使用 C# 中的 PUT 请求将内容写入 Azure 存储上的文件
Write content to a file on azure storage with using PUT request in C#
我正在尝试向 Azure 存储文件发出放置请求，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 但我收到 403 错误响应。我在 .net 中创建了一个基本的控制台应用程序。
我的页眉是：
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);
我得到异常的行是粗体格式。
HttpWebResponse response = null;
response = (HttpWebResponse)request.GetResponse();
string returnString = response.StatusCode.ToString();
任何人都可以帮我解决这个问题，或者指导我如何在不使用 azure 客户端的情况下将内容写入 azure 存储上的简单文件 API。

使用Put Range上传内容到azure文件时，可以按照下面的代码（我假设你已经在azure文件共享上创建了一个文件，它的内容长度是大于正在上传的内容):
static void UploadText()
{
string Account = "xxxx";
string Key = "xxxx";
string FileShare = "test1";
string FileName = "11.txt";
string apiversion = "2019-02-02";
//the string to be uploaded to azure file, note that the length of the uploaded string should less than the azure file length
string upload_text = "bbbbbbbbbbbbbbbbbbbbbbbb.";
Console.WriteLine("the string length: " + upload_text.Length);
DateTime dt = DateTime.UtcNow;
string StringToSign = String.Format("PUT\n"
+ "\n" // content encoding
+ "\n" // content language
+ upload_text.Length + "\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"//+ "bytes=0-" + (upload_text.Length - 1) + "\n" // range
+"x-ms-date:" + dt.ToString("R") + "\nx-ms-range:bytes=0-"+(upload_text.Length-1) + "\nx-ms-version:" + apiversion + "\nx-ms-write:update\n" // headers
+ "/{0}/{1}/{2}\ncomp:range", Account, FileShare, FileName);
string auth = SignThis(StringToSign, Key, Account);
string method = "PUT";
string urlPath = string.Format("https://{0}.file.core.windows.net/{1}/{2}?comp=range", Account, FileShare,FileName);
Uri uri = new Uri(urlPath);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = method;
request.ContentLength = upload_text.Length;
request.Headers.Add("x-ms-range", "bytes=0-"+(upload_text.Length-1));
request.Headers.Add("x-ms-write", "update");
request.Headers.Add("x-ms-date", dt.ToString("R"));
request.Headers.Add("x-ms-version", apiversion);
request.Headers.Add("Authorization", auth);
//request.Headers.Add("Content-Length", upload_text.Length.ToString());
var bytes = System.Text.Encoding.ASCII.GetBytes(upload_text);
using (var requestStream = request.GetRequestStream())
{
requestStream.Write(bytes, 0, bytes.Length);
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
//read the content
Console.WriteLine("the response is:" + response.StatusCode);
}
}
private static String SignThis(String StringToSign, string Key, string Account)
{
String signature = string.Empty;
byte[] unicodeKey = Convert.FromBase64String(Key);
using (HMACSHA256 hmacSha256 = new HMACSHA256(unicodeKey))
{
Byte[] dataToHmac = System.Text.Encoding.UTF8.GetBytes(StringToSign);
signature = Convert.ToBase64String(hmacSha256.ComputeHash(dataToHmac));
}
String authorizationHeader = String.Format(
CultureInfo.InvariantCulture,
"{0} {1}:{2}",
"SharedKey",
Account,
signature);
return authorizationHeader;
}
然后在Main()方法中，可以调用UploadText()方法，我这边行得通

without using the azure client API.
为此，您可以直接使用 Azure 文件存储 SDK Microsoft.Azure.Storage.File, version 11.1.1。而且我们总是建议使用 SDK 而不是使用 rest api，因为 SDK 易于使用。
这里是使用这个SDK的例子。
首先，在visual studio中创建一个.NET framework的控制台项目。然后安装这个 nuget 包 Microsoft.Azure.Storage.File, version 11.1.1.
代码：
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();
}
}
}
