登录从0到1：不文明现象随手拍小程序开发日记（一）
前期调研
不文明现象随手拍小程序：在城市的快速发展进程中，不文明现象时有发生，为了有效解决这一问题，提升城市文明程度， 市民若发现不文明行为，如乱扔垃圾、随地吐痰、破坏公共设施、违规停车等，只需点击“上报不文明现象”按钮，即可将这些不文明行为记录下来，并附上简短的文字描述，如事件发生的具体地点、时间以及对周围环境或他人造成的影响等。市民可以在小程序的“我的上报记录”页面中随时查看自己的上报; 为了进一步调动市民参与的积极性，小程序设置了积分激励机制。每当市民成功上报一条不文明现象并被后台审核通过后，即可获得相应的积分奖励。 同时提供积分商城模块，可以让市民使用通过参与任务所获得的积分来兑换各种奖励或福利。
