你可以在 `payload` 中加入一个键值对 `stream`，如果复选框被勾选，则值为 True，否则为 False。然后在发送请求时，只有当 `stream` 的值为 True 时才把 `cid` 回传到服务器。

修改后的代码可以如下所示：

def on_submit(self):
    prompt = self.prompt_edit.toPlainText()
    question = self.question_edit.toPlainText()
    api_url = "https://api.devbit.cn/ai/api/ai/chat"
    api_key = "ZXlKMGVYQWlPaUpLVjFRaUxDSmhiR2NpT2lKSVV6STFOaUo5LmV5SjBkQ0k2TkN3aVlYVmtJam9pTlRNeE5XTmpZekV3TlRnME5HSTNNVGcyWmpoa09XRTVOVFppTnpGbU5HWWlMQ0pzZFNJNkltZGhiMmhoYjNkbGJpSXNJbVY0Y0NJNk1UWTROVFUwT0RjNU9Td2lkWElpT2pJc0ltcDBhU0k2SWtGUVNWOVVUMHRGVGw4MU16RTFZMk5qTVRBMU9EUTBZamN4T0RabU9HUTVZVGsxTm1JM01XWTBaaTAwSW4wLjM0WWhudzVpblNRVTZROWpkZ0RxRHlCQk1GM2xmN01HYTZBcXZJMV9ydjA="
    headers = {
        "Authorization": "Bearer "+api_key,
        "Accept": "application/json"
    }
    stream = self.checkbox.isChecked()
    payload = {
        "prompt": prompt,
        "question": question,
        "stream": stream
    }
    if stream:
        payload["cid"] = self.cid

    response = requests.post(api_url, json=payload, headers=headers)

    if response.status_code == 200:
        print(response.json())
        json_response = response.json()
        if stream:
            self.cid = str(json_response['data']['cid'])
        self.json_response_edit.setText(str(json_response['data']['answer']))
    else:
        print("Request failed with error code {reaponse.status_code}")
        self.json_response_edit.setText(f"请求失败，错误码 {response.status_code}")

这样，如果复选框被勾选，`cid` 才会被回传。
