我正在尝试在iOS应用中查看我的PHP结果。代码如下：
func get()
{
//let url = NSURL(string: "http://www.w3schools.com/js/customers_mysql.php")
let url = NSURL(string: "http://www.helpmewastetime.com/service.php")
let data = NSData(contentsOf: url! as URL)
values = try! JSONSerialization.jsonObject(with: data! as Data, options: JSONSerialization.ReadingOptions.allowFragments) as! NSArray
var array = [""]
array = (values.value(forKey: "Name") as? [String])!
lb_Value.text = array[0]
}
该代码在W3Schools链接中工作正常，但是当我使用链接时它会崩溃（托管在Go Daddy上）如果您从Web浏览器打开链接，我们将获得预期的结果。
这是收到的错误：

任何帮助都将不胜感激
正如埃里克·艾亚（Eric Aya）在评论中提到的那样。问题在于，您的PHP服务将JSON数据吐出到HTML页面中。
当我查看您的页面源时，我会得到以下内容：
<html>
[{"ID":"1","Name":"Peter"},{"ID":"2","Name":"James"}]
</html>
W3Schools URL的页面源只是JSON。在您的PHP服务中，将数据输出在JSON中，您应该很好。
