使用AFNetworking 2.0时,我遇到了一些关于流媒体请求的挑战.

我想将大量文件(~50MB)上传到服务器,并且请求必须要流式传输.(否则app会因内存压力而崩溃)

我已尝试过各种方法在AFNetworking 2.0中做到这一点而没有任何成功.这就是我目前正在做的事情:

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:baseServiceUrl parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    int imageIndex = 0;
    for (NSURL *tempFileUrl in tempFilesUrlList) {
        NSString* fileName = [NSString stringWithFormat:@"image%d", imageIndex];
        NSError *appendError = nil;
        [formData appendPartWithFileURL:tempFileUrl name:fileName error:&appendError];
        imageIndex++;
    }
} error:&error];

AFHTTPRequestOperation *requestOperation = nil;
requestOperation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
    DLog(@"Uploading files completed: %@\n %@", operation, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    DLog(@"Error: %@", error);
}];

[requestOperation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, …

我想在目标C中编写一个url提取函数.输入文本可以是任何内容,可能包含也可能不包含html锚标记.

考虑一下:

NSString* input1 = @"This is cool site <a   href="https://abc.com/coolstuff"> Have fun exploring </a>";
NSString* input2 = @"This is cool site <a target="_blank" href="https://abc.com/coolstuff"> Must visit </a>";
NSString* input3 = @"This is cool site <a href="https://abc.com/coolstuff" target="_blank" > Try now </a>";

我想修改字符串为 "This is cool site https://abc.com/coolstuff

忽略锚标记之间的所有文本.并且需要考虑其他属性,例如锚标记中的_target

我可以做点什么

static NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"<a\shref=\"(.*?)\">.*?</a>" options:NSRegularExpressionCaseInsensitive error:nil];;
NSString* modifiedString = [regex stringByReplacingMatchesInString:inputString options:0 range:NSMakeRange(0, [inputString length]) withTemplate:@"$1"];

使用input1工作正常但在其他情况下失败.

谢谢
