基本上所有的APP都会涉及网络这块，不管是用AFNetWorking还是自己写的http请求，整个网络框架的搭建很重要。 楼主封装的网络请求类，包括自己写的http请求和AFNetWorking的请求，代码简单，主要是框架搭建。简单来说，就是一个请求类，一个解析类，还有若干数据类。 以下代码以公开的天气查询api为例： 1.网络请求类 我把常用的网络请求方法都封装好了，你只需要写自己的接口，传递apiName，params等参数就可以。 #pragmamark ios请求方式 //ios自带的get请求方式 -(void)getddByUrlPath:(NSString *)path andParams:(NSString *)paramsandCallBack:(CallBack)callback{ if(params) { [path stringByAppendingString:[NSString stringWithFormat:@"?%@",params]]; } NSString* pathStr =[path stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"url:%@",pathStr); NSURL *url =[NSURL URLWithString:pathStr]; NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:url]; NSURLSession *session =[NSURLSession sharedSession]; NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { dispatch_async(dispatch_get_main_queue(), ^{ idjsonData = [NSJSONSerialization JSONObjectWithData:data options:0error:Nil]; NSLog(@"%@",jsonData); if([jsonData isKindOfClass:[NSArray class]]) { NSDictionary* dic = jsonData[0]; callback(dic); }else{ callback(jsonData); } }); }]; //开始请求 [task resume]; } //ios自带的post请求方式 -(void)postddByByUrlPath:(NSString *)path andParams:(NSDictionary*)paramsandCallBack:(CallBack)callback{ NSURL *url =[NSURL URLWithString:path]; NSMutableURLRequest *request =[NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; NSError*error; if([NSJSONSerialization isValidJSONObject:params]) { NSData *jsonData = [NSJSONSerialization dataWithJSONObject:paramsoptions:NSJSONWritingPrettyPrinted error:&error]; [request setHTTPBody:jsonData]; NSURLSession *session =[NSURLSession sharedSession]; NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { dispatch_async(dispatch_get_main_queue(), ^{ NSString* str =[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"..........%@",str); idjsonData = [NSJSONSerialization JSONObjectWithData:data options:0error:Nil]; if([jsonData isKindOfClass:[NSArray class]]) { NSDictionary* dic = jsonData[0]; callback(dic); }else{ callback(jsonData); } }); }]; //开始请求 [task resume]; } } #pragmamark 第三方请求方式 //第三方的get请求方式 -(void)getByApiName:(NSString *)apiName andParams:(id)paramsandCallBack:(CallBack)callback{ [self.manager GET:apiName parameters:paramssuccess:^(AFHTTPRequestOperation *operation, idresponseObject) { callback(responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { callback(nil); }]; } //第三方的post请求方式 -(void)postByApiName:(NSString *)apiName andParams:(id)paramsandCallBack:(CallBack)callback{ [self.manager POST:apiName parameters:paramssuccess:^(AFHTTPRequestOperation *operation, idresponseObject) { callback(responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { callback(nil); }]; } //第三方的post上传图片请求方式 -(void)postImageByApiName:(NSString *)apiName andParams:(id)paramsandImagesArray:(NSArray*)images andBack:(CallBack)callback{ [self.manager POST:apiName parameters:paramsconstructingBodyWithBlock:^(idformData) { for(inti = 0; i<images.count; i++) { NSData* imageData = UIImageJPEGRepresentation(images[i], 0.8); NSString* name =nil; if(images.count == 1) { name = @"imageFile"; }else{ name = [NSString stringWithFormat:@"file%d",i+1]; } [formData appendPartWithFileData:imageData name:name fileName:[NSString stringWithFormat:@"image.jpg"] mimeType:@"image/jpeg"]; } } success:^(AFHTTPRequestOperation *operation, idresponseObject) { callback(responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { callback(nil); }]; } -(void)postImageByApiName:(NSString *)apiName andImageName:(NSString*)imageName andParams:(id)paramsandImage:(UIImage*)image andBack:(CallBack)callback{ NSData* imageData = UIImageJPEGRepresentation(image, 0.8); [self.manager POST:apiName parameters:paramsconstructingBodyWithBlock:^(idformData) { [formData appendPartWithFileData:imageData name:imageName fileName:[NSString stringWithFormat:@"image.jpg"] mimeType:@"image/jpeg"]; } success:^(AFHTTPRequestOperation *operation, idresponseObject) { callback(responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { callback(nil); }]; } 以天气查询为例，自己写个接口，选择请求方式： -(void)getWeatherCallBack:(CallBack)callback{ //选择需要的请求方式，我们采用非第三方的get请求，具体情况选择不同的请求方式，都是异步请求 [self getddByUrlPath:@"http://m.weather.com.cn/data/101190101.html"andParams:nil andCallBack:^(idobj) { //json解析 weather* weatherInfo =[WTParseWeather parseWeatherByWeatherDic:obj]; //返回解析后的数据 callback(weatherInfo); }]; } 2 解析类，这个不同的数据要不同的解析类，自己写，这个是天气的例子： +(weather *)parseWeatherByWeatherDic:(NSDictionary *)Dic{ NSDictionary* weatherInfoDic = [Dic objectForKey:@"weatherinfo"]; weather* weaInfo =[[weather alloc]init]; weaInfo.city = [weatherInfoDic objectForKey:@"city"]; weaInfo.date = [weatherInfoDic objectForKey:@"date_y"]; weaInfo.week = [weatherInfoDic objectForKey:@"week"]; weaInfo.wind = [weatherInfoDic objectForKey:@"wind1"]; weaInfo.weather = [weatherInfoDic objectForKey:@"weather1"]; weaInfo.tip = [weatherInfoDic objectForKey:@"index"]; returnweaInfo; } 3 在请求网络的地方请求 - (void)getNetData{ [[WTNetWorkingManager shareWTNetWorkingManager]getWeatherCallBack:^(idobj) { weather* weaInfo =obj; self.weatherInfo =weaInfo; [self giveValue]; }]; } - (void)giveValue{ self.city.text =self.weatherInfo.city; self.date.text =self.weatherInfo.date; self.week.text =self.weatherInfo.week; self.wind.text =self.weatherInfo.wind; self.weather.text =self.weatherInfo.weather; self.tips.text =self.weatherInfo.tip; self.tips.userInteractionEnabled=NO; } 我封装的类可以去我github拿：https://github.com/wangdachui
