Alamofire Swift获取HTML源码 [英] Alamofire Swift get html source

问题描述

我只想从一个简单的网站中检索html源。

I just want to retrieve the html source from a simple website.

@IBAction func scan_func(sender: AnyObject) {
        Alamofire.request(.GET, "http://www.example.com")
            .response { request, response, data, error in
                print(request)
                print(response)
                print(data)
        }
    }

我已经成功地在info.plist中添加了应用程序传输安全设置和允许任意加载以加载http内容。

I already have successfully added "App Transport Security Settings" and "Allow Arbitrary Loads" to info.plist to load http content.

运行该代码时，我只会得到这样的输出：
XCODE-十六进制输出
我希望您可以帮助我。

When I run that code I only get an output like this: XCODE - hexadecimal output I hope you can help me.

亲切的问候

推荐答案

您正在打印取出数据的原始字节。我猜您正在寻找一种打印相应字符串表示形式的方法。
例如，您可以使用Alamofire提供的闭包来完成此操作：

You are printing out the raw bytes of the data. I'm guessing you are looking for a way to print out the corresponding string representation. You could for instance do this with Alamofire's provided closure:

Alamofire.request(.GET, "http://www.example.com")
    .responseString { response in
        print("Response String: \(response.result.value)")
}

（查看文档此处）

或者，您也可以自己转换字符串：

Alternatively, you could convert the string yourself:

Alamofire.request(.GET, "http://www.example.com")
    .response { request, response, data, error in
        print(String(data: data, encoding: String.Encoding.utf8))
}
