salesforce pagereference 和接收url上传递的参数

http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_system_pagereference.htm salesforce 官方介绍 pagereference

pagereference

fullURL可以是一个完整的链接地址。也可以是一个相对路径。

也可以通过url中传递链接参数。string fullURL = 'http://www.baidu.com/s?wd=a';a 可以当做一个参数传递进去。

代码如下：

PageReference pageRef = new PageReference('fullURL');

这个方法中 PageReference acctPage = new ApexPages.StandardController(account).view(); 默认调转到account默认的视图中（在pagelayout中自定义按钮中会用到这个方法）。 setRedirect(Boolean) Sets the value of the PageReference object's redirect attribute. If set to true, a redirect is performed through
a client side redirect.意思是说，设置成true，直接就从客户端跳转了。

public PageReference save() {
// Add the account to the database.
insert account;
// Send the user to the detail page for the new account.
PageReference acctPage = new ApexPages.StandardController(account).view();
acctPage.setRedirect(true);
return acctPage;
}
