uni-app 请求封装

1.创建一个http.js 

​
const baseUrl = 'http://192.168.1.188:8080'; 
const httpRequest = (opts, data) => {
let httpDefaultOpts = {
url: baseUrl+opts.url,
data: data,
method: opts.method,
header: opts.method == 'get' ? {
'X-Requested-With': 'XMLHttpRequest',
"Accept": "application/json",
"Content-Type": "application/json; charset=UTF-8"
} : {
'X-Requested-With': 'XMLHttpRequest',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
dataType: 'json',
}
let promise = new Promise(function(resolve, reject) {
uni.request(httpDefaultOpts).then(
(res) => {
resolve(res[1])
}
).catch(
(response) => {
reject(response)
}
)
})
return promise
};
//带Token请求
const httpTokenRequest = (opts, data) => {
let token = "";
uni.getStorage({
key: 'token',
success: function(ress) {
token = ress.data
}
});
//此token是登录成功后后台返回保存在storage中的
let httpDefaultOpts = {
url: baseUrl+opts.url,
data: data,
method: opts.method,
header: opts.method == 'get' ? {
'Token': token,
'X-Requested-With': 'XMLHttpRequest',
"Accept": "application/json",
"Content-Type": "application/json; charset=UTF-8"
} : {
'Token': token,
'X-Requested-With': 'XMLHttpRequest',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
dataType: 'json',
}
let promise = new Promise(function(resolve, reject) {
uni.request(httpDefaultOpts).then(
(res) => {
resolve(res[1])
}
).catch(
(response) => {
reject(response)
}
)
})
return promise
};

export default {
baseUrl,
httpRequest,
httpTokenRequest    
}

2.将http.js引入

import http from '@/components/utils/http.js';

let opts={
                        url: '/api/device/add',
                        method: 'post'
                    };
                    let param={
                        deviceId:this.deviceCode,
                        deviceName:this.deviceName
                    };
                    http.httpTokenRequest(opts, param).then(res => {
                        console.log(res.data);
                       //打印请求返回的数据
                        
                    },error => {console.log(error);})
