Apex class which uploads document error: The MAC signature found in the HTTP request '' is not the same as any computed signature

Question

我想使用 Apex 代码将文档上传到 Azure Blob。

我有以下 Apex class 将文档上传到 Azure 但出现错误

"The MAC signature found in the HTTP request '' is not the same as any computed signature".

我不确定我在哪里弄乱了 HTTP 身份验证 header。我确实使用了 https://whosebug.com.

中的代码

public class AzureService {

    private String storageKey;
    private String storageName;
    private String storageContainer;
    private String storageUrl;
    private String blobName;
    private String requestURL;
    private String fileLength;
    private String formattedDate ;
    private String fileType;
    private String fileName;


    private final string DATEFORMAT = 'EEE, dd MMM yyyy HH:mm:ss z';
    private final string VERSION = '2015-12-11';
    private final string BLOB_TYPE = 'BlockBlob';


    public Boolean uploadBlob( Blob fileBody, Integer intFileLength, String strFileType, String strFileName)
    {

        Boolean isUploaded= false;
        this.fileName = EncodingUtil.urlEncode(strFileName, 'UTF-8');
        this.fileType = strFileType;
        this.storageName = 'STORAGE_ACCOUNT';
        this.storageContainer = 'CONTAINER_NAME';
        this.storageKey = 'ACCESS_KEY';
        this.storageUrl ='https://STORAGE_ACCOUNT.blob.core.windows.net';

        this.blobName = '/'+storageName+'/'+storageContainer+'/'+fileName;
        System.debug('blobName--->'+blobName);
        this.requestURL = storageUrl+'/'+storageContainer+'/'+fileName;
        System.debug('requestURL--->'+requestURL);

        this.fileLength = String.valueof(intFileLength);

        String strSharedKey = getBlobSharedKey();

        try
        {
            this.uploadBlob(fileBody, strSharedKey);
            isUploaded = true;

        }catch(Exception exp)
        {
            System.debug('Exception occur while uploading the Blob-->'+exp.getMessage());
            isUploaded = false;
        }

        return isUploaded;
    }


    public String getBlobSharedKey()
    {
        System.debug('getBlobSharedKey--->Start');
        String sharedKey;
        String signature;
        Datetime dt = Datetime.now();

        this.formattedDate = dt.formatGMT(DATEFORMAT);
        String stringToSign = 'PUT\n\n\n'+fileLength+'\n\n'+fileType+'\n\n\n\n\n\n\nx-ms-blob-type:BlockBlob\nx-ms-date:'+formattedDate+'\nx-ms-version:2015-12-11\n'+blobName;

        System.debug('stringToSign--->'+stringToSign);

        Blob unicodeKey = EncodingUtil.base64Decode(storageKey);
        Blob data = Crypto.generateMac('hmacSHA256', Blob.valueOf(stringToSign), unicodeKey);
        signature = EncodingUtil.base64Encode(data);

        sharedKey = 'SharedKey '+storageName+':' + signature;
        return sharedKey;
    }

   public void uploadBlob(Blob fileBody, String sharedKey)
   {
       HttpRequest req = new HttpRequest();


       req.setMethod('PUT');

       req.setHeader('x-ms-blob-type', BLOB_TYPE);
       req.setHeader('x-ms-version', VERSION);
       req.setHeader('x-ms-date', formattedDate);
       req.setHeader('Authorization', sharedKey);
       req.setHeader('Content-Type', fileType);
       req.setHeader('Content-Length', fileLength);

       req.setEndpoint(this.requestURL);

       req.setBodyAsBlob(fileBody);

       Http http = new Http();
       HTTPResponse res = http.send(req);
       // in the response body you have your blob
       System.debug('Response Body--->'+res.getBody());
       System.debug('Status--->'+res.getStatus());

   }

}

感谢您Gaurav Mantri的建议。将其转化为答案以帮助其他社区成员。

请检查 Azure 存储服务用于 stringToSign 的值。将其与您正在计算的 stringToSign 的值进行比较。他们两个应该完全匹配
