网上有很多二维码在线生成程序，不过都是生成标准的二维码，最近的一个项目要求生成中间是小图标（LOGO）的二维码，后经不断查询资料，终于做出来了，主要核心是使用了国外的一个开源类库——QRCODE，生成确实方便，希望能为大家提供一份参考。-There are many online online two-dimensional code generation program, but are generated standard two-dimensional code, a recent project requires the generation in the middle is a small icon (LOGO) two-dimensional code, after constantly poll the data, and finally did come out, the main the core is the use of an open source library QRCODE overseas, generating really convenient, hoping to provide a reference for everyone.
