IOS开发之AFNetworking开源库的使用

1.简介

　　常见的处理网络请求方式

　　(1)NSURLConnection/NSURLsession

　　(2)ASIHttPRequest 早期项目中比较常见, 由于作者不更新了

　　(3)AFNetworking 推荐使用, 项目中使用

　　(4)MKNetworkKit 试试

2.配置和使用

　　2.1 配置

　　　　库文件拖入工程中, 包含头文件

　　　　#import "AFNetworking.h"

　　2.2 使用

　　　　2.2.1.GET请求（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";        //定义AFNetworking管理    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];        //注意：默认数据是JSON，content-type也是JSON，responSEObject是解析字典和数组，不是产生错误Code=-1016    //解决:设置解析器为HTTP形式，下载回来是NSData    manager.responseSerializer = [AFCompoundResponseSerializer serializer];        [manager GET:urlstring parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {//        responseObject重要参数，包含下载数据//        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请求

-(void)testPostRequest{    //POST接口:    //参数1:@"user" : @"quiet"    //参数2:@"passWord" : @"123"        NSString *urlString = @"http://quiet.local/testdir/login.php";        AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    manager.responseSerializer = [AFCompoundResponseSerializer serializer];        //参数1:传入地址    //参数2:传入URL请求的参数，格式传入字典    [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.上传文件（上传图片）

-(void)testUploadFile{        //POST上传的接口    NSString *urlString = @"http://quiet.local/uploadtest/pk.php";    //参数名:image : 参数值是图片    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) {                //实现:上传的数据附加到请求体中        //fileName:上传后的文件名        //mimeType:需要上网搜索mime，把相应的格式复制过来        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.下载文件

-(void)testDownloadFile{    NSString *urlString = @"http://imgcache.QQ.com/club/item/avatar/zip/7/i87/all.zip";        //创建会话管理对象（通过默认配置）    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(@"下载完成");    }];        //启动任务    [task resume];    }

testDownloadFile

　　　　 2.2.5.监控网络状态

-(void)testMonitorNetworkStatus{        AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:@"www.baidu.com"]];    [manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {        NSDictionary *dict = @{            @(AFNetworkReachabilityStatusUnknown): @"未知",            @(AFNetworkReachabilityStatusNotReachable): @"不可达",            @(AFNetworkReachabilityStatusReachableViaWWAN): @"GPRS",            @(AFNetworkReachabilityStatusReachableViaWiFi): @"Wifi",            };        NSLog(@"状态为 %@",dict[@(status)]);            }];    //开启状态监视    [manager.reachabilityManager startMonitoring];}
