下載PPTX文件我的文件路徑URL下面如何從URL
http://ccidahra.com/wp-content/uploads/2016/03/sample.ppt
給出當我在瀏覽器,它瀏覽器中打開給選項來下載文件。這意味着URL是正確的,也下載文件已打開,因此文件也正確。但是當我嘗試在iOS中使用代碼做同樣的事情時。我收到錯誤。我寫下面的代碼來下載文件。
NSString *fullURL = @"http://ccidahra.com/wp-content/uploads/2016/03/sample.ppt";
NSString *encodedURL = [fullURL stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLHostAllowedCharacterSet]];
NSURL *url = [NSURL URLWithString:encodedURL];
NSLog(@"fullURL %@",fullURL);
NSURLSession *sessions = [NSURLSession sharedSession];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url];
NSURLSessionDataTask *dataTask = [sessions dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (!error) {
NSString *docPath = [[AppDelegate documentsDirectory] stringByAppendingString:@"/sample.ppt"];
if ([[NSFileManager defaultManager] fileExistsAtPath:docPath]){
[[NSFileManager defaultManager ]removeItemAtPath:docPath error:nil];
}
if ([[NSFileManager defaultManager] createFileAtPath:docPath contents:data attributes:nil]) {
NSLog(@"file created ar %@",docPath);
}
else{
NSLog(@"file can not created ar %@",docPath);
}
}else
{
NSLog(@"Error %@",error);
dispatch_async(dispatch_get_main_queue(), ^{
[MBProgressHUD hideHUDForView:self.view animated:YES];
});
[AlertView showAlertWithTitle:@"Error" withMessage:@"Service error! Please connect to the internet" inViewController:self];
}
}];
[dataTask resume];
我得到以下錯誤,當下載文件。
Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSUnderlyingError=0x608000253fb0 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}, NSErrorFailingURLStringKey=http%3A%2F%2Fccidahra.com%2Fwp-content%2Fuploads%2F2016%2F03%2Fsample.ppt, NSErrorFailingURLKey=http%3A%2F%2Fccidahra.com%2Fwp-content%2Fuploads%2F2016%2F03%2Fsample.ppt, NSLocalizedDescription=unsupported URL}
請幫我解決這個問題。我想在UIWebview中打開ppt,pptx,doc文件。
爲什麼百分號編碼,你的網址是什麼? – rmaddy
URL可能有效,但服務器也可以拒絕您的請求。當您在瀏覽器中訪問URL時,除了下載文件外,還有更多內容(例如,呈現指示您登錄的用戶的Cookie) –
