Question

我有来自cancelByProducingResumeData的resumeData的字典：如下所示，我想知道如何使用NSURLSessionResumeCurrentRequest为HTMLHeaderField添加值。

我想知道如何将NSURLSessionResumeCurrentRequest的NSData转换为NSURLRequest。

我尝试使用以下代码更改我的请求，非常成功！ ;）

- (NSData *)regenerateResumeData:(NSData *)originData
{
    NSString *error;
    NSPropertyListFormat format;
    NSMutableDictionary* plist = [NSMutableDictionary dictionaryWithDictionary:[NSPropertyListSerialization propertyListFromData:originData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error]];

    NSData *currentRequest = [plist objectForKey:@"NSURLSessionResumeCurrentRequest"]; 
    NSURLRequest *request = [(NSURLRequest *)[NSKeyedUnarchiver unarchiveObjectWithData:currentRequest] copy];
    NSMutableURLRequest *mutableRequest = [request mutableCopy];
    [mutableRequest addValue:[plist objectForKey:@"NSURLSessionResumeEntityTag"] forHTTPHeaderField:@"If-Match"];
    [mutableRequest addValue:[NSString stringWithFormat:@"bytes=%@-", [plist objectForKey:@"NSURLSessionResumeBytesReceived"]] forHTTPHeaderField:@"Range"];
    request = [mutableRequest copy];

    NSData *archivedData = [NSKeyedArchiver archivedDataWithRootObject:request];

    [plist removeObjectForKey:@"NSURLSessionResumeCurrentRequest"];
    [plist setValue:archivedData forKey:@"NSURLSessionResumeCurrentRequest"];

    return [NSPropertyListSerialization dataFromPropertyList:plist format:NSPropertyListBinaryFormat_v1_0 errorDescription:&error];
}

如何从RESTUR的NSURLSessionResumeCurrentRequest添加来自HTMLHeaderField的值？
