AFNetworking是一個(gè)輕量級(jí)的iOS網(wǎng)絡(luò)通信類庫(kù)朱庆。它建立在NSURLConnection之上
注：AFNetworking 依賴包：UIKit , SystemConfiguration,MobileCoreServices,Security ?;AFNetworking 2.5版本以后，需要Xcode 6.3以上才支持
默認(rèn)提交請(qǐng)求的數(shù)據(jù)是二進(jìn)制的,返回格式是JSON如果提交數(shù)據(jù)是JSON的,需要將請(qǐng)求格式設(shè)置為AFJSONRequestSerializer
請(qǐng)求格式：
AFHTTPRequestSerializer????????????二進(jìn)制格式
AFJSONRequestSerializer????????????JSON
AFPropertyListRequestSerializer????PList(是一種特殊的XML,解析起來(lái)相對(duì)容易)
返回格式：
AFHTTPResponseSerializer???????????二進(jìn)制格式
AFJSONResponseSerializer???????????JSON
AFXMLParserResponseSerializer??????XML,只能返回XMLParser,還需要自己通過(guò)代理方法解析
AFXMLDocumentResponseSerializer?(Mac?OS?X)
AFPropertyListResponseSerializer???PList
AFImageResponseSerializer??????????Image
AFCompoundResponseSerializer???????組合

GETRequest
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManagermanager];
[managerGET:@"http://example.com/resources.json"parameters:nilsuccess:^(AFHTTPRequestOperation *operation,idresponseObject) {NSLog(@"JSON:%@", responseObject);}failure:^(AFHTTPRequestOperation *operation,NSError*error) {NSLog(@"Error:%@", error);}];
POSTURL-Form-Encoded Request
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManagermanager];NSDictionary*parameters = @{@"foo":@"bar"};[managerPOST:@"http://example.com/resources.json"parameters:parameterssuccess:^(AFHTTPRequestOperation *operation,idresponseObject) {NSLog(@"JSON:%@", responseObject);}failure:^(AFHTTPRequestOperation *operation,NSError*error) {NSLog(@"Error:%@", error);}];
POSTMulti-Part Request —— 多文件上傳闷祥，建議用AFURLSessionManager
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManagermanager];AFURLSessionManagerNSDictionary*parameters = @{@"foo":@"bar"};NSURL*filePath = [NSURLfileURLWithPath:@"file://path/to/image.png"]; [managerPOST:@"http://example.com/resources.json"parameters:parametersconstructingBodyWithBlock:^(id formData) { [formDataappendPartWithFileURL:filePathname:@"image"error:nil]; }success:^(AFHTTPRequestOperation *operation,idresponseObject) {NSLog(@"Success:%@", responseObject); }failure:^(AFHTTPRequestOperation *operation,NSError*error) {NSLog(@"Error:%@", error); }];
Creating an Upload Task ?—— 上傳磁盤上的文件娱颊，使用uploadTaskWithRequest方式，需要指定fromFile的位置(這種方式從磁盤加載凯砍，降低內(nèi)存的使用)箱硕，request中不封裝上傳文件
AFURLSessionManager*manager = [[AFURLSessionManageralloc]initWithSessionConfiguration:[NSURLSessionConfigurationdefaultSessionConfiguration]];
NSURL*url = [NSURLURLWithString:@"http://www.freeimagehosting.net/upload.php"];
//創(chuàng)建request，設(shè)置屬性
NSMutableURLRequest* request = [NSMutableURLRequestrequestWithURL:url];
// ? application/json
[requestaddValue:@"image/png”forHTTPHeaderField:@"Content-Type"];
[requestaddValue:@"application/json”forHTTPHeaderField:@"Accept"];
[requestsetHTTPMethod:@"POST"];
[requestsetCachePolicy:NSURLRequestReloadIgnoringCacheData];
[requestsetTimeoutInterval:60];
NSProgress*progress =nil;//上傳進(jìn)度
//創(chuàng)建本地文件路徑悟衩，這里不從內(nèi)存取數(shù)據(jù)剧罩，直接讀取磁盤，減少內(nèi)存使用
NSString*path = ? [[NSBundlemainBundle]pathForResource:@"qqq"ofType:@"png"];
NSURL* local_url = [NSURLfileURLWithPath:path];
NSURLSessionUploadTask*uploadTask = [manageruploadTaskWithRequest:requestfromFile:local_urlprogress:&progresscompletionHandler:^(NSURLResponse*response,idresponseObject,NSError*error) {
if(error) {
NSLog(@"Error: %@", error);
}else{

}
}];
//對(duì)進(jìn)度添加監(jiān)聽(tīng)座泳，并實(shí)時(shí)更新進(jìn)度條

Creating an Upload Task —— Stream方式上傳文件惠昔，速度和uploadTaskWithRequest差不多幕与，request里需要封裝formData
//在request里封裝formData信息；
NSMutableURLRequest*request = [[AFHTTPRequestSerializerserializer]multipartFormRequestWithMethod:@"POST"URLString:@"http://www.freeimagehosting.net/upload.php"parameters:nilconstructingBodyWithBlock:^(id formData) {
UIImage*img = [UIImageimageNamed:@"qqq"];
NSData*imageData =UIImagePNGRepresentation(img);
//一定要指定mimeType
//appendPartWithFileData：從內(nèi)存中加載附件镇防，也可以用appendPartWithFileURL：從磁盤加載附件
[formDataappendPartWithFileData:imageDataname:@"file"fileName:@"qqq.jpg"mimeType:@"image/png"];
}error:nil];
//進(jìn)度
NSProgress*progress =nil;
AFURLSessionManager*manager = [[AFURLSessionManageralloc]initWithSessionConfiguration:[NSURLSessionConfigurationdefaultSessionConfiguration]];
NSURLSessionUploadTask*uploadTask = [manageruploadTaskWithStreamedRequest:requestprogress:&progresscompletionHandler:^(NSURLResponse*response,idresponseObject,NSError*error) {

NSLog(@"%@ %@", response, responseObject);
}
}];
//監(jiān)聽(tīng)上傳進(jìn)度

Creating a Data Task ? —— 下載data任務(wù)（音樂(lè)、視頻来氧、網(wǎng)頁(yè)等文件）
AFURLSessionManager*manager = [[AFURLSessionManageralloc]initWithSessionConfiguration:[NSURLSessionConfigurationdefaultSessionConfiguration]];
NSURL*URL = [NSURLURLWithString:@"http://blog.csdn.net/majiakun1/article/details/38133703”];
