axios 响应拦截获取返回状态码方式整理
方法一
js
axios.interceptors.response.use(
response => {
console.log('拦截器响应成功')
return response
},
error => {
console.log('拦截器响应失败')
console.log(error)
if(error.request){
console.log(error.request)
} else if(error.response){
console.log(error.response.data);
console.log(error.response.status);
}
if (error && error.response) {
switch (error.response.status) {
case 400: error.message = '请求错误(400)';
break;
case 401: error.message = '未授权，请重新登录(401)';
break;
case 403: error.message = '拒绝访问(403)';
break;
case 404: error.message = '请求出错(404)';
break;
case 408: error.message = '请求超时(408)';
break;
case 500: error.message = '服务器错误(500)';
break;
case 501: error.message = '服务未实现(501)';
break;
case 502: error.message = '网络错误(502)';
break;
case 503: error.message = '服务不可用(503)';
break;
case 504: error.message = '网络超时(504)';
break;
case 505: error.message = 'HTTP版本不受支持(505)';
break;
default: error.message = '连接出错'(${error.response.status})!;
}
}else{
error.message ='连接服务器失败!'
}
return Promise.reject(error)
}
)
方法二
js
// request请求拦截器
axios.interceptors.request.use(
config => {
Indicator.open({
text: '加载中...',
spinnerType: 'fading-circle'
});
//如果cookie中存在Authorization
if(sessionStorage.getItem('Authorization')){
config.headers.common['Authorization'] = sessionStorage.getItem('Authorization')
config.headers.common['loginAuth'] = sessionStorage.getItem('loginAuth')
}
return config
},
error => {
Promise.reject(error)
}
);
//response响应拦截器
axios.interceptors.response.use(
response => {
if(sessionStorage.getItem('Authorization')){
// 返回code === 1 || 返回code === 2
if(response.data.code === 1){
MessageBox.alert(response.data.msg).then(action=>{})
}else if(response.data.code === 2){
MessageBox.alert(response.data.msg).then(action=>{
sessionStorage.removeItem('Authorization')
router.push('/login')
})
}
}
Indicator.close() //响应成功，关闭全局的Indicator
return response
},
error => {
Indicator.close() // 响应错误，关闭全局的Indicator
if(error){
const {response} = error
if(response.status >= 400 && response.status < 500){ MessageBox.alert('资源不存在，请稍后重试').then(action=>{
})
}else if(response.status >= 500){
MessageBox.alert('服务异常，请稍后重试').then(action=>{
})
}
if(response.data.message === 'Network Error'){
MessageBox.alert('网络异常，请稍后重试').then(action=>{
})
}
}
return Promise.reject(error)
}
);
方法三
js
// axios请求拦截器
// 每次发送axios请求，都要带上一个token
axios.defaults.timeout = 120000 // 设置默认timeout为2分钟
axios.interceptors.request.use(
config => {
config.headers['Content-Type'] = 'application/json; charset=UTF-8'
config.headers['Cache-Control'] = 'no-catch'
const token = window.localStorage.getItem('accesstoken')
if (token) {
config.headers.common['access-token'] = `${token}`
}
return config
},
err => {
console.log(err)
return Promise.reject(err)
}
)
axios.interceptors.response.use(
response => {
const tokentimer = Number(window.localStorage.getItem('tokentimer'))
const tokenTimerStamp = Number(response.headers['token-timestamp'])
/* 时间戳比之前时间戳大的时候替换token */
if (tokentimer < tokenTimerStamp) { window.localStorage.setItem('accesstoken', response.headers['access-token']) window.localStorage.setItem('tokentimer', response.headers['token-timestamp']) } if (response.status === 200) { // 导出成功不返回下面的字段 let _isTrue = response.data.success // 返回成功 let _message = response.data.message // 返回提示信息 let codeNum = response.data.code let _code, _code3 if (codeNum) { _code = codeNum.toString().slice(0, 1) // 返回失败 _code3 = codeNum.toString().slice(0, 4) } else { // 排除导出时成功没有返回code 导致报错 if (response.data.code) { Vue.prototype.$message({ message: `${codeNum}请求异常，请联系管理员！`, type: 'error' }) } } if (_isTrue && codeNum === 20000) { // 返回成功请求 } else { if (_code === '2' && codeNum !== 20000) { Vue.prototype.$message({ message: `${codeNum}:${_message}`, type: 'error' }) } else if (_code === '5' || _code === '6') { // 状态码为5，6开头的为服务器错误 Vue.prototype.$message({ dangerouslyUseHTMLString: true, message: `${codeNum}:${_message}`, type: 'error' }) } else if (_code === '4') { // 状态码为4开头的为权限问题，无法登录 if (_code3 === '4032') { router.push('/login') } else { Vue.prototype.$message({ message: `${codeNum}:${_message}`, type: 'error' }) } } } return Promise.resolve(response) } return Promise.reject(response) }, error => {
if (error.response) {
Vue.prototype.$message({
message: '系统异常，请联系管理员！',
type: 'error'
})
} else {
Vue.prototype.$message({
message: '网络不给力',
type: 'error'
})
}
return Promise.reject(error) // 返回接口返回的错误信息
})
