Question

我尝试从我的服务器下载一个文件，这是代码，在我的控制台上我看到了xml文件，但我无法保存。问题出在哪里？

- (IBAction)grabURL:(id)sender{

    NSURL *url = [NSURL URLWithString:@"http://www.endurodoc.net/photo/data.xml"];
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    [request startSynchronous];

    NSError *error = [request error];
    if (!error) {
        NSString *response = [request responseString];
        NSLog(@"%@",response);

    }
    else{
        NSLog(@"Errore");
    }    

    //[request setDownloadDestinationPath:@"/Users/kikko/Desktop/data.xml"];

    // SAVED PDF PATH
    // Get the Document directory
    NSString *documentDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    // Add your filename to the directory to create your saved pdf location
    NSString *pdfLocation = [documentDirectory stringByAppendingPathComponent:@"data.xml"];

    // TEMPORARY PDF PATH
    // Get the Caches directory
    NSString *cachesDirectory = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
    // Add your filename to the directory to create your temp pdf location
    NSString *tempPdfLocation = [cachesDirectory stringByAppendingPathComponent:@"data.xml"];

    // Tell ASIHTTPRequest where to save things:
    [request setTemporaryFileDownloadPath:tempPdfLocation];     
    [request setDownloadDestinationPath:pdfLocation]; 

}

Answer 1

你需要把：

[request setTemporaryFileDownloadPath:tempPdfLocation];     
[request setDownloadDestinationPath:pdfLocation];

之前：

[request startSynchronous];

ASIHTTPRequest在请求发出时保存文件，因此如果在请求发生后设置了这些属性，则不会发生任何事情。
