azure REST API通信

我当前正在尝试从salesforce检索Azure帐户中可用的列表共享。我试图从以下示例代码中实现该示例：

//私钥：我的帐户的访问密钥
字符串storageKey=私钥；
字符串storageName='accountName'；
Datetime dt=Datetime.now（）；
字符串formattedDate=dt.formattGMT（'EEE，dd-MMM-yyy-HH:mm:ss'）+'GMT'；
调试（'formattedDate--'+formattedDate）；
字符串CanonicalizedHeaders='x-ms-date:'+formattedDate+'\nx ms版本：2016-05-31'；
字符串CanonicalizedResource='/'+storageName+'/\ncomp:list'；
字符串StringToSign='GET\n\n\n\n\n\n\n\n\n\n'+CanonicalizedHeaders+'\n'+CanonicalizedResource；
系统调试（'StringToSign--'+StringToSign）；
Blob temp=EncodingUtil.base64解码（storageKey）；
Blob hmac=加密生成MAC（'HmacSHA256'，Blob.valueOf（StringToSign），温度）//StringToSign
system.debug（'oo-'+EncodingUtil.base64Encode（hmac））；
HttpRequest req=新的HttpRequest（）；
请求setMethod（'GET'）；
//请求setHeader（'content-type'，'application/xml'）；
要求设置标题（'x-ms-version'，'2016-05-31'）；
请求setHeader（'x-ms-date'，formattedDate）；
字符串签名=EncodingUtil.base64Encode（hmac）；
字符串authHeader='SharedKey salesforcestrongaccount'+'：'+签名；
请求setHeader（“授权”，authHeader）；
请求setEndpoint（'https://.file.core.windows.net/?comp=list');
Http=newhttp（）；
HTTPResponse；
res=http.send（req）；
调试（LoggingLevel.INFO，'http.send result status:'+res.getStatus（））；

有什么帮助吗？

正如Gaurav Mantri所说，您的stringToSign有问题。所以你会得到这个错误

正确的共享密钥身份验证如下所示：

StringToSign = VERB + "\n" +  
               Content-Encoding + "\n" +  
               Content-Language + "\n" +  
               Content-Length + "\n" +  
               Content-MD5 + "\n" +  
               Content-Type + "\n" +  
               Date + "\n" +  
               If-Modified-Since + "\n" +  
               If-Match + "\n" +  
               If-None-Match + "\n" +  
               If-Unmodified-Since + "\n" +  
               Range + "\n" +  
               CanonicalizedHeaders +   
               CanonicalizedResource; 

这里我创建了一个测试演示，您可以参考它

列表共享：

        string storageAccount = "storage account";
        string accessKey = "accountkey";
        string resourcePath = "?comp=list";
        string uri = @"https://" + storageAccount + ".file.core.windows.net/" + resourcePath;
        // Web request 
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
        request.Method = "GET";
        request.Headers["x-ms-date"] = DateTime.UtcNow.ToString("R", System.Globalization.CultureInfo.InvariantCulture);
        request.Headers["x-ms-version"] = "2015-02-21";
        String stringToSign = "GET\n"
            + "\n" // content encoding
            + "\n" // content language
            + "\n" // content length
            + "\n" // content md5
            + "\n" // content type
            + "\n" // date
            + "\n" // if modified since
            + "\n" // if match
            + "\n" // if none match
            + "\n" // if unmodified since
            + "\n" // range
            + "x-ms-date:" + request.Headers["x-ms-date"] + "\nx-ms-version:2015-02-21\n" // headers
            + "/" + storageAccount + "/" + "\ncomp:list"; // resources

        System.Security.Cryptography.HMACSHA256 hasher = new System.Security.Cryptography.HMACSHA256(Convert.FromBase64String(accessKey));
        string strAuthorization = "SharedKey " + storageAccount + ":" + System.Convert.ToBase64String(hasher.ComputeHash(System.Text.Encoding.UTF8.GetBytes(stringToSign)));


        request.Headers["Authorization"] = strAuthorization;

        Task<WebResponse> response = request.GetResponseAsync();
        HttpWebResponse responseresult = (HttpWebResponse)response.Result;

        using (System.IO.StreamReader r = new System.IO.StreamReader(responseresult.GetResponseStream()))
        {
            string jsonData = r.ReadToEnd();
            Console.WriteLine(jsonData);
        }

计算

stringToSign

的方式存在问题。请按照此处概述的说明进行操作：然后重试您的请求。您是否可以为此提供任何示例代码。因为我尝试了链接中指定的过程。巴顿·勒克诺：你没有按照那里的指示去做。我快速浏览了一下你的代码，就明白了。我建议您再仔细阅读一下文档。否则，如果您搜索Azure Storage REST API示例，我相信您会找到足够的源代码。我使用SHA256创建了一个MAC密钥，您可以在上面的代码中看到。我有什么遗漏吗？请检查创建stringToSign的文档。这就是你代码中的问题所在。我能知道你是在哪个平台上执行的吗？它是用java写的吗#BrandoI尝试了上述stringtosign格式，但在使用键@Brando ThangThank You#Brando Zhag时出现了相同的错误。Java代码执行得非常完美。但是，当我将逻辑转换为salesforce时，我仍然面临403错误。有什么想法吗？还有一个观察是，我可以通过邮递员应用程序调用azure api。但是，当我在sf中使用相同的键n date时，它抛出403错误。我猜salesforce可能会在您的请求中添加一些自定义头。我建议您可以使用fiddler获取请求，以检查其中是否有任何其他请求头。
