            if (responseCode != HttpURLConnection.HTTP_OK) {
                throw new IOException("HTTP error code: " + responseCode);
            }

            // 处理text/event-stream响应
            InputStream inputStream = connection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(inputStream, StandardCharsets.UTF_8));

            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line).append("\n");
                // 如果是SSE流式响应，可以在这里实时处理每一行数据
                System.out.println("Received SSE event: " + line);
            }

        } finally {
            if (reader != null) {
                reader.close();
            }
            if (connection != null) {
                connection.disconnect();
            }
        }

        return response.toString();
    }
}

这个Java代码实现了：

使用HttpURLConnection创建POST请求
设置了所有必要的请求头
发送了JSON格式的请求体
处理text/event-stream类型的响应，逐行读取服务器推送的数据

注意事项：

由于这是一个SSE(Server-Sent Events)流式响应，实际应用中可能需要更复杂的处理逻辑来解析事件流格式
代码中包含了实时打印接收到的每一行数据的逻辑，你可以根据需要修改这部分
如果需要处理更复杂的SSE事件（如不同的事件类型、重连机制等），可能需要实现更完整的SSE客户端
某些头部信息可能包含敏感数据，实际应用中应考虑安全性问题

如果你需要更高级的SSE处理功能，可以考虑使用专门的SSE客户端库，如OkHttp的EventSource或其他Java SSE客户端实现。

我试试

好的！你试试看。这个代码应该可以正常工作，但处理SSE流式响应时可能需要根据实际返回的数据格式做一些调整。

如果你在测试过程中遇到任何问题，比如：

连接问题
响应格式解析问题
编码问题
或者需要修改为更实时的流式处理

随时告诉我，我可以帮你调整代码。特别是SSE流式响应，可能需要根据腾讯源宝API的实际返回格式来优化处理逻辑。

测试时注意观察控制台输出的每一行数据，这样可以了解API返回的具体格式。

祝你测试顺利！🚀

以下是将给定的JSON字符串转换为FastJSON的JSONObject对象，然后再转换回字符串的代码实现：

JAVA

import com.alibaba.fastjson.JSONObject;

public class JsonExample {
    public static void main(String[] args) {
        // 创建最外层的JSONObject
        JSONObject requestBodyJson = new JSONObject();
        
        // 添加顶层属性
        requestBodyJson.put("model", "gpt_175B_0404");
        requestBodyJson.put("prompt", "你好呀");
        requestBodyJson.put("plugin", "Adaptive");
        requestBodyJson.put("displayPrompt", "你好");
        requestBodyJson.put("displayPromptType", 1);
        
        // 创建options对象
        JSONObject options = new JSONObject();
        JSONObject imageIntention = new JSONObject();
        imageIntention.put("needIntentionModel", true);
        imageIntention.put("backendUpdateFlag", 2);
        imageIntention.put("intentionStatus", true);
        options.put("imageIntention", imageIntention);
        requestBodyJson.put("options", options);
        
        // 添加其他属性
        requestBodyJson.put("multimedia", new JSONObject().newJSONArray()); // 空数组
        requestBodyJson.put("agentId", "naQivTmsDa");
        requestBodyJson.put("supportHint", 1);
        requestBodyJson.put("extReportParams", null);
        requestBodyJson.put("isAtomInput", false);
        requestBodyJson.put("version", "v2");
        requestBodyJson.put("chatModelId", "deep_seek_v3");
        
        // 注意：chatModelExtInfo 是一个字符串形式的JSON
        String chatModelExtInfoStr = "{\"modelId\":\"deep_seek_v3\",\"subModelId\":\"\",\"supportFunctions\":{\"internetSearch\":\"closeInternetSearch\"}}";
        requestBodyJson.put("chatModelExtInfo", chatModelExtInfoStr);
        
        requestBodyJson.put("applicationIdList", new JSONObject().newJSONArray()); // 空数组
        
        // 创建supportFunctions数组
        JSONObject supportFunctionsArray = new JSONObject().newJSONArray();
        supportFunctionsArray.add("closeInternetSearch");
        requestBodyJson.put("supportFunctions", supportFunctionsArray);
        
        // 将JSONObject转换为字符串
        String jsonString = requestBodyJson.toJSONString();
        
        System.out.println("Generated JSON:");
        System.out.println(jsonString);
    }
}

这段代码会生成与原始JSON字符串等效的JSON对象，并输出如下结果：

JSON

{
    "model":"gpt_175B_0404",
    "prompt":"你好呀",
    "plugin":"Adaptive",
    "displayPrompt":"你好",
    "displayPromptType":1,
    "options":{
        "imageIntention":{
            "needIntentionModel":true,
            "backendUpdateFlag":2,
            "intentionStatus":true
        }
    },
    "multimedia":[],
    "agentId":"naQivTmsDa",
    "supportHint":1,
    "extReportParams":null,
    "isAtomInput":false,
    "version":"v2",
    "chatModelId":"deep_seek_v3",
    "chatModelExtInfo":"{\"modelId\":\"deep_seek_v3\",\"subModelId\":\"\",\"supportFunctions\":{\"internetSearch\":\"closeInternetSearch\"}}",
    "applicationIdList":[],
    "supportFunctions":["closeInternetSearch"]
}

关键点说明：

使用JSONObject创建嵌套的JSON结构
chatModelExtInfo字段保持为字符串形式（因为它本身就是JSON字符串）
空数组使用newJSONArray()方法创建
使用toJSONString()方法将JSON对象转换为字符串
保持了原始JSON的所有结构和值

这种方法比直接使用字符串更灵活，因为：

可以动态修改字段值
避免手动处理转义字符
更容易维护复杂的JSON结构
减少因格式错误导致的bug
