摘要
3G网络的普及推动了车载定位行业的发展,由此衍生了大量车载定位数据供用户查询、下载.PDF文件将文字、图像等封装在一个文件中,集成性和安全可靠性都较高,使其成为在Internet上进行电子文档发行和数字化信息传播的理想文档格式.以Django作为客户端软件设计平台,服务器端接收客户端发送的操作指令,并进行相应操作:查询数据库,筛选数据,用reportlab插件生成带表格的PDF文件,最后将数据流发送回客户端,实现下载.
The popularity of 3G networks promote the development of the industry of vehicle localization system. Therefore, it leads to a large number of data for users to query and download. PDF file can encapsulate the texts and images into one file. It has high integration, security and reliability. This character makes it to be an ideal document format for electronic document distribution and digital information propagation on the Internet . Here, the Django platform is used as the client software platform. The server will receive operating instructions from the clients and carry out the corresponding operations：querying the database, filtering the data, generating PDF files with form through reportlab plug-in. Finally, the data stream will be sent back to the clients and support users to download.
