uniapp怎么实现选择和上传图片分开

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了uniapp怎么实现选择和上传图片分开相关的知识，希望对你有一定的参考价值。
参考技术A 打开HBuilderX开发工具，创建uniapp项目，绑定点击事件即可。在methods中，定义点击事件，调用api中的unichooseImage。在上传照片的API中，请求成功后调用unigetImageInfo，获取图片信息。在获取图片方法下方，调用uni previewImage，预览图片。保存代码并运行到小程序模拟器，查看界面显示效果。
uniapp是一个使用Vuejs开发所有前端应用的框架，开发者编写一套代码，可发布到ios、android、Web（响应式）、以及各种小程序、快应用等多个平台。
