AFNetworking大家都不陌生，本文对其进行了最简单的封装，功能实现：GET、POST、单文件上传、多文件上传、文件下载。
AFNetworking实现GET、POST、上传、下载功能简单封装
先用java Spring Boot模拟实现后台接口
对后台不懂的同学可以略过，模拟使用的Spring Boot实现的RestFul接口。直接上码

String fileName = strDate + imageFile.getOriginalFilename().substring(imageFile.getOriginalFilename().indexOf("."),imageFile.getOriginalFilename().length());
String realPath = httpSession.getServletContext().getRealPath("/userfiles");
System.out.println("realPath : "+realPath);
try {

}

/*

for (MultipartFile file : imageFile) {
if (file.isEmpty()) {
System.out.println("文件未上传");
} else {
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
Random random = new Random();
Date date = new java.util.Date();
String strDate = sdf.format(date);
String fileName = strDate + random.nextInt(1000) + file.getOriginalFilename().substring(file.getOriginalFilename().indexOf("."),file.getOriginalFilename().length());
String realPath = httpSession.getServletContext().getRealPath("/userfiles");
System.out.println("realPath : "+realPath);
System.out.println("fileName : "+fileName);
try {
FileUtils.copyInputStreamToFile(file.getInputStream(),new File(realPath, fileName));
} catch (IOException e) {
e.printStackTrace();
}
}
}
ResObject<Object> object = new ResObject<Object>(Constant.Code01, Constant.Msg01, user, null);
return object;
}
}
GET请求的结果如图，返回的是JSON格式数据
GET请求的结果
AFNetworking简单封装
定义SSNetworkingManager继承自AFHTTPSessionManager，并实现单利方法，此处希望有看过AF源码的同学给出建议，是用单利比较合适还是每个请求都初始化一个AFHTTPSessionManager。
