axios请求失败 如何获取后端接口返回的状态码及错误信息
这两天在写前端项目时候遇到个问题,后端异常做了统一处理,错误信息和提示都在返回的json中,在做校验或其他非正常情况下,返回错误的状态码,则axios直接报错,无法拿到后端返回的json。但是我需要向用户展示后端返回的json中的错误信息,用普通的catch方法只能获取到浏览器返回的400等错误提示,不能获取到后端返回的json,后经查阅得出下面方法:
axios.get('api/user/1')
.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);
});
