如何在AFNetworking 2.0中设置请求超时和缓存策略？
如何在AFNetworking 2.0中设置请求超时和缓存策略？
提问于 2013-11-13 12:36:01
我遵循给定的示例代码
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);
}];为了更改超时和缓存策略，我“黑掉”了库并创建了
- (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;
}有干净的方法吗？

我有点懒于分类或子类。可以直接访问管理器的请求序列化程序：
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval = INTERNET_TIMEOUT;
manager.requestSerializer.cachePolicy = NSURLRequestReloadIgnoringLocalAndRemoteCacheData;Stack Overflow用户

最好是创建一个子类。
(您也可以以相同的方式添加缓存策略)
TimeoutAFHTTPRequestSerializer.h
#import "AFURLRequestSerialization.h"
@interface TimeoutAFHTTPRequestSerializer : AFHTTPRequestSerializer
@property (nonatomic, assign) NSTimeInterval timeout;
- (id)initWithTimeout:(NSTimeInterval)timeout;
@endTimeoutAFHTTPRequestSerializer.m
#import "TimeoutAFHTTPRequestSerializer.h"
@implementation TimeoutAFHTTPRequestSerializer
- (id)initWithTimeout:(NSTimeInterval)timeout {
self = [super init];
if (self) {
self.timeout = timeout;
}
return self;
}
- (NSMutableURLRequest *)requestWithMethod:(NSString *)method
URLString:(NSString *)URLString
parameters:(NSDictionary *)parameters
error:(NSError *__autoreleasing *)error
{
NSMutableURLRequest *request = [super requestWithMethod:method URLString:URLString parameters:parameters error:error];
if (self.timeout > 0) {
[request setTimeoutInterval:self.timeout];
}
return request;
}
@end使用
self.requestOperationManager.requestSerializer = [[TimeoutAFHTTPRequestSerializer alloc] initWithTimeout:30];Stack Overflow用户

您还可以创建一个类别AFHTTPRequestOperationManager+timeout来添加此方法，而不必对AFHTTPRequestOperationManager进行子类分类。
