文心一言接入流程

一、定义文心接口相关的入参、出参类

public class WenXinMsg {
    private String role = "user";
    private String content;

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }
}

import java.util.List;

public class WenXinMsgReq {
    private List<WenXinMsg> messages;

    public List<WenXinMsg> getMessages() {
        return messages;
    }

    public void setMessages(List<WenXinMsg> messages) {
        this.messages = messages;
    }
}

public class WenXinMsgRes {
    private String result;
    private Integer error_code;
    private String error_msg;

    public Integer getError_code() {
        return error_code;
    }

    public void setError_code(Integer error_code) {
        this.error_code = error_code;
    }

    public String getError_msg() {
        return error_msg;
    }

    public void setError_msg(String error_msg) {
        this.error_msg = error_msg;
    }

    public String getResult() {
        return result;
    }

    public void setResult(String result) {
        this.result = result;
    }
}

public class WenXinToken {
    private String access_token;

    public String getAccess_token() {
        return access_token;
    }

    public void setAccess_token(String access_token) {
        this.access_token = access_token;
    }
}

二、编写工具类

import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

import java.util.Map;

import java.util.*;

@Component
public class WenXinUtil {
    private String appID = "";
    private   String apiKey = "";
    private   String secretKey = "";
    @Autowired
    RestTemplateUtil restTemplateUtil;
    public   String aiChat(String input) {
        System.out.println(input);
        String tokenUrl = String.format("https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=%s&client_secret=%s&",apiKey,secretKey);

        if (tokenEntity != null) {
            String accessToken = tokenEntity.getBody().getAccess_token();

        return "";

}

三、编写对外接口

@RequestMapping("/wenxin")
@RestController

public class WenXinController {
    @Autowired
    WenXinUtil wenXinUtil;
    @PostMapping("/chat")
    @ResponseBody
    public String introduce(@RequestBody String input) {
        String aiMsg = wenXinUtil.aiChat(input);
        return aiMsg;
    }
}
