如何在AFNetworking 2.0中设置请求超时和缓存策略？ [英] How do I set a request timeout and cache policy in AFNetworking 2.0?

问题描述

我正在关注给定的示例代码

I'm following the given example code

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

要更改超时和缓存策略，我已经入侵了库并创建了

To change the timeout and cache policy I 'hacked' the library and created

- (AFHTTPRequestOperation *)GET:(NSString *)URLString
                     parameters:(NSDictionary *)parameters
                          timeoutInterval:(NSTimeInterval)timeoutInterval
                    cachePolicy:(NSURLRequestCachePolicy)cachePolicy
                        success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
                        failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure
{
    NSMutableURLRequest *request = [self.requestSerializer requestWithMethod:@"GET" URLString:[[NSURL URLWithString:URLString relativeToURL:self.baseURL] absoluteString] parameters:parameters];
    [request setTimeoutInterval:timeoutInterval];
    [request setCachePolicy:cachePolicy];
    AFHTTPRequestOperation *operation = [self HTTPRequestOperationWithRequest:request success:success failure:failure];
    [self.operationQueue addOperation:operation];

    return operation;
}

有没有干净的方法呢？

推荐答案

我有点懒于分类或子类。您可以直接访问经理的请求序列化程序：

I'm a bit lazy to categorize or subclass. You can access the manager's request serializer directly:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval = INTERNET_TIMEOUT;
manager.requestSerializer.cachePolicy = NSURLRequestReloadIgnoringLocalAndRemoteCacheData;
