在iOS的网络请求中,第三方框架 AFNetworking 对网络请求的封装程度已经很高了,但相对而言,对于有些许强迫症的我,还是试了一下再次封装.
网络请求成功时,responseObject为服务器返回的数据,successMsg为成功信息;
网络请求失败时,num为根据服务器返回的错误码,errorMsg为错误信息;
#import <Foundation/Foundation.h>
//请求成功回调block
typedef void (^requestNewSuccessBlock) (NSDictionary *responseObject, NSString *successMsg);
//请求失败回调block
typedef void (^requestNewFailureBlock) (int num, NSString *errorMsg);
//请求方式
typedef enum {
NewGET = 100,
NewPOST,
NewDelete,
NewPut,
} HTTPNewMethod;
@interface CustomerNewSession : AFHTTPSessionManager
+ (instancetype)sharedSessionManager;
//新接口
- (void)requestWithNewMethod:(HTTPNewMethod)method
withPath:(NSString *)path
withParams:(NSDictionary *)params
withSuccessBlock:(requestNewSuccessBlock)success
withFailureBlock:(requestNewFailureBlock)failure;
@end
#import "CustomerNewSession.h"
@implementation CustomerNewSession
+ (instancetype)sharedSessionManager {
static CustomerNewSession *manager = nil;
static dispatch_once_t pred;
dispatch_once(&pred, ^{
manager = [[self alloc] initWithBaseURL:nil];
});
return manager;
}
- (instancetype)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (self) {
// 请求超时设定
self.requestSerializer.timeoutInterval = networkTime;
// 请求头设定
[self.requestSerializer setValue:@"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[self.requestSerializer setValue:@"2" forHTTPHeaderField:@"interface_version"];
// 安全策略 - 无条件信任
self.securityPolicy = [[AFSecurityPolicy alloc] init];
[self.securityPolicy setAllowInvalidCertificates:YES];
[self.securityPolicy setValidatesDomainName:NO];

return self;
