一种常见的方法是在.catch()方法中通过error.response来获取响应对象,然后再从响应对象中获取数据。 axios.get('.then(response=>{console.log(response.data);}).catch(error=>{if(error.response){console.log(error.response.data);}}); 1. 2. 3. 4. 5. 6. 7. 8. 9. 在上面的代码中,我们通过判...

.catch(error) 异常中的字段: error.response 当axios 获得的响应 status code 超出了 2xx 的范围时, axios 将会抛出异常. 实际获取到的响应数据会被赋值给 异常对象的 response 字段 error.request 当axios 请求得不到响应的时候, 异常中会有 request 字段. 错误处理 通过在 .catch(error) 的回调...
Describe the bug When using a response reject interceptor, the AxiosError object does not contain the original message in case of 503 Server Unavailable HTTP status code. To Reproduce Code snippet to reproduce, ideally that will work by ...
### Summary Hello, I am making an API HTTP request using axios but i don't get an error object in response. The response for the error comes as undefined and I only get the instance of an error object if I console.log(error). I have fol...
console.log(error.response.headers); } else { // 请求未发送或者发生了网络错误 console.log(error.message); } }); 在上述示例中,首先判断error对象是否有response属性,如果有则输出响应信息,如果没有则输出错误信息。这样可以避免在error.response未定义的情况下导致代码报错。
