java调用文心一言API的方法
话不多说，直接上干货：一、首先去官网注册一个账号百度智能云-登录 (baidu.com)，注册完成后等待审核，审核后就可以去控制台操纵啦！
二、根据官网介绍，由于文心一言属于收费产品（也有免费的，但功能限定），因此发起可以充值几块钱，足以做实验用了。我这里用的是“千帆大模型”产品。

三、代码实现过程：
1）调用工具：
package utils;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import okhttp3.*;
import java.io.*;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.HashMap;
public class ChineseGPT {
static final OkHttpClient HTTP_CLIENT = new OkHttpClient().newBuilder().build();
public static void main(String []args) throws IOException{
//1、获取token
String access_token = new ChineseGPT().getWenxinToken();
//2、访问数据
String requestMethod = "POST";
String body = URLEncoder.encode("junshi","UTF-8");//设置要传的信息
String url = "https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/eb-instant?access_token="+access_token;//post请求时格式
//测试：访问聚合数据的地区新闻api
HashMap<String, String> msg = new HashMap<>();
msg.put("role","user");
msg.put("content", "帮我写一篇关于介绍吉林市的小短文，大概100字左右");
ArrayList<HashMap> messages = new ArrayList<>();
messages.add(msg);
HashMap<String, Object> requestBody = new HashMap<>();
requestBody.put("messages", messages);
String outputStr = JSON.toJSONString(requestBody);
JSON json = HttpRequest.httpRequest(url,requestMethod,outputStr,"application/json");
System.out.println(json);
}
public String getWenxinToken() throws IOException {
MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "");
Request request = new Request.Builder()
.url("https://aip.baidubce.com/oauth/2.0/token?client_id=xxxxxxxxxxxxxxxxxx&client_secret=xxxxxxxxxxxxxxxxxx&grant_type=client_credentials") //按官网要求填写你申请的key和相关秘钥
.method("POST", body)
.addHeader("Content-Type", "application/json")
.addHeader("Accept", "application/json")
.build();
Response response = HTTP_CLIENT.newCall(request).execute();
String s = response.body().string();
JSONObject objects = JSONArray.parseObject(s);
String msg = objects.getString("access_token");
System.out.println(msg);
return msg;
}
}
2）哀求工具：
package utils;
import com.alibaba.fastjson.JSONObject;
import javax.net.ssl.HttpsURLConnection;
import java.io.*;
import java.net.ConnectException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;
import java.util.Map;
public class HttpRequest {
/**
* post/GET远程请求接口并得到返回结果
*
* @param requestUrl 请求地址
* @param requestMethod 请求方法post/GET
* @return
*/
public static JSONObject httpRequest(String requestUrl, String requestMethod, String outputStr,String contentType) {
JSONObject jsonObject = null;
StringBuffer buffer = new StringBuffer();
try {
URL url = new URL(requestUrl);
HttpURLConnection httpUrlConn = (HttpURLConnection)url.openConnection();
httpUrlConn.setDoOutput(true);
httpUrlConn.setDoInput(true);
httpUrlConn.setUseCaches(false);
// 设置请求方式（GET/POST）
httpUrlConn.setRequestMethod(requestMethod);
//设置头信息
// httpUrlConn.setRequestProperty("Content-Type","application/x-www-form-urlencoded;charset=UTF-8");
httpUrlConn.setRequestProperty("Content-Type",contentType);
httpUrlConn.setRequestProperty("Accept","application/json;charset=UTF-8");
// 设置连接主机服务器的超时时间：15000毫秒
httpUrlConn.setConnectTimeout(15000);
// 设置读取远程返回的数据时间：60000毫秒
httpUrlConn.setReadTimeout(60000);
if ("GET".equalsIgnoreCase(requestMethod)){
httpUrlConn.connect();
}
// 当有数据需要提交时
if (null != outputStr) {
OutputStream outputStream = httpUrlConn.getOutputStream();
// 注意编码格式，防止中文乱码
outputStream.write(outputStr.getBytes("UTF-8"));
outputStream.close();
}
// 将返回的输入流转换成字符串
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
// 释放资源
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();
jsonObject = JSONObject.parseObject(buffer.toString());
} catch (ConnectException ce) {
} catch (Exception e) {
}
return jsonObject;
}
}
3）执行main方法执行即可。
