小小感言
本來是想寫博客來著阿迈，朋友說簡書的排版更好些畏陕，于是就來試試。
總想著把自己開發(fā)中遇到的技術(shù)點(diǎn)仿滔、問題還有大大小小的坑都總結(jié)出來惠毁，但就是一直沒有時(shí)間寫，或者可能是自己沒有養(yǎng)成寫的好習(xí)慣并堅(jiān)持下去吧崎页，平常也就是在備忘錄鞠绰、文檔里那么隨便一記，以后得好好改進(jìn)了飒焦。
這篇文章我就總結(jié)一下自己網(wǎng)絡(luò)請(qǐng)求和上傳數(shù)據(jù)的時(shí)候用到的afn3.0
AFNetworking 介紹
AFNetworking 1.0是建立在NSURLConnection的基礎(chǔ)API上的 蜈膨，AFNetworking 2.0開始使用NSURLConnection的基礎(chǔ)API ，以及較新基于NSURLSession的API的選項(xiàng)牺荠。 AFNetworking 3.0現(xiàn)已完全基于NSURLSession的API翁巍，這降低了維護(hù)的負(fù)擔(dān)，同時(shí)支持蘋果增強(qiáng)關(guān)于NSURLSession提供的任何額外功能休雌。由于Xcode 7中灶壶，NSURLConnection的API已經(jīng)正式被蘋果棄用。雖然該API將繼續(xù)運(yùn)行杈曲，但將沒有新功能將被添加驰凛，并且蘋果已經(jīng)通知所有基于網(wǎng)絡(luò)的功能胸懈，以充分使NSURLSession向前發(fā)展。
AFNetworking 3.0正式支持的iOS 7恰响， Mac OS X的10.9趣钱， watchOS 2 ， tvOS 9 和Xcode 7胚宦。
在AFNetworking3.0中下面這些類已被廢棄：
- AFURLConnectionOperation
- AFHTTPRequestOperation
- AFHTTPRequestOperationManager
另外這些類包含基于NSURLConnection的API的內(nèi)部實(shí)現(xiàn)首有，他們已經(jīng)被使用NSURLSession重構(gòu)：
- UIImageView+AFNetworking
- UIWebView+AFNetworking
- UIButton+AFNetworking
Post請(qǐng)求
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer.timeoutInterval= 20;
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/json",@"application/json",@"text/javascript",@"text/html", @"application/javascript", @"text/js", nil];
AFSecurityPolicy *securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone];
securityPolicy.allowInvalidCertificates = YES;
manager.securityPolicy = securityPolicy;
[manager POST:urlStr parameters:dic success:^(NSURLSessionTask *task, id responseObject) {
NSLog(@"請(qǐng)求成功");
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(@"%@ error" , error);
}];
Get請(qǐng)求
因?yàn)轫?xiàng)目里用到的都是post請(qǐng)求，get請(qǐng)求我就簡單的附上
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:URL parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(@"請(qǐng)求成功");
}
failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@",error);
}];
上傳圖片
-(void)PostUploadImage:(NSMutableDictionary*)dic Url:(NSString *)url
{
UIImage *image = [dic valueForKey:@"pic"];//圖片以鍵值對(duì)的形式存為了一個(gè)字典
NSData *data =UIImageJPEGRepresentation(image , 0.5);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:data];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (error) {
NSLog(@"%@error" , error);
}else{
NSString *str = [[ NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *dic = [ NSDictionary dictionary];
dic = [self dictionaryWithJsonString:str];
self.Block(dic);//返回?cái)?shù)據(jù)
}
}];
[dataTask resume];
}

上傳多張圖片
-(void)POSTuploadImages:(NSArray*)imageArray url:(NSString*)url

NSData *uploadImage = imageArray[i];//數(shù)組里存儲(chǔ)的已經(jīng)將UIImage轉(zhuǎn)化為了NSData
// 上傳的參數(shù)名
NSString * Name = [NSString stringWithFormat:@"%d",i+1];
// 上傳filename
NSString * fileName = [NSString stringWithFormat:@"%@.png", Name];
[formData appendPartWithFileData:uploadImage name:Name fileName:fileName mimeType:@"image/png"];
}
} error:&error];
// 可在此處配置驗(yàn)證信息
// 將 NSURLRequest 與 completionBlock 包裝為 NSURLSessionUploadTask
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLSessionUploadTask *uploadTask =[manager uploadTaskWithStreamedRequest:request progress:nil completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
NSString *str = [[ NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding];
NSDictionary *dic = [ NSDictionary dictionary];
dic = [self dictionaryWithJsonString:str];
NSLog(@"%@===========",dic);//最終的數(shù)據(jù)
self.Block(dic);//使用block返回?cái)?shù)據(jù)
}];
}
上傳錄音文件
-(void)POSTuploadSound:(NSMutableDictionary*)dic url:(NSString*)url
{
NSData *data= [dic valueForKey:@"Sound"];
