微信小程序简单教程3

二十三 关闭应用调试
打开 application/config.php 配置文件
'app_debug' => Env::get('app.debug', false),

二十四 编辑微信接口

 /**
 * 中药一览
 * @ApiTitle    (中药一览)
 * @ApiMethod   (POST)
 */
public function medic_list()
{
    $name = $this->request->post("name");
    //$request = Config::get('upload');//static固定方法
    //$medic = new Medic();//非固定方法需先实例化对象
    //$request = $medic->index('name',$name);
    $data = Db::table('medic')->where('name', $name)->find();//单条指定数据
    $this->success('success', $data);
}

二十五 测试接口
php think api --force=true
https://访问域名/api.html
https://admin.huchangyi.com/api/api_wechat/medic_list

二十六 小程序中调用接口wx.request
self = this;

    wx.request({
        url: 'https://admin.huchangyi.com/api/api_wechat/medic_list', 
        method: 'POST',
        data: {
            'name': name,
        },
        header: {
          'content-type': 'application/json' // 默认值
        },
        success (res) {
          //console.log(res.data),
          json = res.data.data,
          json = JSON.stringify(json),
          json = JSON.parse(json),
          console.log(json);
          if(json!=null){
            self.setData({
                inputValue: e.detail.value,
                name:json['name'],
                class:json['class'],
                alias:json['alias'],
                form:json['form'],
                habitat:json['habitat'],
                mining:json['mining'],
                chemical:json['chemical'],
                taste:json['taste'],
                effect:json['effect'],
                apply:json['apply'],
                mix:json['mix'],
                pinyin:json['pinyin'],
                phr:json['phr'],
              });
          }
          else{
            self.setData({
                inputValue: e.detail.value,
                name:'无匹配中药名称，请重新输入',
                class:'',
                alias:'',
                form:'',
                habitat:'',
                mining:'',
                chemical:'',
                taste:'',
                effect:'',
                apply:'',
                mix:'',
                pinyin:'',
                phr:'',
              });
          }
        },
        fail (errMsg) {
            console.log(errMsg.data)
          }
      });
