一、文件路径截图
2、新建一个文件app.js
let host='http://172.16.192.40:8083/jeecg-boot/' //本地接口
let myApi = {
login: `${host}wx/wxUser/login`, //登录
}
module.exports = myApi3、新建一个文件request.js
import myApi from '@/utils/app.js';
export const request = (options) => {
console.log(options, `调用接口`)
return new Promise((resolve, reject) => {
const WXUSER = uni.getStorageSync('WXUSER');
if (!options.url) return console.error('请传入URL')
else sendRequest(options, resolve, reject);
})
};
//封装的发送请求函数
function sendRequest(options, resolve, reject) {
const WXUSER = uni.getStorageSync('WXUSER');
uni.request({
url: options.url,
data: options.data || '',
method: options.method || 'POST',
header: {
"X-Access-Token": WXUSER.rememberToken, //传递的token
},
success: (res) => {
if (res.data.code == 401) {
console.log('返回401,token失效')
wxlogin(options).then(() => {
sendRequest(options, resolve, reject);
});
} else resolve(res.data)
}
})
}
//封装的登录 登陆成功后获取信息
export async function wxlogin(options) {
return new Promise((resolve, reject) => {
uni.getUserInfo({
success: (UserRes) => {
uni.login({
desc: 'weixin',
success: res => {
wx.request({
url: myApi.login,
method: 'POST',
data: {
weappCode: res.code,
},
success: res => {
if (res.data.success) {
console.log(res.data.result.wxUser)
const WXUSER = res.data.result.wxUser
const SYSUSER = res.data.result.sysUser
uni.setStorageSync('WXUSER',WXUSER);
uni.setStorageSync('SYSUSER',SYSUSER);
resolve(); // 登录成功后，返回resolve
} else {
console.log('登录错误', res)
reject(); // 登录失败时，返回reject
}
}
});
}
});
}
})
});
}4、页面使用
<!-- 首页 -->
<template>
</template>
<script>
import myApi from '@/utils/app.js' //调用接口使用
export default {
components: {
},
data() {
return {
dataSource: [],
};
},
onLoad() {
this.loadData()
},
methods: {
async loadData() {
try {
const res = await this.$request({
url: myApi.CcrUgcList,
method: 'GET',
});
console.log(res)
if (res.code === 200) {
this.dataSource = res.result.records
}
} catch (e) {
// 失败执行
console.log(`这个接口错误：${myApi.CcrUgcList}`)
} finally {
// 执行代码正确、报错都执行
}
},
}
};
</script>
<style lang="scss" scoped>
</style>
