iOS 自己封装的网络请求，json解析的类

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。

#pragma mark ios请求方式
//ios自带的get请求方式
-(void)getddByUrlPath:(NSString *)path andParams:(NSString *)params andCallBack:(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(), ^{

id jsonData = [NSJSONSerialization JSONObjectWithData:data options:0 error: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*)params andCallBack:(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:params options: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);
id  jsonData = [NSJSONSerialization JSONObjectWithData:data options:0 error:Nil];
if ([jsonData  isKindOfClass:[NSArray  class]]) {
NSDictionary*  dic = jsonData[0];

callback(dic);

}else{
callback(jsonData);
}
});

}];
//开始请求
[task resume];

}
}

#pragma mark 第三方请求方式
//第三方的get请求方式
-(void)getByApiName:(NSString *)apiName andParams:(id)params andCallBack:(CallBack)callback{
[self.manager GET:apiName parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

callback(responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

callback(nil);

}];

}
//第三方的post请求方式
-(void)postByApiName:(NSString *)apiName andParams:(id)params andCallBack:(CallBack)callback{

[self.manager POST:apiName parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

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)params  andImagesArray:(NSArray*)images andBack:(CallBack)callback{
[self.manager POST:apiName parameters:params constructingBodyWithBlock:^(id formData) {

for (int i = 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, id responseObject) {

callback(responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
callback(nil);

}];
}

-(void)postImageByApiName:(NSString *)apiName  andImageName:(NSString*)imageName  andParams:(id)params  andImage:(UIImage*)image andBack:(CallBack)callback{
NSData*  imageData = UIImageJPEGRepresentation(image, 0.8);

[self.manager POST:apiName parameters:params constructingBodyWithBlock:^(id formData) {
[formData appendPartWithFileData:imageData name:imageName fileName:[NSString stringWithFormat:@"image.jpg"] mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
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:^(id obj) {

//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"];

return weaInfo;
}

3 在请求网络的地方请求

- (void)getNetData{

[[WTNetWorkingManager shareWTNetWorkingManager]getWeatherCallBack:^(id obj) {

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;
}
