我有从服务器下载图像阵列的问题,如果我有100个图像在服务器上意味着我应该下载所有图像使用“AFImageRequestOperation”,而下载过程中一些图像下载成功,但许多图像被下载失败的,因为从服务器“超时”的错误,我用大尺寸图像(3.mb)面临超时问题,如何在AFImageRequestOperation中设置超时值
我使用follwing方式来下载图片:
NSURL *url = [NSURL URLWithString:kBaseURLString];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
[httpClient setAuthorizationHeaderWithUsername:[[NSUserDefaults standardUserDefaults] stringForKey:kUserDefaultKeyUsername]
password:[[NSUserDefaults standardUserDefaults] stringForKey:kUserDefaultKeyPassword]];
for(int i = 0; i < [self.downloadImageList count]; i++) {
NSString *filename = [[NSString alloc] initWithString:[self.downloadImageList objectAtIndex:i]];
NSMutableURLRequest *urlRequest = [httpClient multipartFormRequestWithMethod:@"POST"
path:@"/xxx/yyyyyyyyyy/getImage"
parameters:nil
constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFormData:[filename dataUsingEncoding:NSUTF8StringEncoding]
name:kFormNameFile];
}];
AFImageRequestOperation *requestOperation = [[AFImageRequestOperation alloc] initWithRequest:urlRequest];
[requestOperation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
[self updateSyncClientUIDelegateProgress:(totalBytesRead/totalBytesExpectedToRead) andLabel:@"Downloading Images"];
}];
[requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
if([[urlRequest URL] isEqual:[[operation request] URL]]) {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
UIImage *image = responseObject;
NSLog(@"Downloading image %@",image);
[UIImagePNGRepresentation(image) writeToFile:[syncedImagesPath stringByAppendingPathComponent:filename] atomically:YES];
});
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if([[operation response] statusCode] == 404) {
return;
}
NSLog(@"failure BLOCK %@",error);
NSLog(@"failure error code %ld",(long)[error code]);
if([error code] != NSURLErrorCannotDecodeContentData) {
[self cancelSyncFromFailure];
}
}];
请帮我在下载大内存时修复此超时问题
仍然面临着同样的问题的解决,实际上即时从服务器获取错误错误:错误域= NSURLErrorDomain代码= -1001“请求超时。” UserInfo = 0x12830130 {NSErrorFailingURLStringKey = http://xxxxx.com/yyyy/httpbroker/getImage,NSErrorFailingURLKey = http://xxxxx.com/yyyyy/httpbroker/getImage,NSLocalizedDescription =请求超时,NSUnderlyingError = 0xe351d60“请求超时。“}失败错误代码-1001 – karthick
