我正在使用React Native为Andrioid和iOS构建移动应用程序。
基于不存在支持Azure Storage API for React Native的框架的情况（所有框架都是React Native中不存在的必需浏览器），
我使用REST API与Azure存储交互，它工作得很好，例如列表容器、列表blob、获取blob和放置blob。
为了上传大文件，我尝试使用相同的mechanizm为'put block' api（如下所述：https://learn.microsoft.com/en-us/rest/api/storageservices/put-block）未成功，失败，错误代码为403。
我将感谢你的帮助。
谢谢你。
我的代码上传单个块：

private createAuthorizationHeader(canonicalizedString: string) {
  const str = CryptoJS.HmacSHA256(canonicalizedString, CryptoJS.enc.Base64.parse(this.config.accountKey));
  const sig = CryptoJS.enc.Base64.stringify(str);
  const authorizationHeader = `SharedKey ${this.config.accountName}:${sig}`;
  return authorizationHeader;
}
  

  
async putBlockBlob(containerName: str, blobPath: str, blobContent: str, blockIndex: number,) {
  const requestMethod = 'PUT';
    
  const urlPath = `${containerName}/${blobPath}`;
