iOS 自己封装的网络请求，json解析的类

Posted 2022-11-30 ShineYangGod

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;
