背景
之前小程序代码混乱，所以新项目一开始就准备弄个微信小程序的 request 的封装
httpUtils.js
{
wx.request({//后台请求
url: API_BASE_URL + path,header: header,method: method,data: data,success: function (res) {
if (res.code) {
reject(res.data)
} else {
resolve(res.data)
}
},fail: function (res) {
reject("not data");
}
});
});
};
userLogin.js
{
wx.login({
success: res => {
let code = res.code;
// 已经授权，可以直接调用 getUserInfo 获取头像昵称，不会弹框
wx.getUserInfo({
withCredentials: true,success: res => {
let userInfo = res.userInfo;
let name = userInfo.nickName;
let avatar = userInfo.avatarUrl;
let sex = userInfo.gender;
let data = {
code: code,encryptedData: res.encryptedData,iv: res.iv,name: name,avatar: avatar,sex: sex,from: FROM,};
request("/api/user_login/byWeChatApplet","POST",data).then( (res)=>{
if (!res.code) {
try {
wx.setStorageSync(USER_ID_KEY,res.user_id);
wx.setStorageSync(TOKEN_KEY,res.token)
} catch (e) {
reject(JSON.stringify(e));
}
}
resolve(res)
}).catch( (errMsg)=>{
reject(errMsg)
});
},fail: function (res) {
if (res.errMsg && res.errMsg.startsWith("getUserInfo:fail") && res.errMsg.search("unauthorized") !== -1) {
reject("getUserInfo:fail");
return;
}
wx.getSetting({
success: (res) => {
if (!res.authSetting["scope.userInfo"]) {//没授权
showModal('提示','需要获取用户的权限,点击确定前往设置,打开用户信息',true,function (res) {
wx.openSetting({
success: (res) => {
// 用户返回 不管是否开启 接着去重新登录
login().then( (res)=>{
if (res.code) {
reject(res.message);
return
}
try {
wx.setStorageSync(USER_ID_KEY,res.user_id);
wx.setStorageSync(TOKEN_KEY,res.token)
} catch (e) {
reject(JSON.stringify(e));
}
resolve(res)
}).catch( (errMsg)=>{
reject(errMsg)
});
}
})
},function () {})
}
}
});
}
})
}
})
});
};
