登录之后，页面没有自动跳转， 需要手动刷新一下

1. 登录成功之后，页面没有跳转，需要手动刷新一下，才到目标页面。代码如下：

<template>
<view class="login">
<uni-card :is-shadow="false" :border="false">
<view class="login-title">
登录
</view>
<uni-forms ref="loginForm" :modelValue="login" label-position="left">
<uni-forms-item label="账号" required>
<uni-easyinput v-model="login.username" placeholder="账号" />
</uni-forms-item>
<uni-forms-item label="密码" required>
<uni-easyinput type="password" v-model="login.password" placeholder="密码" />
</uni-forms-item>
<uni-forms-item label="验证码" required>
<uni-easyinput v-model="login.captcha" placeholder="验证码" />
</uni-forms-item>
<uni-forms-item label=" ">
<image :src="captchaUrl" style="height: 40px;width: 150px;" @click="getCaptchaUrl"></image>
</uni-forms-item>
</uni-forms>
<view>
<button type="primary" @click="loginSubmit">登录</button>
</view>
</uni-card>
</view>
</template>

<script>
import {getUuid} from '@/utils/index';
import {useLoginApi} from '@/api/login';

export default {
data() {
return {
login:{
username: '',
password: '',
captcha: '',
uuid: ''
},
captchaUrl: ''
}
},
onLoad() {
if (this.$store.state.user.token){
uni.reLaunch({
url: '/pages/index/post'
});
}else {
this.getCaptchaUrl();
}
},
methods: {
getCaptchaUrl() {
this.login.uuid = getUuid();
this.captchaUrl = ${uni.$u.http.config.baseURL}/captcha?uuid=${this.login.uuid};
},
loginSubmit() {
useLoginApi(this.login).then(res =>{
this.$store.commit('user/setToken', res.data.token)

            uni.navigateTo({  
                url: '/pages/indes/post'  
            });  
            setTimeout(() => {  
                        console.log('after reLaunch');  
                    }, 1000);   
        }).catch(e =>{  
            this.getCaptchaUrl();  
        })  
    }  
}  

}
</script>
