " + mastKey);

var today = new Date();
var UTCstring = today.toUTCString();
postman.setEnvironmentVariable("RFC1123time", UTCstring);

var url = request.url.trim(); 

var strippedurl = url.replace(new RegExp('^https?://[^/]+/'),'/');

var strippedparts = strippedurl.split("/");
var truestrippedcount = (strippedparts.length - 1);

var resourceId = "";
var resType = "";

if (truestrippedcount % 2)
{
    resType = strippedparts[truestrippedcount];
   
    if (truestrippedcount > 1)
    {
        var lastPart = strippedurl.lastIndexOf("/");
        resourceId = strippedurl.substring(1,lastPart);
        console.log(resourceId);
    }
}
else 
{
    resType = strippedparts[truestrippedcount - 1];
    strippedurl = strippedurl.substring(1);
    resourceId = strippedurl;
}

var verb = request.method.toLowerCase();

var date = UTCstring.toLowerCase();

var key = CryptoJS.enc.Base64.parse(mastKey);
console.log("key = " + key);

var text = (verb || "").toLowerCase() + "\n" + 
               (resType || "").toLowerCase() + "\n" + 
               (resourceId || "") + "\n" + 
               (date || "").toLowerCase() + "\n" + 
               "" + "\n";
console.log("text = " + text);

// create the signature from build up request text
var signature = CryptoJS.HmacSHA256(text, key);
console.log("sig = " + signature);

// back to base 64 bits
var base64Bits = CryptoJS.enc.Base64.stringify(signature);
console.log("base64bits = " + base64Bits);

// format our authentication token and URI encode it.
var MasterToken = "master";
var TokenVersion = "1.0";
auth = encodeURIComponent("type=" + MasterToken + "&ver=" + TokenVersion + "&sig=" + base64Bits);
console.log("auth = " + auth);

// set our auth token enviornmental variable.
postman.setEnvironmentVariable("authToken", auth);

预期结果 #

执行查询后获取符合条件的文档（对象）列表。
