JAVA项目接入百度文心一言文本对话功能

依赖

        <dependency>
            <groupId>com.squareup.okhttp3</groupId>
            <artifactId>okhttp</artifactId>
            <version>4.0.0</version>
        </dependency>

1.获取参数

从百度云获取固定参数

        String client_id = "usl...............";
        String client_secret = "T5xrE5k...............";

3.调用代码
 

        try {
            HashMap<String, String> map = new HashMap<>();
            // 固定参数
            map.put("role", "user");
            map.put("content", "对话内容");
            jsonObject = ChatGptWenUtil.ChatGptDialogueCall(map, uid, redisOperation);
        } catch (Exception e) {
            e.printStackTrace();
        }
