网络请求

自己封装的一个网络请求 以类方法的形式调用 基于AFNetworking
在.h中声明

+ (void)PostData:(NSDictionary*)para url:(NSString*)url success:(void (^)(id responseDic))success fail:(void (^)(NSError *error))fail;
+ (void)GetData:(NSDictionary*)para url:(NSString*)url success:(void (^)(id responseDic))success fail:(void (^)(NSError *error))fail;

在.m中实现

+ (void)PostData:(NSDictionary*)para url:(NSString*)url success:(void (^)(id responseDic))success fail:(void (^)(NSError *error))fail{
    
    AFHTTPSessionManager *Postmanager = [AFHTTPSessionManager manager];
    // 设置返回格式
    Postmanager.responseSerializer = [AFHTTPResponseSerializer serializer];
    Postmanager.requestSerializer  = [AFJSONRequestSerializer serializer];
    //超时时间
    [Postmanager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
    [Postmanager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
    Postmanager.requestSerializer.timeoutInterval = 12;
    //设置token
    [Postmanager.requestSerializer setValue:[TokenStore sharedData].token forHTTPHeaderField:@"token"];
    //post请求
    [Postmanager POST:url parameters:para progress:^(NSProgress * _Nonnull uploadProgress) {
        
    
            } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                
            
            NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];

                success(dict);
        
            } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                NSLog(@"error = %@",error.localizedDescription);
                
                fail(error);
                
            }];
   
    }

+ (void)GetData:(NSDictionary*)para url:(NSString*)url success:(void (^)(id responseDic))success fail:(void (^)(NSError *error))fail{
    
    AFHTTPSessionManager *Getmanager = [AFHTTPSessionManager manager];;
    // 设置返回格式
    Getmanager.responseSerializer = [AFHTTPResponseSerializer serializer];
    Getmanager.requestSerializer  = [AFHTTPRequestSerializer serializer];
    //设置token
    [Getmanager.requestSerializer setValue:[TokenStore sharedData].token forHTTPHeaderField:@"token"];

    //设置超时时间
    [Getmanager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
    [Getmanager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
    Getmanager.requestSerializer.timeoutInterval = 12;
    //get请求
    [Getmanager GET:url parameters:para progress:^(NSProgress * _Nonnull uploadProgress) {
        
        
        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            
        NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
        
        success(dict);
        
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"error = %@",error.localizedDescription);
        
        fail(error);
        
        }];
    
    }

引入头文件调用类方法即可使用,例如:

 [NetManage PostData:nil url:self.url success:^(id responseDic) {

        //数据解析        

    } fail:^(NSError *error) {

        NSLog(@"失败");

    }];
