Question

知道为什么sendSynchronousRequest不起作用，并且返回nil。错误和响应也是零。

let url = NSURL(fileURLWithPath: "http://google.com")!
let ur = NSMutableURLRequest(URL: url)
let response: AutoreleasingUnsafeMutablePointer<NSURLResponse?> = nil
let errorPtr = NSErrorPointer()
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
    let data = NSURLConnection.sendSynchronousRequest(ur, returningResponse: response, error: errorPtr)
    if errorPtr != nil {
        var error: NSError = errorPtr.memory!
    }
})

我尝试了异步方式：

var oq = NSOperationQueue()
NSURLConnection.sendAsynchronousRequest(ur, queue: oq, completionHandler: {response, data, error in

    let ii = 7
})

我在这里收到错误：

（lldb）po错误错误域= NSURLErrorDomain代码= -1100＆＃34;在此服务器上找不到请求的URL。＆＃34; UserInfo = 0x1567f9d0 {NSErrorFailingURLStringKey = file：/// http：/google.com，NSErrorFailingURLKey = file：/// http：/ google.com,NSLocalizedDescription =在此服务器上找不到请求的URL。，NSUnderlyingError = 0x15691880＆＃ 34;在此服务器上找不到请求的URL。＆＃34;}

奇怪的谷歌不可用？

您正在使用fileURLWithPath并返回该网址文件：///private/var/folders/xs/6k9v2g217155wr9vgb3xrg_80000gn/T/com.apple.dt.Xcode.pg/containers/com.apple.dt.playground.stub.iOS_Simulator.MyPlayground-F81D60A5-6797-4BEB-8AB9 -2D156E2B6771 / HTTP：/google.com

您需要的是let url = NSURL(string: "http://google.com")!并返回网址：
http://google.com

NSURLConnection sendSynchronousRequest不起作用
