springboot+vue项目接入文心一言API

参考文心一言ERNIE-Bot 4.0模型流式和非流式API调用(SpringBoot+OkHttp3+SSE+WebSocket) – autunomy – 博客园 (cnblogs.com)

后端

引入依赖

com.squareup.okhttp3okhttp4.9.3com.alibabafastjson1.2.79

配置okHttp,创建OkHttpConfiguration.java

import okhttp3.ConnectionPool;
import okhttp3.OkHttpClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
import javax.net.ssl.*;
import java.security.*;
import java.security.cert.CertificateException;

import java.util.concurrent.TimeUnit;
 
 
@Configuration
public class OkHttpConfiguration {
 
    @Value("${ok.http.connect-timeout}")
    private Integer connectTimeout;
 
    @Value("${ok.http.read-timeout}")
    private Integer readTimeout;
 
    @Value("${ok.http.write-timeout}")
    private Integer writeTimeout;
 
    @Value("${ok.http.max-idle-connections}")
    private Integer maxIdleConnections;
 
    @Value("${ok.http.keep-alive-duration}")
    private Long keepAliveDuration;
 
    @Bean
    public OkHttpClient okHttpClient() {
        return new OkHttpClient.Builder()
                .sslSocketFactory(sslSocketFactory(), x509TrustManager())
                // 是否开启缓存
                .retryOnConnectionFailure(false)
                .connectionPool(pool())
                .connectTimeout(connectTimeout, TimeUnit.SECONDS)
                .readTimeout(readTimeout, TimeUnit.SECONDS)
                .writeTimeout(writeTimeout,TimeUnit.SECONDS)
                .hostnameVerifier((hostname, session) -> true)
                // 设置代理
//            	.proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("127.0.0.1", 8888)))
                // 拦截器
//                .addInterceptor()
                .build();
    }
 
    @Bean
    public X509TrustManager x509TrustManager() {
        return new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] chain, String authType)
                    throws CertificateException {
            }
            @Override
            public void checkServerTrusted(X509Certificate[] chain, String authType)
                    throws CertificateException {
            }
            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
        };
    }
 
    @Bean
    public SSLSocketFactory sslSocketFactory() {
        try {
            // 信任任何链接
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, new TrustManager[]{x509TrustManager()}, new SecureRandom());
            return sslContext.getSocketFactory();
        } catch (NoSuchAlgorithmException | KeyManagementException e) {
            e.printStackTrace();
        }
        return null;
    }
 
    @Bean
    public ConnectionPool pool() {
        return new ConnectionPool(maxIdleConnections, keepAliveDuration, TimeUnit.SECONDS);
    }
}

配置全局变量，创建WenXinConfig.java

package com.pet.common;
import com.alibaba.fastjson.JSON;
        import com.alibaba.fastjson.JSONObject;
        import lombok.extern.slf4j.Slf4j;
        import okhttp3.*;
        import okhttp3.MediaType;
        import org.springframework.beans.factory.annotation.Value;
        import org.springframework.context.annotation.Configuration;

        import java.io.IOException;
        import java.util.Date;


@Configuration
@Slf4j
public class WenXinConfig {

    @Value("${wenxin.apiKey}")
    public String API_KEY;
    @Value("${wenxin.secretKey}")
    public String SECRET_KEY;
    @Value("${wenxin.accessTokenUrl}")
    public String ACCESS_TOKEN_URL;
    @Value("${wenxin.ERNIE_Bot.URL}")
    public String ERNIE_Bot_4_0_URL;

    //过期时间为30天
    public String ACCESS_TOKEN = null;
    public String REFRESH_TOKEN = null;

    public Date CREATE_TIME = null;//accessToken创建时间

    public Date EXPIRATION_TIME = null;//accessToken到期时间

    /**
     * 获取accessToken
     * @return true表示成功 false表示失败
     */
    public synchronized String flushAccessToken(){
        //判断当前AccessToken是否为空且判断是否过期
        if(ACCESS_TOKEN != null && EXPIRATION_TIME.getTime() > CREATE_TIME.getTime()) return ACCESS_TOKEN;

        //构造请求体 包含请求参数和请求头等信息
        RequestBody body = RequestBody.create(MediaType.parse("application/json"),"");
        Request request = new Request.Builder()
                .url(ACCESS_TOKEN_URL+"?client_id="+API_KEY+"&client_secret="+SECRET_KEY+"&grant_type=client_credentials")
                .method("POST", body)
                .addHeader("Content-Type", "application/json")
                .addHeader("Accept", "application/json")
                .build();
        OkHttpClient HTTP_CLIENT = new OkHttpClient().newBuilder().build();
        String response = null;
        try {
            //请求
            response = HTTP_CLIENT.newCall(request).execute().body().string();
        } catch (IOException e) {
            log.error("ACCESS_TOKEN获取失败");
            return null;
        }

        //刷新令牌以及更新令牌创建时间和过期时间
        JSONObject jsonObject = JSON.parseObject(response);
        ACCESS_TOKEN = jsonObject.getString("access_token");
        REFRESH_TOKEN = jsonObject.getString("refresh_token");
        CREATE_TIME = new Date();
        EXPIRATION_TIME = new Date(Long.parseLong(jsonObject.getString("expires_in")) + CREATE_TIME.getTime());

        return ACCESS_TOKEN;
    }
}

配置application.yml

okhttp:
  connect-timeout: 30 # 连接超时时间，单位通常为秒
  read-timeout: 30 # 读取超时时间，单位通常为秒
  write-timeout: 30 # 写入超时时间，单位通常为秒
  max-idle-connections: 200 # 连接池中整体的空闲连接的最大数量
  keep-alive-duration: 300 # 连接空闲时间最多为多少秒

wenxin:
  apiKey: #你的apikey
  secretKey: #你的secretkey
  accessTokenUrl: https://aip.baidubce.com/oauth/2.0/token
  ERNIE_Bot:
    URL: https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/ernie-lite-8k#改成你用的

创建TestController.java

postman测试

前端创建advice.vue （使用了elment-ui）


    
      获取建议重置

    
      建议: 
      

  

  export default {

          this.$message('请输入需求');
        }else{
          this.loading = true
          this.$axios.post(this.$httpUrl + '/test/ask?question=' + this.question).then(res => {
