我正在尝试向Azure存储文件发出put请求，我想在其中添加一些简单的内容。我更改了URL并在URL的末尾添加了

？comp=range

，但得到了403错误的响应。我已经在.net中创建了一个基本的控制台应用程序

我的标题是：

 const string requestMethod = "PUT";
            string urlPath = strShareName + "/" + "rahila.csv?comp=range";//+ "?comp=range  HTTP/1.1";
            String canonicalizedResource = String.Format("/{0}/{1}/{2}", StorageAccountName, strShareName, strFileName);
            try
            {
                //GetWebRequest(requestMethod, urlPath, canonicalizedResource, "CreateFile");
                HttpWebRequest request = null;
                try
                {
                    const string type = "file";
                    string MethodType = "CreateFile";
                    const string msVersion = "2015-04-05";
                    String dateInRfc1123Format = DateTime.UtcNow.ToString("R", CultureInfo.InvariantCulture);
                    String canonicalizedHeaders = "";
                    string data = "rahila sted";
                    canonicalizedHeaders = String.Format("x-ms-date:{0}\nx-ms-version:{1}", dateInRfc1123Format, msVersion);
                    if (MethodType == "CreateFile")
                    {
                        canonicalizedHeaders = String.Format("x-ms-content-length:65536\nx-ms-date:{0}\nx-ms-type:file\nx-ms-version:{1}", dateInRfc1123Format, msVersion);
                    }

                    String stringToSign = "";


                    stringToSign = String.Format("{0}\n\n\n\n\n\n\n\n\n\n\n\n{1}\n{2}", requestMethod, canonicalizedHeaders, canonicalizedResource);

                    if (String.IsNullOrEmpty(stringToSign))
                    {
                        throw new ArgumentNullException("canonicalizedString");
                    }

                    String signature;

                    if (String.IsNullOrEmpty(stringToSign))
                    {
                        throw new ArgumentNullException("unsignedString");
                    }

                    if (Convert.FromBase64String(StorageKey) == null)
                    {
                        throw new ArgumentNullException("key");
                    }

                    Byte[] dataToHmac = System.Text.Encoding.UTF8.GetBytes(stringToSign);
                    using (HMACSHA256 hmacSha256 = new HMACSHA256(Convert.FromBase64String(StorageKey)))
                    {
                        signature = Convert.ToBase64String(hmacSha256.ComputeHash(dataToHmac));
                    }


                    String authorizationHeader = String.Format(CultureInfo.InvariantCulture, "{0} {1}:{2}",
                                                               StorageScheme,
                                                               StorageAccountName, signature);
Uri uri = new Uri(FileEndPoint + urlPath);
request = (HttpWebRequest)WebRequest.Create(uri);
if (requestMethod != "Get")
{
    request.ContentLength = data.Length;
}
// string data = "Hello testing";
//int a= ((data.Length) + 1);

request.Method = "PUT";//requestMethod;
request.Headers.Add("x-ms-write", "update");
request.Headers.Add("x-ms-date", dateInRfc1123Format);
request.Headers.Add("x-ms-version", msVersion);
request.Headers.Add("x-ms-range", "bytes=0-65535"); // + ((data.Length) - 1));
request.Headers.Add("Authorization", authorizationHeader);

我得到异常的那一行是粗体格式的

HttpWebResponse response = null;
response = (HttpWebResponse)request.GetResponse();
string returnString = response.StatusCode.ToString();

有谁能帮我解决这个问题，或者指导我如何在不使用azure客户端API的情况下将内容写入azure存储上的简单文件。

更新12/19:

使用将内容上载到azure文件时，您可以遵循以下代码（我假设您已经在azure文件共享上创建了一个文件，并且它的内容长度大于正在上载的内容）：
然后在
Main（）
方法中，您可以调用
UploadText（）
方法，它在我这边工作

旧版：

const string requestMethod = "PUT"; string urlPath = strShareName + "/" + "rahila.csv?comp=range";//+ "?comp=range HTTP/1.1"; String canonicalizedResource = String.Format("/{0}/{1}/{2}", StorageAccountName, strShareName, strFileName); try { //GetWebRequest(requestMethod, urlPath, canonicalizedResource, "CreateFile"); HttpWebRequest request = null; try { const string type = "file"; string MethodType = "CreateFile"; const string msVersion = "2015-04-05"; String dateInRfc1123Format = DateTime.UtcNow.ToString("R", CultureInfo.InvariantCulture); String canonicalizedHeaders = ""; string data = "rahila sted"; canonicalizedHeaders = String.Format("x-ms-date:{0}\nx-ms-version:{1}", dateInRfc1123Format, msVersion); if (MethodType == "CreateFile") { canonicalizedHeaders = String.Format("x-ms-content-length:65536\nx-ms-date:{0}\nx-ms-type:file\nx-ms-version:{1}", dateInRfc1123Format, msVersion); } String stringToSign = ""; stringToSign = String.Format("{0}\n\n\n\n\n\n\n\n\n\n\n\n{1}\n{2}", requestMethod, canonicalizedHeaders, canonicalizedResource); if (String.IsNullOrEmpty(stringToSign)) { throw new ArgumentNullException("canonicalizedString"); } String signature; if (String.IsNullOrEmpty(stringToSign)) { throw new ArgumentNullException("unsignedString"); } if (Convert.FromBase64String(StorageKey) == null) { throw new ArgumentNullException("key"); } Byte[] dataToHmac = System.Text.Encoding.UTF8.GetBytes(stringToSign); using (HMACSHA256 hmacSha256 = new HMACSHA256(Convert.FromBase64String(StorageKey))) { signature = Convert.ToBase64String(hmacSha256.ComputeHash(dataToHmac)); } String authorizationHeader = String.Format(CultureInfo.InvariantCulture, "{0} {1}:{2}", StorageScheme, StorageAccountName, signature); Uri uri = new Uri(FileEndPoint + urlPath); request = (HttpWebRequest)WebRequest.Create(uri); if (requestMethod != "Get") { request.ContentLength = data.Length; } // string data = "Hello testing"; //int a= ((data.Length) + 1); request.Method = "PUT";//requestMethod; request.Headers.Add("x-ms-write", "update"); request.Headers.Add("x-ms-date", dateInRfc1123Format); request.Headers.Add("x-ms-version", msVersion); request.Headers.Add("x-ms-range", "bytes=0-65535"); // + ((data.Length) - 1)); request.Headers.Add("Authorization", authorizationHeader);
指导我如何将内容写入azure存储上的简单文件不使用azure客户端API
为此，您可以直接使用Azure文件存储SDK。我们总是建议使用SDK而不是RESTAPI，因为SDK易于使用
下面是一个使用此SDK的示例
首先，在visual studio中创建.NET framework的控制台项目。然后安装这个nuget包
守则：

using Microsoft.Azure.Storage; using Microsoft.Azure.Storage.Auth; using Microsoft.Azure.Storage.File; using System; namespace AzureFileTest2 { class Program { static void Main(string[] args) { string accountName = "xxx"; string accountKey = "xxx"; CloudStorageAccount storageAccount = new CloudStorageAccount(new StorageCredentials(accountName, accountKey), true); CloudFileClient cloudFileClient = storageAccount.CreateCloudFileClient(); //make sure the file share named test1 exists. CloudFileShare fileShare = cloudFileClient.GetShareReference("test1"); CloudFileDirectory fileDirectory = fileShare.GetRootDirectoryReference(); CloudFile myfile = fileDirectory.GetFileReference("test123.txt"); if (!myfile.Exists()) { //if the file does not exists, then create the file and set the file max size to 100kb. myfile.Create(100 * 1024 * 1024); } //upload text to the file //Besides using UploadText() method to directly upload text, you can also use UploadFromFile() / UploadFromByteArray() / UploadFromStream() methods as per your need. myfile.UploadText("hello, it is using azure storage SDK"); Console.WriteLine("**completed**"); Console.ReadLine(); } } }

如果我是你，我会看你的回答。抛出的异常中有一个
HttpWebResponse
，您可以从中检索主体以查看错误响应是什么。或者，使用像Telerik的Fiddler这样的工具来查看请求和错误响应。我得到的响应是：在System.Net.HttpWebRequest.GetResponse（）处，在NewFilecreateandupload.Program.UpdateContent（字符串strFileName，字符串内容）在C:\Users\abc\source\repos\NewFilecreateandupload\NewFilecreateandupload\Program.cs:第406行，错误是远程服务器返回了一个错误：（403）禁止。这不是响应主体，这是异常。请参阅AuthenticationFailed服务器无法验证请求。确保包括签名在内的授权标头的值格式正确。RequestId:9917d3cd-f01a-006f-03aa-b400f3000000时间：2019-12-17T07:22:38.8281666Z在HTTP请求“+IN5TBFJHF9BILEYFFDGVIQPIDQ/vrqB+PtDogboY=”中找到的MAC签名与任何计算签名都不同。服务器使用以下字符串签名：“PUT x-ms-date:Tue，2019年12月17日07:22:23 GMT x-ms-range:bytes=0-65535 x-ms-type:file x-ms-version:2015-04-05 x-ms-write:update/bc365storage/lables/rahila.csv comp:range”。我被限制不使用Azure文件存储SDK，我们必须使用rest api使其工作，@RahilaSyed，ok，那么在你的帖子中“或者只是指导我如何在不使用azure客户端API的情况下将内容写入azure存储上的简单文件”是什么意思？我将尝试使用RESTAPI进行此操作，并在稍后更新。@RahilaSyed，请参阅更新部分。如果你还有更多的问题，请告诉我。
