如何获取iPhone中正在下载的zip文件名
目前使用 SSZipArchive 方法下载 zip 文件并解压缩到 Documents 目录文件夹中。我正在从 URL 下载 zip 文件名,但目前不知道该文件名,因为每次有更新时它都会更改。收到数据后如何检索文件名?
- (void)viewDidLoad {
fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
directoryPath = [paths objectAtIndex:0];
filePath = [NSString stringWithFormat:@"%@/ZipFiles.zip", directoryPath];
NSURL *url=[NSURL URLWithString:@"http://www.abc.com/test/test.cfc?id=123"];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
[fileManager createFileAtPath:filePath contents:urlData attributes:nil];
[SSZipArchive unzipFileAtPath:filePath toDestination:directoryPath];
NSString *responseString = [[NSString alloc] initWithData:urlData encoding:NSASCIIStringEncoding];
///***Answer to my own question for future needs****//
NSString *fileName = [response suggestedFilename];
}
Currently using SSZipArchive method to download the zip file and unzip at Documents directory folder. I am downloading the zip file name from URL and currently unaware of the file name because it changes each time there are any updates. How can I retrieve the file name when I receive my data ?
- (void)viewDidLoad {
fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
directoryPath = [paths objectAtIndex:0];
filePath = [NSString stringWithFormat:@"%@/ZipFiles.zip", directoryPath];
NSURL *url=[NSURL URLWithString:@"http://www.abc.com/test/test.cfc?id=123"];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
[fileManager createFileAtPath:filePath contents:urlData attributes:nil];
[SSZipArchive unzipFileAtPath:filePath toDestination:directoryPath];
NSString *responseString = [[NSString alloc] initWithData:urlData encoding:NSASCIIStringEncoding];
///***Answer to my own question for future needs****//
NSString *fileName = [response suggestedFilename];
}

NSURLResponse
有一个方法- (NSString *)suggestedFilename
它将尝试按此顺序获取文件名。内容处置标头将是最好的解决方案,因此请确保服务器设置它。
NSURLResponse
has a method- (NSString *)suggestedFilename
which will attempt to get the file name in this order.The content disposition header would be the best solution so make sure that the server sets it.
