IOS開發之AFNetworking開源庫的使用

1.簡介

　　常見的處理網絡請求方式

　　(1)NSURLConnection/NSURLsession

　　(2)ASIHttPRequest 早期項目中比較常見, 由于作者不更新了

　　(3)AFNetworking 推薦使用, 項目中使用

　　(4)MKNetworkKit 試試

2.配置和使用

　　2.1 配置

　　　　庫文件拖入工程中, 包含頭文件

　　　　#import "AFNetworking.h"

　　2.2 使用

　　　　2.2.1.GET請求（html，json，xml）

-(void)testGetRequest{        NSString *urlstring = @"http://www.baidu.com";    urlstring = @"http://m.weather.com.cn/data/101010100.html";    urlstring = @"http://mp.manzuo.com/china/beijing/home_2.xml";        //定義AFNetworking管理    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];        //注意：默認數據是JSON，content-type也是JSON，responSEObject是解析字典和數組，不是產生錯誤Code=-1016    //解決:設置解析器為HTTP形式，下載回來是NSData    manager.responseSerializer = [AFCompoundResponseSerializer serializer];        [manager GET:urlstring parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {//        responseObject重要參數，包含下載數據//        NSLog(@"o = %@",responseObject);                NSString *str = [[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding];        NSLog(@"str = %@",str);            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error = %@",error);    }];}

testGetRequest

　　　　 2.2.2.POST請求

-(void)testPostRequest{    //POST接口:    //參數1:@"user" : @"quiet"    //參數2:@"passWord" : @"123"        NSString *urlString = @"http://quiet.local/testdir/login.php";        AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    manager.responseSerializer = [AFCompoundResponseSerializer serializer];        //參數1:傳入地址    //參數2:傳入URL請求的參數，格式傳入字典    [manager POST:urlString parameters:@{@"user": @"quiet",@"password" : @"123"} success:^(AFHTTPRequestOperation *operation, id responseObject) {         NSString *str = [[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding];        NSLog(@"str = %@",str);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error = %@",error);    }];}

testPostRequest

　　　　2.2.3.上傳文件（上傳圖片）

-(void)testUploadFile{        //POST上傳的接口    NSString *urlString = @"http://quiet.local/uploadtest/pk.php";    //參數名:image : 參數值是圖片    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    manager.responseSerializer = [AFCompoundResponseSerializer serializer];        [manager POST:urlString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {        NSString *path = [[NSBundle mainBundle]pathForResource:@"daji.jpg" ofType:nil];                [formData appendPartWithFileURL:[NSURL URLWithString:path] name:@"image" fileName:@"666.jpg" mimeType:@"image/jpeg" error:nil];    } success:^(AFHTTPRequestOperation *operation, id responseObject) {        NSString *str = [[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding];        NSLog(@"str = %@",str);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {         NSLog(@"error = %@",error);    }];            [manager POST:urlString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {                //實現:上傳的數據附加到請求體中        //fileName:上傳后的文件名        //mimeType:需要上網搜索mime，把相應的格式復制過來        NSString *path = [[NSBundle mainBundle]pathForResource:@"daji.jpg" ofType:nil];            [formData appendPartWithFileURL:[NSURL fileURLWithPath:path] name:@"image" fileName:@"666.jpg" mimeType:@"image/jpeg" error:nil];                } success:^(AFHTTPRequestOperation *operation, id responseObject) {        NSString *str = [[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding];        NSLog(@"str = %@",str);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error = %@",error);    }];    }

testUploadFile

　　　　 2.2.4.下載文件

-(void)testDownloadFile{    NSString *urlString = @"http://imgcache.QQ.com/club/item/avatar/zip/7/i87/all.zip";        //創建會話管理對象（通過默認配置）    AFURLSessionManager *manager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];    NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]] progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {                //返回文件保存的位置        NSString *path = [NSString stringWithFormat:@"%@/Documents/all.zip",NSHomeDirectory()];        NSLog(@"%@",NSHomeDirectory());        return [NSURL fileURLWithPath:path];            } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {        NSLog(@"下載完成");    }];        //啟動任務    [task resume];    }

testDownloadFile

　　　　 2.2.5.監控網絡狀態

-(void)testMonitorNetworkStatus{        AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:@"www.baidu.com"]];    [manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {        NSDictionary *dict = @{            @(AFNetworkReachabilityStatusUnknown): @"未知",            @(AFNetworkReachabilityStatusNotReachable): @"不可達",            @(AFNetworkReachabilityStatusReachableViaWWAN): @"GPRS",            @(AFNetworkReachabilityStatusReachableViaWiFi): @"Wifi",            };        NSLog(@"狀態為 %@",dict[@(status)]);            }];    //開啟狀態監視    [manager.reachabilityManager startMonitoring];}
