AFNetworking第三方库的封装

对请求参数、请求头和AFNetworking本身进行了封装

• ViewController显示用法

    //需要打开网络请求开关，并导入AFNetworking第三方库
    //具体封装内容全在BSGHTTPManager里面，使用封装的时候直接复制过去即可使用
    
    BSGHTTPManager * manager = [BSGHTTPManager manager];
    
    //本请求不需要参数，以下展示参数写法：
    manager.phone = @"示例";
    
    
    [manager BSGPost:@"http://api.k780.com:88/?app=life.time&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=json" success:^(NSURLSessionDataTask *task, id responseDictionary) {
        NSLog(@"responseDictionary:%@",responseDictionary);
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"error:%@",error);
    }];
    

• BSGHTTPManager展示封装过程

1. BSGHTTPManager.h

#import <Foundation/Foundation.h>

@interface BSGHTTPManager : NSObject

//参数

/** 手机号码，即账号*/
@property(nonatomic, copy) NSString * phone;
/** 密码*/
@property(nonatomic, copy) NSString * password;



//创建管理者
+(instancetype)manager;


//成功返回Block
typedef void(^successBlock)(NSURLSessionDataTask * task, id responseDictionary);
//失败返回Block
typedef void(^failureBlock)(NSURLSessionDataTask * task, NSError * error);

//POST方法
-(void)BSGPost:(NSString *)URLString success:(successBlock)success failure:(failureBlock)failture;

//GET方法
-(void)BSGGet:(NSString *)URLString success:(successBlock)success failure:(failureBlock)failture;

//Block写在内部的例子
-(void)BSGTest:(NSString *)aString andBlock:(void(^)(NSString *resultString))block;



@end

2. BSGHTTPManager.m

#import "BSGHTTPManager.h"
#import <AFHTTPSessionManager.h>

@implementation BSGHTTPManager



+(instancetype)manager{
    return [[[self class] alloc] init];
}




//AFNetworking的POST方法
-(void)BSGPost:(NSString *)URLString success:(successBlock)success failure:(failureBlock)failture
{
    
    AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];
    
    //内部设置请求头
    [manager.requestSerializer setValue:@"2" forHTTPHeaderField:@"type"];
    [manager.requestSerializer setValue:@"1" forHTTPHeaderField:@"application"];
    
    
    NSMutableDictionary * paramDic = [NSMutableDictionary dictionary];
    paramDic = [self BSGGetParam];
    
    
    [manager POST:URLString parameters:paramDic progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        //回传Block数据
        success(task,responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        //回传Block数据
        failture(task,error);
    }];
    
    
}



//AFNetworking的GET方法
-(void)BSGGet:(NSString *)URLString success:(successBlock)success failure:(failureBlock)failture
{
    
    AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];
    
    //内部设置请求头
    [manager.requestSerializer setValue:@"2" forHTTPHeaderField:@"type"];
    [manager.requestSerializer setValue:@"1" forHTTPHeaderField:@"application"];
    

    NSMutableDictionary * paramDic = [NSMutableDictionary dictionary];
    paramDic = [self BSGGetParam];
    
    [manager GET:URLString parameters:paramDic progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        //回传Block数据
        success(task,responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        //回传Block数据
        failture(task,error);
    }];
    
    
    
}


//获取网络请求参数。请求时直接将参数传入
-(NSMutableDictionary *)BSGGetParam{
    NSMutableDictionary * tmpDic = [NSMutableDictionary dictionary];
    
    tmpDic = [self BSGAddObjectFrom:tmpDic value:self.phone          key:@"phone"];
    tmpDic = [self BSGAddObjectFrom:tmpDic value:self.password       key:@"password"];
    
    //    tmpDic = [self BSGAddObjectFrom:tmpDic value:self.<#value#> key:@"<#content#>"];
    
    return tmpDic;
}

/* 判断加入请求参数的数据是否为空，如果为空则不添加，避免添加空元素报错*/
-(NSMutableDictionary *)BSGAddObjectFrom:(NSMutableDictionary *)anDictionary value:(NSString*)anValue key:(NSString *)anKey{
    if (anValue) {
        [anDictionary setObject:anValue forKey:anKey];
    }
    return anDictionary;
}



//测试示例
-(void)BSGTest:(NSString *)aString andBlock:(void (^)(NSString *))block
{
    NSString * resultStr = [aString stringByAppendingString:@"123"];
    
    block(resultStr);
}
