iOS 自己封裝的網路請求，json解析的類
基本上所有的APP都會涉及網路這塊，不管是用AFNetWorking還是自己寫的http請求，整個網路框架的搭建很重要。
樓主封裝的網路請求類，包括自己寫的http請求和AFNetWorking的請求，程式碼簡單，主要是框架搭建。簡單來說，就是一個請求類，一個解析類，還有若干資料類。
以下程式碼以公開的天氣查詢api為例：
1.網路請求類
我把常用的網路請求方法都封裝好了，你只需要寫自己的介面，傳遞apiName，params等引數就可以。
pragma mark ios請求方式
//ios自帶的get請求方式
-(void)getddByUrlPath:(NSString )path andParams:(NSString
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); } }); }]; //開始請求 [task resume];
}
//ios自帶的post請求方式
-(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); } }); }]; //開始請求 [task resume]; }
}
pragma mark 第三方請求方式
//第三方的get請求方式
-(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請求方式
-(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上傳圖片請求方式
-(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);
}];
}
以天氣查詢為例，自己寫個介面，選擇請求方式：
-(void)getWeatherCallBack:(CallBack)callback{
//選擇需要的請求方式，我們採用非第三方的get請求，具體情況選擇不同的請求方式，都是非同步請求
[self getddByUrlPath:@"http://m.weather.com.cn/data/101190101.html" andParams:nil andCallBack:^(id obj) {
//json解析
weather* weatherInfo = [WTParseWeather parseWeatherByWeatherDic:obj];
//返回解析後的資料
callback(weatherInfo);
}];
}
2 解析類，這個不同的資料要不同的解析類，自己寫，這個是天氣的例子：
+(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 在請求網路的地方請求
(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;
}
