从REST客户端使用AZURE表存储服务时，如何解决指定的资源不存在错误

Question

使用Azure存储表REST服务时面临的问题。 在使用服务（插入实体）时，遇到错误“指定的资源不存在”且响应状态为400时，我的存储帐户中甚至存在资源。

我尝试使用Jersy restful API来使用AZURE Storage Service API。 根据Microsoft documnetation，我尝试使用该服务。 Doc链接： https : //docs.microsoft.com/zh-cn/rest/api/storageservices/authorize-with-shared-key

2）我也尝试了GET操作...在这种情况下，响应返回400：原因= HTTP标头之一的值格式不正确。

3）到那时，POSTMAN也尝试过同样的方法，也面临着与上述相同的反应。

        Client client = ClientBuilder.newClient();
        WebTarget target = client.target("https://" + account + ".table.core.windows.net/mytable");

    }
}

我希望程序需要将实体插入存储表。

ramesh.stringToSign授权的两种格式略有不同。

共享密钥授权：

共享的密钥精简版授权：

您混合使用它们是不正确的。 请参考以下工作代码（我使用了Shared Key Lite授权）：

package rest;

import com.sun.org.apache.xml.internal.security.utils.Base64;
import org.json.JSONObject;

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.TimeZone;

public class InsertTableEntityTest {

    private static final String account = "***";
    private static final String key = "***";

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

        String urlString = "https://" + account + ".table.core.windows.net/jay";
        System.out.println(urlString);

        //prepare for the json body
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("PartitionKey", "mypartitionkey");
        jsonObject.put("RowKey", "myrowkey");

        String jsonStr = jsonObject.toString();
        String encoding = "UTF-8";
        System.out.println(jsonStr);
        byte[] data = jsonStr.getBytes(encoding);

        HttpURLConnection conn = (HttpURLConnection) (new URL(urlString)).openConnection();
        conn.setDoInput(true);
        conn.setDoOutput(true);
        getFileRequest(conn, account, data);
        OutputStream outStream = conn.getOutputStream();

        outStream.write(data);
        outStream.flush();
        outStream.close();
        System.out.println(conn.getResponseCode());
        System.out.println(conn.getResponseMessage());

        BufferedReader br = null;
        if (conn.getResponseCode() != 200) {
            br = new BufferedReader(new InputStreamReader((conn.getErrorStream())));
        } else {
            br = new BufferedReader(new InputStreamReader((conn.getInputStream())));
        }
        System.out.println("Response body : " + br.readLine());
    }

    public static void getFileRequest(HttpURLConnection request, String account, byte[] data) 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 = date + "\n" +
                "/" + account + request.getURL().getPath();

        System.out.println("stringToSign : " + stringToSign);
        String auth = getAuthenticationString(stringToSign);
        System.out.println(auth);
        request.setRequestMethod("POST");
        request.setRequestProperty("x-ms-date", date);
        request.setRequestProperty("x-ms-version", "2013-08-15");
        request.setRequestProperty("Authorization", auth);
        request.setRequestProperty("Content-Length", String.valueOf(data.length));
        request.setRequestProperty("Content-Type", "application/json");
        request.setRequestProperty("Accept", "application/json");
    }

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

插入结果：

顺便说一句，x-ms-version不是可选的（最新的是2018-03-28 ）以支持此格式。 请参阅表服务中的Json格式 。
