在 Axios 文档中:
但在浏览器中,我们可以知道状态码:
在提出这个问题之前,我已经阅读了如何从Axios的http错误中获取状态码?这篇文章。但是这篇文章似乎与我的不同。
axios.get('/user/12345')
.catch(function (error) {
if (error.response) {
// The request was made and the server responded with a status code
// that falls out of the range of 2xx
console.log(error.response.data);
console.log(error.response.status);
console.log(error.response.headers);
} else if (error.request) {
// The request was made but no response was received
// `error.request` is an instance of XMLHttpRequest in the browser and an instance of
// http.ClientRequest in node.js
console.log(error.request);
} else {
// Something happened in setting up the request that triggered an Error
console.log('Error', error.message);
}
console.log(error.config);
});
我们知道可以在 .catch()
方法中捕获错误。
但是当我使用Django-Rest-Framework作为后端API提供程序时,它只提供数据,没有状态:
你看到了这个错误:error
。{username: ["A user with that username already exists."]}
