在 create-react-app 中使用 Netlify 函数时出现 304 错误

Question

※发布问题后编辑了一些代码。新代码如下。

我正在尝试使用 Netlify 函数来隐藏我的 API 密钥以获取数据。但是，它返回 304 并且似乎无法正常工作。 以下代码返回错误“SyntaxError: Unexpected token

谁能帮我解决这个问题？

■functions/fetch-weather.js

const handler = async (event) => {
  try {
    const { city } = event.queryStringParameters;
    const API = process.env.REACT_APP_API_KEY;

    const response = await fetch(
      `https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=${API}`
    );

    const data = await response.json();
    
    return {
      statusCode: 200,
      body: JSON.stringify(data),
    };
  } catch (error) {
    console.log({ statusCode: 500, body: error.toString() });
    return { statusCode: 500, body: error.toString() };
  }
};

module.exports = { handler };

■getCurrentWeather.js

export const getCurrentWeather = async (
  city,
  setLocation,
  setWeather,
  setNotification
) => {
  const fetchWeather = async () => {
    setNotification({ status: 'pending', message: 'Loading...' });

    const response = await fetch(
      `/.netlify/functions/fetch-weather?city=${city}`
    );

    if (!response.ok) {
      throw new Error('cannot get current weather data');
    }

    const data = await response.json();
    return data;
  };

  try {
    const data = await fetchWeather();
    console.log(data);
    setLocation(data.name);
    const [array] = data.weather;
    setWeather(array.main, array.description);
    setNotification({ status: 'success', message: 'Success' });
  } catch (error) {
    console.log(error);
    setNotification({ status: 'error', message: 'Cannot find result' });
  }
};

■netlify.toml

[build]
    functions = "functions"
    publish = "src"

■package.json （运行“npm i netlify-cli --save-dev”）

"devDependencies": {
    "netlify-cli": "^6.8.12"
  }

■控制台图像（使用“netlify dev”打开页面后） error network

在您的 netlify 函数发出请求后，您需要使用 .json 来获取 json 数据

const response = await fetch(
      `https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=${API}`
    );

const data = await response.json();
