获取用户信息及获取

//app.js 获取
getUserInfo: function (cb) {
    var that = this
    if (this.globalData.userInfo) {
      typeof cb == "function" && cb(this.globalData.userInfo)
    } else {
      //调用登录接口
      wx.login({
        success: function (response) {
          console.info('response', response)
          wx.getUserInfo({
            success: function (res) {
              console.info('res', res)
              that.globalData.userInfo = res.userInfo
              typeof cb == "function" && cb(that.globalData.userInfo)
            }
          })
        }
      })
    }
  },
  globalData: {
    userInfo: null,
    domain: 'https://www.somethingwhat.com',
    localStorage: {
      style: {},
      usage: {
        //lastreadurl: '',
        //lastreadchaptername: '',
        //lastreadbookname: '',
        history: []
      }
    }
//index.js 获取
var app = getApp()
Page({
  data: {
    motto: '',
    userInfo: {}
  },
  onLoad: function () {
    console.log('onLoad')
    wx.showShareMenu()
    var that = this
    //调用应用实例的方法获取全局数据
    app.getUserInfo(function (userInfo) {
      //更新数据
      that.setData({
        userInfo: userInfo
      })
    }) 
  }
})

###form提交及获取数据

 <form bindsubmit="formSubmit">
      <input class="weui-search-bar__input input-search" maxlength="20" confirm-type="search" bindconfirm="confirmEvent" name="s_name" placeholder="请输入小说名称" />
      <button class="input-btn" type="primary" size="mini" hover-class="other-button-hover" formType="submit">搜索</button>
    </form>

 //提交
  formSubmit: function (e) {
    console.info('formSubmit')
    var _txt = e.detail.value.s_name.trim();
    if (_txt != '') {
      this.redirectFunc(encodeURIComponent(_txt));
    }
  }

###保存图片

wx.downloadFile({
          url: imgSrc,
          success: function (res) {
              console.log(res);
              //图片保存到本地
              wx.saveImageToPhotosAlbum({
                  filePath: res.tempFilePath,
                  success: function (data) { 
                      wx.showToast({
                          title:'保存成功',
                          icon: 'success',

###php后台模拟请求微信接口

/* 发送json格式的数据，到api接口 -xzz0704  */
    function https_curl_json($url,$data,$type){
        if($type=='json'){//json $_POST=json_decode(file_get_contents('php://input'), TRUE);
            $headers = array("Content-type: application/json;charset=UTF-8","Accept: application/json","Cache-Control: no-cache", "Pragma: no-cache");

        }else{
			$headers = array("Content-type: application/x-www-form-urlencoded;charset=UTF-8","Accept: application/json","Cache-Control: no-cache", "Pragma: no-cache"); 
		}
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        if (!empty($data)){
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS,$data);
        }
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl, CURLOPT_HTTPHEADER, $headers );
        $output = curl_exec($curl);
        if (curl_errno($curl)) {

        }
