一般我们习惯将请求接口的方法统一起来,变成公共方法
但是在小程序中,似乎遇到了一些问题,官方给的示例是:
this.setData({
name: ‘MINA‘
})
this局限了请求的地方,似乎只能在每个业务页面内,setData方法的参数不够配置化
以下是我参考一些资料之后得到的解决方案
util.js
var apiHost = ".....";
//url添加最后的相对路径即可
function getRequest(url, that, targetName) {
wx.request({
url: apiHost + url,
method: ‘GET‘,
header: {
‘content-type‘: ‘application/json‘ // 默认值
},
success: function (res) {
var param = {};
param[targetName] = res.data;
that.setData(param);
},
fail: function (error) {
console.log(error);
}
})
}
function postRequest(url, data, that, targetName ) {
var token=‘你的令牌‘; //比如存储在Storage中
wx.request({
url: apiHost + url,
data: data,
method: ‘POST‘,
header: {
‘content-type‘: ‘application/json‘, // 默认值
‘Authorization‘: "Bearer " + token
},
success: function (res) {
var param = {};
param[targetName] = res.data;
that.setData(param);
},
fail: function (error) {
console.log(error);
}
})
}
module.exports.getRequest = getRequest;
module.exports.postRequest = postRequest;
调用api
const util = require(‘../../utils/util.js‘)
Page({
data: {
logInResult:{},
sessionKey:"",
},
logIn:function(e){
//登录某系统
util.postRequest(‘/Account/LogInForMiniProgram‘, { "UserName": this.data.userName, "Password": this.data.password }, this, "logInResult");
},
wxLogInAndGetSessionKey: function (e) {
//注意作用域,此处,在wx的方法里面拿到的this不对(http://jsrocks.org/cn/2014/10/arrow-functions-and-their-scope)
var that = this;
wx.login({
success: function (res) {
console.log(res)
if (res.code) {
//调用后端接口获得sessionkey
util.postRequest(‘/AccountForMiniProgram/WechatGetSessionKey‘, { id: res.code }, that, "sessionKey");
} else {
console.log(‘登录失败!‘ + res.errMsg)
}
}
});
},
onLoad: function () {
}
})
