在Primeton BPM写一个token调用脚本示例

在Primeton BPM中调用token的脚本可以使用Java代码来实现。以下是一个基本的示例:
```java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;
public class TokenScript {
public static void main(String[] args) {
String token = getToken("client_id", "client_secret");
System.out.println("Token: " + token);
}
public static String getToken(String clientId, String clientSecret) {
String token = "";
try {
String credentials = clientId + ":" + clientSecret;
String encodedCredentials = Base64.getEncoder().encodeToString(credentials.getBytes());
URL url = new URL("https://oauth2.googleapis.com/token");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Authorization", "Basic " + encodedCredentials);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
String postData = "grant_type=client_credentials";
conn.setDoOutput(true);
conn.getOutputStream().write(postData.getBytes("UTF-8"));
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
String jsonResponse = response.toString();
int startIndex = jsonResponse.indexOf("access_token\":\"") + 15;
int endIndex = jsonResponse.indexOf("\"", startIndex);
token = jsonResponse.substring(startIndex, endIndex);
} catch (Exception e) {
e.printStackTrace();
}
return token;
}
}
```
在这个示例中,我们使用了Google OAuth2服务来获取token。要使用此脚本,您需要将您的client ID和client secret替换为 `client_id` 和 `client_secret` 参数。此外,您需要确保您的Primeton BPM应用程序可以访问该服务。
