主要步骤
创建的AFNetworkingManager类继承自NSObject类
请求类型用枚举定义
/** 请求类型的枚举 */
typedef NS_ENUM(NSUInteger, SkyHttpRequestType)
{
/** get请求 */
SkyHttpRequestTypeGet = 0,
/** post请求 */
SkyHttpRequestTypePost
};
- 用block回调请求结果
/**
http通讯成功的block
@param responseObject 返回的数据
*/
typedef void (^SkyHTTPRequestSuccessBlock)(id responseObject);
/**
http通讯失败后的block
@param error 返回的错误信息
*/
typedef void (^SkyHTTPRequestFailedBlock)(NSError *error);
- 在.m文件中导入#import "AFHTTPSessionManager.h"，并获取AFHTTPSessionManager类単例
static AFHTTPSessionManager *aManager;
+ (AFHTTPSessionManager *)sharedAFManager
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
aManager = [AFHTTPSessionManager manager];
//以下三项manager的属性根据需要进行配置
aManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html",@"text/xml",@"text/json",@"text/plain",@"text/JavaScript",@"application/json",@"image/jpeg",@"image/png",@"application/octet-stream",nil];
aManager.responseSerializer = [AFHTTPResponseSerializer serializer];
// 设置超时时间
aManager.requestSerializer.timeoutInterval = kAFNetworkingTimeoutInterval;
});
return aManager;
}
- failure返回的"error.code == -999"为取消请求队列
if (error.code !=-999) {
if (failureBlock)
{
failureBlock(error);
}
}
else{
NSLog(@"取消队列了");
}
- 以上
