在Azure blob存储中启用cors

Question

有人可以告诉我如何在Azure blob存储中启用cors吗？我试过以下但是没有用

         ServiceProperties propers = new ServiceProperties();
        CorsRule cr = new CorsRule();
        List<String> allowedHeaders = new ArrayList<String>();
        allowedHeaders.add(CorsHttpMethods.PUT.name());
        allowedHeaders.add(CorsHttpMethods.POST.name());
        allowedHeaders.add(CorsHttpMethods.DELETE.name());
        allowedHeaders.add(CorsHttpMethods.GET.name());
        cr.setAllowedHeaders(allowedHeaders);
        List<String> allowedOrigin = new ArrayList<String>();
        allowedOrigin.add("*");
        cr.setAllowedOrigins(allowedOrigin);
        cr.setMaxAgeInSeconds(600);
        CorsProperties corsprop = new CorsProperties();
        corsprop.getCorsRules().add(cr);

        blobClient.uploadServiceProperties(propers);

这项工作对我来说如下

   private static ServiceProperties getCORS() {
    ServiceProperties propers = new ServiceProperties();
    CorsProperties corsprop = propers.getCors();

    CorsRule cr = new CorsRule();

    List<String> allowedHeaders = new ArrayList<String>();
    allowedHeaders.add("x-ms-*");
    List<String> exposedHeaders = new ArrayList<String>();
    exposedHeaders.add("x-ms-*");

    cr.setAllowedHeaders(allowedHeaders);
    cr.setExposedHeaders(exposedHeaders);
    EnumSet<CorsHttpMethods> allowedMethod = EnumSet.of(CorsHttpMethods.PUT);
    cr.setAllowedMethods(allowedMethod);

    List<String> allowedOrigin = new ArrayList<String>();
    allowedOrigin.add("*");
    cr.setAllowedOrigins(allowedOrigin);
    cr.setMaxAgeInSeconds(600);

    corsprop.getCorsRules().add(cr);

    //corsprop.getCorsRules().add(cr);
    propers.setCors(corsprop);
    return propers;
}

现在我可以使用以下代码进行设置。我可以使用它，当我从Gaurav创建的javascript客户端上传文件时：http://gauravmantri.com/2013/02/16/uploading-large-files-in-windows-azure-blob-storage-using-shared-access-signature-html-and-javascript/

        CloudStorageAccount storageAccount;

        storageAccount = CloudStorageAccount.parse(storageConnectionString);

        CloudBlobClient blobClient = storageAccount.createCloudBlobClient();

        CloudBlobContainer container = blobClient.getContainerReference(containerName);


        ServiceProperties propers = getCORS();

        SharedAccessBlobPolicy policy = createPolicy();

        blobClient.uploadServiceProperties(propers);
