使API通过Async/Await提取"POST"的正确方法 [英] Proper Way to Make API Fetch 'POST' with Async/Await

问题描述

我正在研究一个需要我向API发出请求的项目.用Async/Await发出POST请求的正确形式是什么?

I'm working on a project that requires me to make requests to an API. What is the proper form for making a POST request with Async/Await?

作为一个例子，这是我获取所有设备列表的信息.我将如何将此请求更改为POST以创建新设备?我知道我必须添加带有数据正文的标头.

As an example, here is my fetch to get a list of all devices. How would I go about changing this request to POST to create a new device? I understand I would have to add a header with a data body.

getDevices = async () => {
  const location = window.location.hostname;
  const response = await fetch(
    `http://${location}:9000/api/sensors/`
  );
  const data = await response.json();
  if (response.status !== 200) throw Error(data.message);
  return data;
};

推荐答案

实际上，您的代码可以像这样进行改进:

actually your code can be improved like this:

要做一个帖子，只需在fetch调用的设置上添加方法.

to do a post just add the method on the settings of the fetch call.

getDevices = async () => {
    const location = window.location.hostname;
    const settings = {
        method: 'POST',
        headers: {
            Accept: 'application/json',
            'Content-Type': 'application/json',
        }
    };
    try {
        const fetchResponse = await fetch(`http://${location}:9000/api/sensors/`, settings);
        const data = await fetchResponse.json();
        return data;
    } catch (e) {
        return e;
    }    

}
