iOS开发对AFNetworking3.0的二次封装

①封装

创建一个新的类,我暂且命名为HttpRequest

.h文件

#import <Foundation/Foundation.h>
@class AFNetworking;
@interface HttpRequest : NSObject

+ (HttpRequest *)sharedInstance;

- (void)GET:(NSString *)URLString dict:(id)dict succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure;

- (void)POST:(NSString *)URLString dict:(id)dict succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure;

@end

.m文件

#import "HttpRequest.h"
#import "AFNetworking.h"

@implementation HttpRequest
/**
 *  创建网络请求类的单例
 */
static HttpRequest *httpRequest = nil;
+ (HttpRequest *)sharedInstance
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        if (httpRequest == nil) {
            httpRequest = [[self alloc] init];
        }
    });
    return httpRequest;
}
+(instancetype)allocWithZone:(struct _NSZone *)zone
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        if (httpRequest == nil) {
            httpRequest = [super allocWithZone:zone];
        }
    });
    return httpRequest;
}
- (instancetype)copyWithZone:(NSZone *)zone
{
    return httpRequest;
}
/**
 *  封装AFN的GET请求
 *
 *  @param URLString 网络请求地址
 *  @param dict      参数(可以是字典或者nil)
 *  @param succeed   成功后执行success block
 *  @param failure   失败后执行failure block
 */
- (void)GET:(NSString *)URLString dict:(id)dict succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure
{
    //创建网络请求管理对象
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    //申明返回的结果是json类型
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    //申明请求的数据是json类型
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    //如果报接受类型不一致请替换一致text/html或别的
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html", nil];
    //发送网络请求(请求方式为GET)
    [manager GET:URLString parameters:dict progress:^(NSProgress * _Nonnull downloadProgress) {
        
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        succeed(responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        failure(error);
    }];
}
/**
 *  封装AFN的POST请求
 *
 *  @param URLString 网络请求地址
 *  @param dict      参数(可以是字典或者nil)
 *  @param succeed   成功后执行success block
 *  @param failure   失败后执行failure block
 */
- (void)POST:(NSString *)URLString dict:(id)dict succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure
{
    //创建网络请求管理对象
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    //申明返回的结果是json类型
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    //申明请求的数据是json类型
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    //如果报接受类型不一致请替换一致text/html或别的
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html", nil];
    //发送网络请求(请求方式为POST)
    [manager POST:URLString parameters:dict progress:^(NSProgress * _Nonnull uploadProgress) {
        
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        succeed(responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        failure(error);
    }];
}

@end

②使用

调用时代码很少,很方便使用(也可以把调用的代码写成代码片段,提高效率)

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:<#(nonnull id), ...#>, nil];
HttpRequest *httpRequest = [HttpRequest sharedInstance];
[httpRequest GET:<#(NSString *)#> dict:dict succeed:^(id data) {
    NSLog(@"%@", data);
    
} failure:^(NSError *error) {
    NSLog(@"%@", error);
}];

如果不需要传参数,就不用创建dict了,get请求那里直接写nil就行.

post跟get一样,除了把get改成post,其余地方都不用改动
