网络请求封装_html/css_WEB-ITnose-HTML Tutorial-php.cn

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

+(void)GetNetByURL:(NSString *)urlString body:(id)body headers:(NSDictionary *)headers response:(WSSResponseStyle)response success:(blockofSuccess)success failure:(blockofFailure)failure{ //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]]; //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); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"失败原因:%@", error); //失败block回调 failure(error); }];}

简单POST请求的实现

+ (void)PostNetByURL:(NSString *)urlString body:(id)body bodyStyle:(WSSRequestStyle)bodyStyle headers:(NSDictionary *)headers response:(WSSResponseStyle)response success:(blockofSuccess)success failure:(blockofFailure)failure{ //1.获取网络管理者 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; //2.设置body数据类型 switch (bodyStyle) { case WSSBodyJSON: manager.requestSerializer = [AFJSONRequestSerializer serializer]; break; case WSSBodyString: [manager.requestSerializer setQueryStringSerializationWithBlock:^NSString * _Nonnull(NSURLRequest * _Nonnull request, id _Nonnull parameters, NSError * _Nullable * _Nullable error) { return parameters; }]; break; default: break; } //3.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]; } } //4.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; } //5.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]]; //设置可请求https manager.securityPolicy.allowInvalidCertificates = YES; //6.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]]; //7.发送请求 [manager POST:urlString parameters:body progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { //成功block回调 success(responseObject); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"失败原因:%@", error); //失败block回调 failure(error); }];}

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); }];}
