PHP_header location 使用注意事项

帅比萌擦擦* 提交于 2019-11-30 09:13:08
header("Location:login.php")应该注意的几个问题 header("Location:")作为php的转向语句。其实在使用中,他有几点需要注意的地方。 1、要求header前没有任何输出 但是很多时候在header前我们已经输出了好多东西了,此时如果再次header的话,显然是出错的,在这里我们启用了一个ob的概念,ob的意思是在服务器端先存储有关输出,等待适当的时机再输出,而不是像现在这样运行一句,输出一句,发现header语句就只能报错了。 具体的语句有: ob_start(); ob_end_clean();ob_flush();......... 2、在header("Location:")后要及时exit 否则他是会继续执行的,虽然在浏览器端你看不到相应的数据出现,但是如果你进行抓包分析的话,你就会看到下面的语句也是在执行的。而且被输送到了浏览器客户端,只不过是没有被浏览器执行为html而已(浏览器执行了header进行了转向操作)。 所以,标准的使用方法是: ob_start(); ........ if ( something ){ ob_end_clean(); header("Location: yourlocation"); exit; else{ .......... ob_flush(); //可省略 要想在header前有输出的话

Android 百度地图开发之MyLocationOverlay,PopupOverlay的使用

这一篇文章主要讲解的是百度地图的定位功能,然后还有MyLocationOverlay和PopupOverlay两个地图覆盖物的使用,Overlay是“图层”或“覆盖物”的意思,MyLocationOverlay从名字上面理解就是我的位置图层,他能够实现在地图上显示当前位置的图标以及指南针,MyLocationOverlay只负责显示我的位置,位置数据请使用百度定位SDK获取,将获取的位置数据放在一个LocationData结构中并用该结构设置MyLcationOverlay的数据源,即可创建MyLocationOverlay,PopupOverlay就是弹出窗口图层了,跟PopupWindow类似的东西,下面会介绍他们的使用方法 定位我们使用的是百度 Android 定位SDKv4.0,我们先了解下定位原理和定位精度 定位原理 使用百度Android定位SDK必须注册GPS和网络使用权限。定位SDK采用GPS、基站、Wi-Fi信号进行定位。当应用程序向定位SDK发起定位请求时,定位SDK会根据应用的定位因素(GPS、基站、Wi-Fi信号)的实际情况(如是否开启GPS、是否连接网络、是否有信号等)来生成相应定位依据进行定位。 用户可以设置满足自身需求的定位依据: 若用户设置GPS优先,则优先使用GPS进行定位,如果GPS定位未打开或者没有可用位置信息,且网络连接正常

Rewrite和location 区别

ewrite 和 location 区别: rewrite 是在同一域名内更改资源获取的路径 Location 是对路径 做控制访问或反向代理,可以使用 proxy_pass 到其他主机 很多情况下 rewrite 会写在 location 里, 他们的执行顺序: 执行 server 块的 rewrite 指令 执行 location 匹配 执行选定的 location 中的 rewrite 指令 来源: https://www.cnblogs.com/liu1584712/p/11573071.html

E.g. something like: MyWebClient.AllowAutoRedirect = false; (of HttpWebRequest) 回答1: You could write a custom web client and enable this functionality: public class WebClientEx : WebClient { protected override WebRequest GetWebRequest(Uri address) { var request = (HttpWebRequest)base.GetWebRequest(address); request.AllowAutoRedirect = false; return request; } } and then: using (var client = new WebClientEx()) { Console.WriteLine(client.DownloadString(

How to get the current location of iPhone through code?

只谈情不闲聊 提交于 2019-11-30 07:41:45
How do you get the current location of iPhone through code? I need to track the location using GPS. You're looking for the "CoreLocation" API. Here's a tutorial Roger There is (as always for core functionality) comprehensive documentation on the developer site and you may find this example useful; The key points to remember are; 1) Once you start receiving location updates, they arrive asynchronously and you need to respond to them as and when they come in. Check the accuracy and timestamps to decide if you want to use the location or not. 2) Don't forget to stop receiving updates as soon as
