Api 将提取post请求转换为axios post请求

我正在尝试将以下

fetch

请求转换为

axios

，但失败

export const createPost = postData => dispatch => {
  fetch('https://jsonplaceholder.typicode.com/posts', {
    method: 'POST',
    headers: {
      'content-type': 'application/json'
    },
    body: JSON.stringify(postData)
  })
    .then(res => res.json())
    .then(post =>
      dispatch({
        type: NEW_POST,
        payload: post,
      })
    );
};

我就是这样做的

export const createPost = postData => dispatch => {
  axios({
    method: "post",
    url: "https://jsonplaceholder.typicode.com/posts",
    headers: {
      'content-type': 'application/json',
    },
    body: JSON.stringify(postData),
  })
    .then((res) => dispatch({
        type: NEW_POST,
        payload: res,
      }))
    .catch((err) => console.log(err));
}

这就是调用上述函数的方式

const post = {
  title: this.state.title,
  body: this.state.body
};

this.props.createPost(post);

你能帮我做这个吗
