java SSE如何携带digest auth

在Java中,可以通过HttpURLConnection来发送带有Digest Auth的SSE请求。首先需要创建一个HttpURLConnection对象,并设置请求的URL、请求方法、以及请求头中的Authorization字段。Authorization字段需要包含Digest Auth的凭证信息,可以使用Java的MessageDigest类来计算请求消息的摘要值,并将摘要值与用户名、密码等信息一起编码成Base64字符串,然后放入Authorization字段中。以下是示例代码:
```java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Base64;
public class SSEWithDigestAuth {
public static void main(String[] args) throws IOException, NoSuchAlgorithmException {
String username = "your_username";
String password = "your_password";
String url = "your_sse_url";
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
connection.setRequestMethod("GET");
// Calculate digest
MessageDigest md = MessageDigest.getInstance("MD5");
String ha1 = username + ":" + "realm" + ":" + password;
byte[] ha1Bytes = md.digest(ha1.getBytes());
String ha2 = "GET" + ":" + url;
byte[] ha2Bytes = md.digest(ha2.getBytes());
String response = ha1Bytes.toString() + ":" + "nonce" + ":" + "00000001" + ":" + "cnonce" + ":" + "qop" + ":" + ha2Bytes.toString();
byte[] responseBytes = md.digest(response.getBytes());
String digest = Base64.getEncoder().encodeToString(responseBytes);
// Set Authorization header
String authHeader = "Digest username=\"" + username + "\", realm=\"realm\", nonce=\"nonce\", uri=\"" + url + "\", qop=auth, nc=00000001, cnonce=\"cnonce\", response=\"" + digest + "\"";
connection.setRequestProperty("Authorization", authHeader);
// Send request
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
reader.close();
}
}
```
在上面的示例代码中,我们使用了Java的MessageDigest类来计算请求消息的md5摘要值,然后将摘要值与用户名、密码等信息编码成Base64字符串,并放入Authorization字段中。注意,这里只是一个简单的示例,实际使用中需要根据具体的情况进行调整和完善。
