Development Of Photo Printing System Based On WeChat Public Platform

Now almost all the mobile devices have been equipped with video camera, and people more and more like taking pictures, photography. However, people must take time to manage their photos due to the limited memory space and they may even lose their photos if their phones lost. Also, photos in their phones are virtual, because they can't be mailed and collected. Therefore, people's demand for printing and collecting photos has become increasingly intense. Now there are two ways to print photos: print in photo gallery or on the online stores. Nevertheless, both have some drawbacks. If people choose the photo gallery, they have to take time to find the photo shop first, and pick them up after they have been washed. Moreover, it is difficult to make changes to the pictures, which is obviously in contrast with the Internet thinking. If people choose the online stores, they can print photos just stay at home, but the steps are complicated. Because most of the customers store their photos in their phones, that means they must import photos to a computer first, this requires higher for people's environment and equipment. Similarly, photos can't be cut or done with other operations. Obviously, this way of photo printing needs to be improved. Based on this background, my system is committed to developing a photograph printing system easy to be used.The paper studied the differences between different types of wechat public platform and designed a mechanism to reply users' messages automatically and let printing photos by users themselves become true. It also studied a number of cloud storage vendor capabilities, selected a reasonable storage vendor, designed and implemented a simple and efficient method with cloud storage to break through wechat's anti-hotlinking restriction, so that the wechat application can use the photos directly which users upload through wechat. This paper also designed and implemented a flexible, efficient technical solutions with server browser technology to merge pictures on server-side which can improve the efficiency of photo printing. In the end, it summed up an Internet photo printing solution, and developed a wechat application to print photos online. The followings are the main functions of the system. First, mobile phone users concern about the public wechat platform, send different messages to the number and then they will get automatic reply from the system, because the system can automatically reply according to the format of messages. This way can achieve the purpose of self-using the software. Second, users can upload photos they like, view the photos online, cut the photos, edit texts of every photo, and do other customization operations. Third, when finish the customization operations of their photos, users can select the pictures they like and make an order, and then complete the online payment in a third-party platform. At last, a backstage is provided to staff where they can view and manage orders easily and they can export, merge all the pictures of every orders to print.The system is based on wechat public platform development and is in the form of wechat public platform. This form has many advantages. Users having a wechat account can directly concern the wechat public number and print photos. They do not need to download additional applications. All the operations can be completed on the phone and do not need to import photos to a computer. The user education need a very small price, because wechat users' operating habits have been developed. And it needs a very small marketing cost because the wechat public platform itself has an advantage of marketing spread.The system is developed on the LNMP development environment and accesses to the wechat public platform and some third-party payment platforms. It uses a cloud storage platform for photo processing and systems accelerating to improve access rate. The system implements the functions of image cropping, image merge, image compression, ordering, background system and finally creates a photo printing application which is simple used and innovative.
