我尝试的第一个方法是：

static async callSendApi(requestBody) {
    let url = new URL(

        `${API_URL}/${PAGE_ID}/messages`

    );
    url.search = new URLSearchParams({
      access_token: `${PAGE_ACCESS_TOKEN}`,
    });
    console.warn("Request body is\n" + JSON.stringify(requestBody));
    let response = await axios.post(url, {
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify(requestBody),
      // access_token: `${PAGE_ACCESS_TOKEN}`,
    });
    if (!response.ok) {
      consoleconst`Unable to call Send API: ${response.statusText}`,
        await response.json();
    }
  }

我尝试的第二种方法是：

static async callSendApi(requestBody) {
    let url = new URL(
      `${API_URL}/${PAGE_ID}/messages?access_token=${PAGE_ACCESS_TOKEN}`
    );
    /* url.search = new URLSearchParams({
      access_token: `${PAGE_ACCESS_TOKEN}`,
    });*/
    console.warn("Request body is\n" + JSON.stringify(requestBody));
    let response = await axios.post(url, {
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify(requestBody),
      // access_token: `${PAGE_ACCESS_TOKEN}`,
    });
    if (!response.ok) {
      consoleconst`Unable to call Send API: ${response.statusText}`,
        await response.json();
    }
  }

我得到错误是：

error: { 
    message: 'Unknown path components: /messagesaccess_token=access_token
    type: 'OAuthException',
    code: 2500,
    fbtrace_id: 'AbBJGVotjz3ijKKLzVE6_CM'
    }

我在两种情况下都收到了这个错误。两种情况下都跳过了'？'标记。我不知道发生了什么。我使用heroku来处理这个问题。我尝试删除并重新部署存储库来确认代码是否没有更新。但仍然出现了这个错误。：（。
