使用前提与环境准备:服务开通与购买
Step By Step
1.参考API文档与公共参数文档获取相应请求参数
2.添加pom依赖
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-core</artifactId>
<version>4.5.25</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-nlp-automl</artifactId>
<version>0.0.5</version>
</dependency>
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>aliyun-java-sdk-alinlp</artifactId>
<version>1.0.16</version>
</dependency>
2.Code Sample
import com.aliyuncs.CommonRequest;
import com.aliyuncs.CommonResponse;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.profile.DefaultProfile;
//自然语言处理之情感分析(通用) common request 调用示例
public class AliNLP3 {
public static void main(String[] args) {
// 创建DefaultAcsClient实例并初始化
DefaultProfile defaultProfile = DefaultProfile.getProfile(
"cn-hangzhou",
"XXXXXXXXXX",
"XXXXXXXXXX");
IAcsClient client = new DefaultAcsClient(defaultProfile);
// 创建API请求并设置参数
CommonRequest request = new CommonRequest();
// domain和version是固定值
request.setDomain("alinlp.cn-hangzhou.aliyuncs.com");
request.setVersion("2020-06-29");
//action name可以在API文档里查到
request.setSysAction("GetSaChGeneral");//注意此行如果版本依赖core是3.5.0会报错
//put的参数可以在API文档查看到
request.putQueryParameter("ServiceCode", "alinlp");
request.putQueryParameter("Text", "服务很好");
try {
CommonResponse response = client.getCommonResponse(request);
System.out.println(response.getData());
} catch (ServerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
3.测试结果
{"RequestId":"0C07B298-FC89-5314-9D4E-FA3FC48CD9DE","Data":"{\"result\":{\"positive_prob\":0.9963,\"sentiment\":\"正面\",\"neutral_prob\":0.0001,\"negative_prob\":0.0036},\"success\":true,\"tracerId\":\"e6bfb6c9a9a6392a4ff81f7dc0a22abc\"}"}
