我遇到登录后商店数据“菜单”未更新的问题。 出乎意料..在我调用“getMenus”之前,对象“loggedInUser”没有坐过。我不确定我在这里做错了什么......
PS!在chrome中调试时,我注意到在输入api调用时loggedInUser为“null”(请参阅api.js codesnippet)。
Login.vue(方法):
methods: {
doLogin() {
this.errorMessage = '';
this.loading = true;
let userCredentials = {
'username': this.loginEmail,
'password': this.loginPassword
};
this.$store.dispatch('tryLogin', {
'login': this.loginEmail,
'password': this.loginPassword
}).then((response) => {
this.$store.dispatch('getMenus')
.then((response) => {
this.$router.push('/')
});
});
}
},
Menus.vue(与/相同)
computed: {
menus() {
return this.$store.getters.menus
}
},
created() {
this.$store.dispatch('getMenus')
},
methods: {
viewMenu: function(item) {
console.log("=> View Menu : " + item.Name)
this.$router.push('/viewmenu/' + item.Id)
}
}
}
store.js(getMenus action AND tryLogin)
actions: {
getMenus({ commit, getters }) {
api.getMenus(getters.loggedInUser)
.then(menus => {
commit('UPDATE_MENUS', menus);
});
},
tryLogin({ commit }, credentials) {
api.tryLogin(credentials)
.then(loggedInUser => {
commit('LOGGED_IN_USER', loggedInUser);
});
},
api.js(getMenus功能)
getMenus(loggedInUser) {
var hostname = 'http://myurl'
var config = {
headers: {
'Content-Type': 'application/json'
}
}
var endpointUrl = hostname + '/api/Menu/GetMenus';
if (loggedInUser != null){
endpointUrl = hostname + '/api/Menu/GetMenusForSubCompany/' + loggedInUser.encryptedsubcompanyid;
}
return axios.get(endpointUrl, config)
.then(response => response.data);
},

从您的store.js
代码段中,您似乎忘了回复承诺。
