httpUtils.js
const request = function (path, method, data, header) {
let user_id = "";
let token = "";
try {
user_id = wx.getStorageSync(USER_ID_KEY);
token = wx.getStorageSync(TOKEN_KEY);
} catch (e) {}
header = header || {};
let cookie = [];
cookie.push("USERID=" + user_id);
cookie.push("TOKEN=" + token);
cookie.push("device=" + 1);
cookie.push("app_name=" + 1);
cookie.push("app_version=" + ENV_VERSION);
cookie.push("channel=" + 1);
header.cookie = cookie.join("; ");
return new Promise((resolve, reject) => {
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
const login = function () {
try {
wx.removeStorageSync(USER_ID_KEY);
wx.removeStorageSync(TOKEN_KEY)
} catch (e) {}
return new Promise((resolve, reject) => {
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 () {})
}
}
});
}
})
}
})
});
