我有一个react/redux应用程序，从api服务器获取一个令牌。在用户进行身份验证之后，我希望所有axios请求都具有该令牌作为授权标头，而不必手动将其附加到操作中的每个请求。我是相当新的反应/redux，我不确定最好的方法，我没有找到任何高质量的谷歌。
这是我的redux设置:
// actions.js
import axios from 'axios';
export function loginUser(props) {
const url = `https://api.mydomain.com/login/`;
const { email, password } = props;
const request = axios.post(url, { email, password });
return {
type: LOGIN_USER,
payload: request
};
}
export function fetchPages() {
/* here is where I'd like the header to be attached automatically if the user
has logged in */
const request = axios.get(PAGES_URL);
return {
type: FETCH_PAGES,
payload: request
};
}
// reducers.js
const initialState = {
isAuthenticated: false,
token: null
};
export default (state = initialState, action) => {
switch(action.type) {
case LOGIN_USER:
// here is where I believe I should be attaching the header to all axios requests.
return {
token: action.payload.data.key,
isAuthenticated: true
};
case LOGOUT_USER:
// i would remove the header from all axios requests here.
return initialState;
default:
return state;
}
}
我的令牌存储在redux store下的state.session.token。
我有点不知道该怎么做。我尝试在根目录的文件中创建一个axios实例，并更新/导入该实例，而不是从node_modules中更新/导入，但当状态发生变化时，它没有附加头文件。任何反馈/想法都非常感谢，谢谢。
对我来说，最好的解决方案是创建一个客户端服务，您将实例化您的令牌，并使用它来包装axios。
import axios from 'axios';
const client = (token = null) => {
const defaultOptions = {
headers: {
Authorization: token ? `Token ${token}` : '',
},
};
return {
get: (url, options = {}) => axios.get(url, { ...defaultOptions, ...options }),
post: (url, data, options = {}) => axios.post(url, data, { ...defaultOptions, ...options }),
put: (url, data, options = {}) => axios.put(url, data, { ...defaultOptions, ...options }),
delete: (url, options = {}) => axios.delete(url, { ...defaultOptions, ...options }),
};
};
const request = client('MY SECRET TOKEN');
request.get(PAGES_URL);
在这个客户机中，您还可以根据需要从localStorage / cookie检索令牌。
创建axios实例:
// Default config options
const defaultOptions = {
baseURL: <CHANGE-TO-URL>,
headers: {
'Content-Type': 'application/json',
},
};
// Create instance
let instance = axios.create(defaultOptions);
// Set the AUTH token for any request
instance.interceptors.request.use(function (config) {
const token = localStorage.getItem('token');
config.headers.Authorization = token ? `Bearer ${token}` : '';
return config;
});
然后，对于任何请求，将从localStorage中选择令牌，并将其添加到请求头中。
我在整个应用程序中使用相同的实例:
import axios from 'axios';
const fetchClient = () => {
const defaultOptions = {
baseURL: process.env.REACT_APP_API_PATH,
method: 'get',
headers: {
'Content-Type': 'application/json',
},
};
// Create instance
let instance = axios.create(defaultOptions);
// Set the AUTH token for any request
instance.interceptors.request.use(function (config) {
const token = localStorage.getItem('token');
config.headers.Authorization = token ? `Bearer ${token}` : '';
return config;
});
return instance;
};
export default fetchClient();
