可重用性:

创建一个文件errorHandler.js:

export const errorHandler = (error) => {
  const { request, response } = error;
  if (response) {
    const { message } = response.data;
    const status = response.status;
    return {
      message,
      status,
    };
  } else if (request) {
    //request sent but no response received
    return {
      message: "server time out",
      status: 503,
    };
  } else {
    // Something happened in setting up the request that triggered an Error
    return { message: "opps! something went wrong while setting up request" };
  }
};

然后，每当您捕捉到axios的错误时:

Just import error handler from errorHandler.js and use like this.
  try {
    //your API calls 
  } catch (error) {
    const { message: errorMessage } = errorHandlerForAction(error);
     //grab message
  }

如果你想要访问整个错误体，请按照下面所示进行:

 async function login(reqBody) {
  try {
    let res = await Axios({
      method: 'post',
      url: 'https://myApi.com/path/to/endpoint',
      data: reqBody
    });

    let data = res.data;
    return data;
  } catch (error) {
    console.log(error.response); // this is the main part. Use the response property from the error object

    return error.response;
  }

}

处理响应类型集到流的axios错误的一种方法对我有用。

.....
.....
try{
   .....
   .....
   // make request with responseType: 'stream'
   const url = "your url";
   const response = axios.get(url, { responseType: "stream" });
   // If everything OK, pipe to a file or whatever you intended to do
   // with the response stream
   .....
   .....
} catch(err){
  // Verify it's axios error
  if(axios.isAxios(err)){
    let errorString = "";
    const streamError = await new Promise((resolve, reject) => {
      err.response.data
        .on("data", (chunk) => {
           errorString += chunk;
          }
        .on("end", () => {
           resolve(errorString);
         }
      });
    // your stream error is stored at variable streamError.
    // If your string is JSON string, then parse it like this
    const jsonStreamError = JSON.parse(streamError as string);
    console.log({ jsonStreamError })
    // or do what you usually do with your error message
    .....
    .....
  }
  .....
  .....
}
   
  

如果你不想使用异步等待尝试

export const post = async ( link,data ) => {
const option = {
    method: 'post',
    url: `${URL}${link}`,
    validateStatus: function (status) {
        return status >= 200 && status < 300; // default
      },
    data
};

try {
    const response = await axios(option);
} catch (error) {
    const { response } = error;
    const { request, ...errorObject } = response; // take everything but 'request'
    console.log(errorObject);
}

我尝试使用try{}catch{}方法，但它不适合我。然而，当我切换到使用.then(…).catch(…)时，AxiosError被正确捕获，我可以随意使用。当我在设置断点时尝试前者时，它不允许我看到AxiosError，而是告诉我捕获的错误是未定义的，这也是最终在UI中显示的错误。

不知道为什么会这样，我觉得这很微不足道。出于这种原因，我建议使用上面提到的传统的.then(…).catch(…)方法来避免向用户抛出未定义的错误。

    let res = await axios.get('/my-api-route');

    // Work with the response...
} catch (err) {
    if (err.response) {
        // The client was given an error response (5xx, 4xx)
    } else if (err.request) {
        // The client never received a response, and the request was never left
    } else {
        // Anything else
    }
}

try {
    let res = await axios.get('/my-api-route');

    // Work with the response...
} catch (err) {
    if (err.response) {
        // The client was given an error response (5xx, 4xx)
    } else if (err.request) {
        // The client never received a response, and the request was never left
        console.log(err.request);
    } else {
        // Anything else
    }
}
