Java azure rest api文件创建。验证请求失败。格式正确，包括签名。响应代码：403此错误

我相信您出现此错误的原因是因为您在请求头中使用

application/octet stream

值指定

Content-Type

，而不是在

stringToSign

中。请将您的

stringToSign

更改为类似以下内容：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.TimeZone;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import com.microsoft.azure.storage.core.Base64;


public class TestCloudStorage {
private static final String account = "account-name";
private static final String key = "key";


 public static void main(String args[]) throws Exception {
  createFile();
 }


 public static void createFile() throws Exception {
  System.setProperty("sun.net.http.allowRestrictedHeaders", "true");
  String urlString = "https://" + account + ".file.core.windows.net/myfileshare/mydirectory/myfile";
  System.setProperty("https.proxyHost", "proxy");
  System.setProperty("https.proxyPort", "8080");
  HttpURLConnection connection = (HttpURLConnection)(new URL(urlString)).openConnection();
  getFileRq(connection, account, key);
  connection.connect();
  System.out.println("Response message : " + connection.getResponseMessage());
  System.out.println("Response code : " + connection.getResponseCode());
  BufferedReader br = null;



  if (connection.getResponseCode() != 200 && connection.getResponseCode() != 201) {
   br = new BufferedReader(new InputStreamReader((connection.getErrorStream())));
  } 

  else {
   br = new BufferedReader(new InputStreamReader((connection.getInputStream())));
  }
  System.out.println("Response body : " + br.readLine());
 }



 public static void getFileRq(HttpURLConnection request, String account, String key) throws Exception {
  SimpleDateFormat fmt = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss");
  fmt.setTimeZone(TimeZone.getTimeZone("GMT"));
  String date = fmt.format(Calendar.getInstance().getTime()) + " GMT";
  String stringToSign = "PUT" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\nx-ms-content-length:1024" + "\nx-ms-date:" + date + "\nx-ms-type:file" + "\nx-ms-version:" + "2015-02-21" + +"/" + account + request.getURL().getPath();
  System.out.println("stringToSign : " + stringToSign);
  String auth = getAuthenticationString(stringToSign);
  System.out.println(auth);
  request.setRequestMethod("PUT");
  request.setRequestProperty("x-ms-version", "2015-02-21");
  request.setRequestProperty("x-ms-date", date);
  request.setRequestProperty("Content-Type", "application/octet-stream");
  request.setRequestProperty("x-ms-content-length", "1024");
  request.setRequestProperty("Authorization", auth);
  request.setRequestProperty("x-ms-type", "file");
  request.setRequestProperty("Content-Length", "0");
 }


 private static String getAuthenticationString(String stringToSign) throws Exception {
  Mac mac = Mac.getInstance("HmacSHA256");
  mac.init(new SecretKeySpec(Base64.decode(key), "HmacSHA256"));
  String authKey = new String(Base64.encode(mac.doFinal(stringToSign.getBytes("UTF-8"))));
  String auth = "SharedKey " + account + ":" + authKey;
  return auth;
 }
}

或者您可以从请求头中删除

内容类型

，因为默认情况下，内容类型为

应用程序/octet流

更新

我还注意到

2015-02-21

（x-ms-version的值）之后缺少一个新行字符。你能补充一下吗

String stringToSign = "PUT" + "\n" + "\n" + "\n" + "\n" + "\n" + "application/octet-stream\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\n" + "\nx-ms-content-length:1024" + "\nx-ms-date:" + date + "\nx-ms-type:file" + "\nx-ms-version:" + "2015-02-21" + +"/" + account + request.getURL().getPath();

请花点时间格式化有问题的代码，使其至少可读。我试图格式化代码，但无法在堆栈溢出时格式化代码。@RahiMuzammil我已经为您完成了！下一次，请尝试将格式化代码作为不可读代码发布，这对于社区成员来说非常难阅读和解决。请看这里，为了您的耐心和花时间格式化代码，您可以如何@MdFaridUddinKiron BIG+1@为了社区的利益，GauravMantri有时需要耐心。我帮助新会员。谢谢你的灵感。请编辑你的问题并加入你上次尝试的代码。另外，请打印

stringToSign

的输出。还有一件事：当您收到错误时，将错误响应流读取为字符串。这将有更详细的错误消息。请在你的问题中也包括这一点。但我已经做了修改。你在说什么？您应该能够编辑您的问题。只需点击问题下方的“编辑”链接，用最新代码更新问题，然后保存编辑。
