常常, 我们用通过这个方案调用API。

    NSString* urlString = [NSString stringWithFormat:@"http://api.douban.com/v2/movie/search?q=%@", content];
    
    NSURL *url = [NSURL URLWithString:urlString];
    testRequest = [ASIHTTPRequest requestWithURL:url];
    [testRequest setDelegate:self];
    [testRequest startAsynchronous];
