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;
}
