因所在公司項目久遠，網(wǎng)絡請求一直用的是ASIHTTPRequest,一步一步寫起來太麻煩卷哩，故對其封裝下洽议，廢話不多說直接上代碼：
1.引入ASI指黎，本人使用CocoaPods三方庫管理工具
platform :ios, '7.0'
target 'ASINetworking' do
pod 'ASIHTTPRequest'
......
end
2. 先創(chuàng)建一個工具類
ASIHttpUtil.h
/**
*? 請求完成回調方法
*/
typedef void (^CompleteBlock)(id json, NSString *stringData);
typedef void (^FailedBlock)(NSError *error);
typedef void (^ProgressBlock)(float progress);
/**
*? GET請求芯砸，有參數(shù)
*
*? @param path 接口路徑，不能為空
*? @param paramsDic 請求的參數(shù)的字典并淋，參數(shù)可為nil, 例如：NSDictionary *params = @{@"key":@"value"}
*? @param completeBlock 請求完成塊寓搬，返回 id JSON, NSString *stringData;
*? @param failed 請求失敗塊，返回 NSError *error;
*/
+ (ASIHTTPRequest *)getRequestWithPath:(NSString *)path params:(NSDictionary *)paramsDic completed:(CompleteBlock)completeBlock failed:(FailedBlock)failed;
/**
*? POST請求县耽，有參數(shù)句喷；
*
*? @param path 接口路徑，不能為空兔毙；
*? @param paramsDic 請求的參數(shù)的字典唾琼，參數(shù)可為nil, 例如：NSDictionary *params = @{@"key":@"value"}
*? @param completeBlock 請求完成塊，返回 id JSON, NSString *stringData;
*? @param failed 請求失敗塊澎剥，返回 NSError *error;
*
*? @return 返回ASIHTTPRequest的指針锡溯，可用于 NSOperationQueue操作

本文只針對于GET請求方法和POST請求方法做了介紹祭饭，Demo中還詳細介紹了文件上傳及下載等方法的封裝，有需要的朋友可以下載查看叙量，希望對你有所幫助倡蝙。
