IOS開發之AFNetworking開源庫的使用1.簡介

　　常見的處理網路請求方式

　　(1)NSURLConnection/NSURLSession

　　(2)ASIHttpRequest 早期項目中比較常見, 由於作者不更新了

　　(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 

　　　　庫檔案拖入工程中, 包含標頭檔 

　　　　#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：預設資料是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:設定解析器為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，包含下載資料// 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介面: //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.上傳檔案（上傳圖片）-(void)testUploadFile{ //POST上傳的介面 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:上傳的資料附加到請求體中 //fileName:上傳後的檔案名稱 //mimeType:需要上網搜尋mime，把相應的格式複製過來 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.下載檔案-(void)testDownloadFile{ NSString *urlString = @"http://imgcache.qq.com/club/item/avatar/zip/7/i87/all.zip"; //建立會話管理對象（通過預設配置） AFURLSessionManager *manager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; NSURLSessionDownloadTask *task = [manager downloadTaskWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]] progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { //返迴文件儲存的位置 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.監控網路狀態-(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];}testMonitorNetworkStatus 　　　　2.2.6.圖片非同步功能（替代SDWebImage）

    　　　　　　匯入標頭檔

　　　　　　　　　　#import "UIKit+AFNetworking.h"

    　　　　　　- (void)setImageWithURL:(NSURL *)url;

 　　　　2.2.7.有一些特殊的要求標頭

    　　　　 BAIDU_WISE_UID=wapp_1428385381699_466;

　　    　　 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];　　

　　   　　  [manager.requestSerializer setValue:@"wapp_1428385381699_466" forHTTPHeaderField:@"BAIDU_WISE_UID"];
