网络请求封装_html/css_WEB-ITnose

新建NetTool文件继承于NSObject在里面进行网络请求的封装

NetTool.h

• 定义两个枚举类型 然后重命名两个block

    //get&post用枚举来展示数据类型  typedef NS_ENUM(NSUInteger, WSSResponseStyle) {  WSSJSON,  WSSDATA,  WSSXML,  };  //POST里body类型的枚举  typedef NS_ENUM(NSUInteger, WSSRequestStyle) {  WSSBodyJSON,  WSSBodyString,  };  //重定义成功和失败的block  typedef void(^blockofSuccess)(id result);  typedef void(^blockofFailure)(NSError *error);  @interface WSSNetTool : NSObject

• 定义方法,分别是简单GET请求,简单POST请求,带加载小菊花的GET请求

    //对AFN再进行GET封装,方便自己使用  + (void)GetNetByURL:(NSString *)urlString                 body:(id)body//GET的body体              headers:(NSDictionary *)headers//请求头             response:(WSSResponseStyle)response//枚举类型              success:(blockofSuccess)success//成功之后返回这个block              failure:(blockofFailure)failure;//想要返回的数据类型(枚举类型的JSON/DATA/XML)                                              //失败之后返回这个block,可以在里面打印error了解请求失败的原因  //对AFN再进行POST封装,方便自己使用  + (void)PostNetByURL:(NSString *)urlString                 body:(id)body//POST的body体            bodyStyle:(WSSRequestStyle)bodyStyle//body类型(枚举值)              headers:(NSDictionary *)headers//请求头             response:(WSSResponseStyle)response              success:(blockofSuccess)success              failure:(blockofFailure)failure;//想要返回的数据类型(枚举类型的JSON/DATA/XML)  //有小菊花的get封装  + (void)GetNet2ByURL:(NSString *)urlString                 body:(id)body//GET的body体              headers:(NSDictionary *)headers//请求头             response:(WSSResponseStyle)response              success:(blockofSuccess)success              failure:(blockofFailure)failure             selfView:(UIView *)selfView;

• 简单GET请求的实现

• 简单POST请求的实现

• 带有加载小菊花的GET请求的实现ps:这个方法的参数多了一个self.view是为了实现加载小菊花的添加以及加载结束小菊花的remove

+ (void)GetNet2ByURL:(NSString *)urlString body:(id)body headers:(NSDictionary *)headers response:(WSSResponseStyle)response success:(blockofSuccess)success failure:(blockofFailure)failure selfView:(UIView *)selfView{    //1.获取网络管理者    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];    //2.请求头的设置    if (headers)//如果有请求头    {        for (NSString *key in headers.allKeys)        {            [manager.requestSerializer setValue:headers[key] forHTTPHeaderField:key];        }    }    //3.设置返回数据的类型    switch (response)    {        case WSSJSON:            manager.responseSerializer = [AFJSONResponseSerializer serializer];            break;        case WSSXML:            manager.responseSerializer = [AFXMLParserResponseSerializer serializer];            break;        case WSSDATA:            manager.responseSerializer = [AFHTTPResponseSerializer serializer];            break;        default:            break;    }    //4.设置响应数据的类型    [manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", @"application/javascript",@"image/jpeg", @"text/vnd.wap.wml", nil]];    //5.若有汉语进行UTF8转码(这个方法是iOS9之后的方法)    urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];    //添加菊花    MBProgressHUD *mbView = [MBProgressHUD showHUDAddedTo:selfView animated:YES];    mbView.detailsLabelText = @"请耐心等待,网络加载中";    //6.发送请求    [manager GET:urlString parameters:body progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {        //成功block回调        success(responseObject);        //取消菊花        [mbView hide:YES];    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {        NSLog(@"失败原因:%@", error);        //取消菊花        [mbView hide:YES];        //失败block回调        failure(error);    }];}
