React Native应用程序不会获取api数据 [英] React Native app won't fetch api data

问题描述

我的React Native应用程序不会获取或获取api数据.它不会控制台日志数据，甚至不会出错.我已经尝试过使用fetch和axios.

My React Native app won't fetch or get api data. It will not console log data or even an error. I've tried using fetch and axios.

获取方法:

    export default class List extends React.Component {
      commponentDidMount() {
        fetch(URL)
        .then((response) => response.json())
        .then((responseData) => {
          console.log(responseData);
        })
        .catch(error => {
            console.log(error);
        });
      }
    }

axios方法:

    export default class List extends React.Component {
      commponentDidMount() {
        axios.get(URL)
        .then(function (response) {
          console.log(response);
        })
        .catch(function (error) {
          console.log(error);
        });
      } 
    }

我不确定是什么问题，也无法在线找到解决方案.

I'm not sure what the problem is and I can't find a solution online.

推荐答案

请检查拼写功能 componentDidMount 并尝试下面的示例代码.

Please do check spelling function componentDidMount And try below sample code I have.

componentDidMount() {
  let URL = `https://...`;

  fetch(URL)
  .then(res => res.json())
  .then(res => {
      console.log('response:', res.data);
  });
}

希望这会有所帮助.
