查询泛微OA流程状态的代码

在泛微OA（Office Automation System）中，查询流程状态通常需要通过其提供的API或者Web服务来进行。具体的代码会依赖于你使用的开发语言、OA系统的版本以及你对系统API的理解。以下是一个简单的示例，假设你使用的是Java，并且已经获取了OA系统的访问凭证：

import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class OAProcessStatusQuery {
    private static final String URL = "http://your-oa-server/process-instance/{processInstanceId}";

    public static void main(String[] args) throws Exception {
        CloseableHttpClient httpClient = HttpClients.createDefault();
        try {
            HttpGet request = new HttpGet(URL.replace("{processInstanceId}", "12345")); // replace with your process instance ID
            request.addHeader("Authorization", "Bearer your_access_token"); // replace with your API token

            CloseableHttpResponse response = httpClient.execute(request);
            try {
                if (response.getStatusLine().getStatusCode() == 200) {
                    HttpEntity entity = response.getEntity();
                    String statusJson = EntityUtils.toString(entity);
                    // 解析json并获取流程状态
                    JSONObject workflowStatus = new JSONObject(statusJson);
                    String status = workflowStatus.getString("status");
                    System.out.println("流程状态: " + status);
                } else {
                    System.err.println("请求失败, 状态码: " + response.getStatusLine());
                }
            } finally {
                response.close();
            }
        } finally {
            httpClient.close();
        }
    }
}

请注意，这段代码只是一个基本的示例，实际应用中可能还需要处理异常、错误解析以及更复杂的权限验证。另外，你需要替换URL中的`{processInstanceId}`和`your_access_token`为实际的流程实例ID和你的API令牌。
