基于AFNetWorking封装一个网络请求数据的类
1.新建一个继承于NSObject类的类，在.h文件中
#import "AFHTTPRequestOperationManager.h"
//定义两个block来接收请求成功和失败
typedef void(^DownLoadFinishedBlock)(id responseObj);
typedef void (^DownLoadFialedBlock)(NSError*error);
@interface NetManager : NSObject
//Get请求的方法封装
+(void)doGetWithUrlStr:(NSString*)urlString contentType:(NSString*)type finished:(DownLoadFinishedBlock)finished failure:(DownLoadFialedBlock)fialed;
//Post请求的方法封装
+(void)doPostWithUrlStr:(NSString*)urlString parameters:(NSDictionary*)dic contentType:(NSString*)type finished:(DownLoadFinishedBlock)finished failure:(DownLoadFialedBlock)fialed;
2.下面是封装方法的实现：
#import "NetManager.h"
@implementation NetManager
//Get请求的方法
+(void)doGetWithUrlStr:(NSString*)urlString contentType:(NSString*)type finished:(DownLoadFinishedBlock)finished failure:(DownLoadFialedBlock)fialed{
//创建manager对象
AFHTTPRequestOperationManager * manager = [AFHTTPRequestOperationManager manager];
//设置请求的数据类型
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:type, nil];
[manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
//请求成功
finished(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//请求失败
fialed(error);
}];
}
//Post请求的方法
//说明：parameters：参数,即使用post请求时需要传给后台服务器的参数，在这里我们应封装成一个字典类型的数据，然后把这个字典当做参数传过去。
+(void)doPostWithUrlStr:(NSString*)urlString parameters:(NSDictionary*)dic contentType:(NSString*)type finished:(DownLoadFinishedBlock)finished failure:(DownLoadFialedBlock)fialed
{
//创建manager对象
AFHTTPRequestOperationManager * manager = [AFHTTPRequestOperationManager manager];
//设置请求的数据类型
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:type, nil];
[manager POST:urlString parameters:dic success:^(AFHTTPRequestOperation *operation, id responseObject) {
finished(responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
fialed(error);
}];
}
@end
