AFNetworking之缓存篇
苦苦看了我两天，最近后台为了减轻压力，要我做缓存，我说好吧......
借鉴了别人的说法找到一张图可以看明白好多：
这个是我比较战成一种方案。
好了直接上代码了
首先我们要有自己缓存的类 说以就自己用读写方式简单写了一个类
+ (void)cacheForData:(NSData *)data fileName:(NSString *)fileName
{
NSString *path = [kCachePath stringByAppendingPathComponent:[YBMD5 md5:fileName]];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[data writeToFile:path atomically:YES];
});
}
+ (NSData *)getCacheFileName:(NSString *)fileName
{
NSString *path = [kCachePath stringByAppendingPathComponent:[YBMD5 md5:fileName]];
return [[NSData alloc] initWithContentsOfFile:path];
}
+ (NSUInteger)getAFNSize
{
NSUInteger size = 0;
NSFileManager *fm = [NSFileManager defaultManager];
NSDirectoryEnumerator *fileEnumerator = [fm enumeratorAtPath:kCachePath];
for (NSString *fileName in fileEnumerator) {
NSString *filePath = [kCachePath stringByAppendingPathComponent:fileName];
NSDictionary *attrs = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:nil];
size += [attrs fileSize];
}
return size;
}
这些大家都有自己的方式 。
然后开始在我们的AF中写一些东西 就可以了
-(AFHTTPSessionManager *)manager{
static AFHTTPSessionManager *rmanager = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
rmanager = [AFHTTPSessionManager manager];
rmanager.responseSerializer = [AFJSONResponseSerializer serializer];
rmanager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/plain",@"image/jpg",@"application/x-javascript",@"keep-alive", nil];
// 设置超时时间
[rmanager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
rmanager.requestSerializer.timeoutInterval = 60.f;
[rmanager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
});
return rmanager;
}
-(void)requsetWithPath:(NSString *)path withParams:(NSDictionary *)params withCacheType:(YBCacheType)cacheType withRequestType:(NetworkRequestType)type withResult:(ZmzBlock)resultBlock{
if (!self.isConnected) {
NSLog(@"没有网络,建议在手机设置中打开网络");
// return;
}
switch (type) {
case NetworkGetType:
{
YBCache *cache = [self getCache:cacheType url:path params:params withResult:resultBlock];
NSString *fileName = cache.fileName;
if (cache.result) return;
[self.manager GET:path parameters:params progress:^(NSProgress * _Nonnull downloadProgress) {
YBLog(@"---------%lld", downloadProgress.totalUnitCount);
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (resultBlock) {
//缓存数据
NSData *data = [NSJSONSerialization dataWithJSONObject:responseObject options:NSJSONWritingPrettyPrinted error:nil];
[YBCacheTool cacheForData:data fileName:fileName];
[self handleRequestResultWithDataTask:task responseObject:responseObject error:nil resultBlock:resultBlock];
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handleRequestResultWithDataTask:task responseObject:nil error:error resultBlock:resultBlock];
}];
}
break;
case NetworkPostType:
{
NSString *cutPath = [NSString stringWithFormat:@"%@%@",MAIN_URLL,path];
//缓存数据的文件名 data
YBCache *cache = [self getCache:cacheType url:cutPath params:params withResult:resultBlock];
NSString *fileName = cache.fileName;
if (cache.result) return;
[self.manager POST:cutPath parameters:params progress:^(NSProgress * _Nonnull uploadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (resultBlock) {
//缓存数据
NSData *data = [NSJSONSerialization dataWithJSONObject:responseObject options:NSJSONWritingPrettyPrinted error:nil];
[YBCacheTool cacheForData:data fileName:fileName];
[self handleRequestResultWithDataTask:task responseObject:responseObject error:nil resultBlock:resultBlock];
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
[self handleRequestResultWithDataTask:task responseObject:nil error:error resultBlock:resultBlock];
}];
}
break;
default:
break;
}
}
这样大致的步骤就搞定了，可以根据自己的项目需求来定。
这只是成功的第一步 之后又整了半天 整理到了git上去
