网络请求封装 使用NSURLSession

How to use

//第一种  会自动将model与json匹配
self.mobileNumber = [MobileNumber new];
[self.mobileNumber checkMobileNumber:@"15210011578"];

//第二种 返回json字典
NSURLSessionDataTask *task =  [YAHRequestManager
getNetworkDataWithURL:@"http://apis.baidu.com/apistore/mobilenumber/mobilenumber" 
           method:@"GET" 
    completeBlock:^(NSDictionary * _Nullable jsonDic, NSError * _Nullable error) {
    NSLog(@"%@", jsonDic);
} parameters:@{@"phone": @"15210011578"} 
     headers:@{@"apikey": @"123456789"}];

一般项目使用的是第一种。 例如服务端返回的这种JSON

{
"errNum": 0,
"retMsg": "success",
"retData": {
    "phone": "15210011578",
    "prefix": "1521001",
    "supplier": "移动 ",
    "province": "北京 ",
    "city": "北京 ",
    "suit": "152卡"
    }
}

需要新建三个类来处理

.h
@interface MobileData : YAHActiveObject

@property (nonatomic, copy) NSString *phone;
@property (nonatomic, copy) NSString *prefix;
@property (nonatomic, copy) NSString *supplier;
@property (nonatomic, copy) NSString *province;
@property (nonatomic, copy) NSString *city;
@property (nonatomic, copy) NSString *suit;

@end

@interface MobileRespone : YAHDataResponseInfo

@property (nonatomic, strong) MobileData *retData;

@end

@interface MobileNumber : YAHModelRequest

- (void)checkMobileNumber:(NSString *)number;

@end

.m
#import "MobileNumber.h"

@implementation MobileData
@end

@implementation MobileRespone
@end

@implementation MobileNumber

- (instancetype)init
{
    self = [super initWithURL:@"mobilenumber/mobilenumber" resultClass:[MobileRespone class]];
    if (self) {
        self.method = @"GET";
        [self setValue:@"" forHTTPHeaderField:@"apikey"];  //apikey http://apistore.baidu.com/ 上注册
    }
    return self;
}

- (void)checkMobileNumber:(NSString *)number {

    [self addParamWithkey:@"phone" value:number];
    [self getNetworkData:^{
    NSLog(@"%@", self.result);
    } failure:^(NSString * _Nullable errorMsg) {
    NSLog(@"%@", errorMsg);
    }];
}

@end

MobileNumber 网络请求
MobileRespone 返回数据检验 （是否有效）
MobileData  需要用到的返回数据  该类中的属性名要与jso中的key要一一对应，若想不对应需要重
写changeJSONPropertyKey该函数,若属性是某个类需要重写convertClassString函数
+ (NSDictionary *)changeJSONPropertyKey {
    return @{@"mykey":@"jsonkey"};
}
+ (NSDictionary *)convertClassString {
    return @{@"property":@"class"};
}
