本想等項目作完再連載一波系列博客,隨着開發的進行,也是的確遇到了很多坑,請教了很多人。遂想,何不一邊記錄踩坑,一邊分享收穫呢。分享固然是好的, 若是能作到集思廣益,那豈不是更美。咱們的口號是:堅定不會爛尾前端
本博客爲連載代碼博客同步更新博客,隨着項目日後開發可能會遇到前面寫的不合適的地方會再回頭修改。若有不妥~歡迎兄弟們不嗇賜教。謝謝!react
class Home extends Component {
constructor(props) {
super(props);
this.shouldComponentUpdate = PureRenderMixin.shouldComponentUpdate.bind(this)
}
render() {
const {login,register} = this.props;
localStorage.setItem('userInfo',JSON.stringify(this.props.userInfo));
return (
this.props.match.params.tag && (tags.indexOf(this.props.match.params.tag) === -1 || this.props.location.pathname.lastIndexOf('\/') > 0)
?

由於未來咱們會以標籤來做爲路由,展現不一樣標籤頁下的文章列表,因此當沒有匹配到url沒有匹配到對應標籤的時候,咱們顯示404頁面。git
首頁部分主要包括如下幾項。輪播圖(這裏僅僅用做UI美觀吧),標籤,文章列表,分頁,登陸功能。github
因此對於複雜編碼的部分,咱們單獨抽出組件。而對於Home.js這個文件,也是點擊全部標籤對應的公共頁面。只是文章列表不一樣而已。express
別的組件都是常規編碼,這裏說下form組件吧redux
class LoginFormCom extends Component {
constructor(props) {
super(props);
}
handleLogin = (e) => {
e.preventDefault();
this.props.form.validateFields((err, values) => {
if (!err) {
this.props.login(values.userName,values.password)
}
});
};
render() {
const {getFieldDecorator} = this.props.form;
return (
<Form onSubmit={this.handleLogin} className={style.formStyle}>
<FormItem>
{getFieldDecorator('userName', {
rules: [{required: true, message: '請輸入用戶名!'}],
})(
<Input prefix={<Icon type="user" style={{fontSize: 13}}/>} placeholder="Username"/>
)}
</FormItem>
<FormItem>
{getFieldDecorator('password', {
rules: [{required: true, message: '請輸入密碼!'}],
})(
<Input prefix={<Icon type="lock" style={{fontSize: 13}}/>} type="password"
placeholder="Password"/>
)}
</FormItem>
<FormItem>
<Button className={style.loginButton} type="primary" htmlType="submit">
登陸
</Button>
</FormItem>
</Form>
)
}
}
const LoginForm = Form.create()(LoginFormCom);
export default LoginForm

這裏我是將登陸和註冊單獨拿出來寫了兩個組件的。具體寫法能夠參考antd官方文檔。後端
這部分說的saga僅僅是一些全局信息的saga,包含錯誤信息提醒、全局的Loading、登陸狀態等。並不是首頁文章列表標籤的saga微信
const initialState = {
isFetching: true,
msg: {
type: 1,//0失敗 1成功
content: ''
},
userInfo: {}
};
export const actionsTypes = {
FETCH_START: "FETCH_START",
FETCH_END: "FETCH_END",
USER_LOGIN: "USER_LOGIN",
USER_REGISTER: "USER_REGISTER",
RESPONSE_USER_INFO: "RESPONSE_USER_INFO",
SET_MESSAGE: "SET_MESSAGE",
USER_AUTH:"USER_AUTH"
};
export const actions = {
get_login: function (username, password) {
return {
type: actionsTypes.USER_LOGIN,
username,
password
}
},
get_register: function (data) {
return {
type: actionsTypes.USER_REGISTER,
data
}
},
clear_msg: function () {
return {
type: actionsTypes.SET_MESSAGE,
msgType: 1,
msgContent: ''
}
},
user_auth:function () {
return{
type:actionsTypes.USER_AUTH
}
}
};
export function reducer(state = initialState, action) {
switch (action.type) {
case actionsTypes.FETCH_START:
return {
...state, isFetching: true
};
case actionsTypes.FETCH_END:
return {
...state, isFetching: false
};
case actionsTypes.SET_MESSAGE:
return {
...state,
isFetching: false,
msg: {
type: action.msgType,
content: action.msgContent
}
};
case actionsTypes.RESPONSE_USER_INFO:
return {
...state, userInfo: action.data
};
default:
return state
}
}
// const front = combineReducers({
// // home
// });
export default combineReducers({
// front,
globalState: reducer,
admin
})

說下幾個狀態。session
FETCH_START: "開始進行異步請求",
FETCH_END: "異步請求結束",
USER_LOGIN: "用戶登陸",
USER_REGISTER: "用戶註冊",
RESPONSE_USER_INFO: "收到登陸信息",
SET_MESSAGE: "設置全局提醒",
USER_AUTH:"USER_AUTH"//後面免登錄再說這個

對應中saga的處理
export function* login(username, password) {
yield put({type: IndexActionTypes.FETCH_START});
try {
return yield call(post, '/user/login', {username, password})
} catch (error) {
yield put({type:IndexActionTypes.SET_MESSAGE,msgContent:'用戶名或密碼錯誤',msgType:0});
} finally {
yield put({type: IndexActionTypes.FETCH_END});
}
}
export function* register (data) {
yield put({type:IndexActionTypes.FETCH_START});
try {
return yield call(post, '/user/register', data)
} catch (error) {
yield put({type:IndexActionTypes.SET_MESSAGE,msgContent:'註冊失敗',msgType:0});
} finally {
yield put({type: IndexActionTypes.FETCH_END});
}
}
export function* loginFlow() {
while (true) {
let request = yield take(IndexActionTypes.USER_LOGIN);
let response = yield call(login, request.username, request.password);
if(response&&response.code === 0){
yield put({type:IndexActionTypes.SET_MESSAGE,msgContent:'登陸成功!',msgType:1});
yield put({type:IndexActionTypes.RESPONSE_USER_INFO,data:response.data})
}
}
}
export function* registerFlow () {
while(true){
let request = yield take(IndexActionTypes.USER_REGISTER);
let response = yield call(register, request.data);
if(response&&response.code === 0){
yield put({type:IndexActionTypes.SET_MESSAGE,msgContent:'註冊成功!',msgType:1});
yield put({type:IndexActionTypes.RESPONSE_USER_INFO,data:response.data})
}
}
}
export function* user_auth () {
while(true){
yield take(IndexActionTypes.USER_AUTH);
try {
yield put({type:IndexActionTypes.FETCH_START});
let response = yield call(get,'/user/userInfo');
if(response && response.code === 0){
yield put({type:IndexActionTypes.RESPONSE_USER_INFO,data:response.data})
}
}catch (err){
console.log(err);
}finally {
yield put({type: IndexActionTypes.FETCH_END});
}
}
}

saga中主要是對用戶登陸和註冊的處理。每個saga處理函數中都須要put一個請求開始和請求結束的action,若是請求錯誤,則須要設置全局狀態提醒。
user_auth是後面免登錄的一個saga處理,後續介紹,這裏你們能夠略過。
如上,在登陸的時候,咱們dispatch一個login的action,saga則會捕捉該action,而後對應處理後,put相應的action給reducer。
具體的操做,你們能夠自行github上查看代碼
該部分主要是前端操做,因此代碼部分都是在 /app 文件夾下。
