## 跳转和错误
|
||||
我们在做Web开发的时候，经常会遇到页面调整和错误处理，beego这这方面也进行了考虑，通过`Redirect`方法来进行跳转：
|
||||
##Redirect and error
|
||||
You can use following to redirect:
|
||||
|
||||
func (this *AddController) Get() {
|
||||
this.Redirect("/", 302)
|
||||
}
|

||||
@todo Error processing need to be improved.
|
||||
|
||||
## response处理
|
||||
response可能会有集中情况：
|
||||
##Handle response
|
||||
There are some situations that you may have in response:
|
||||
|
||||
1. 模板输出
|
||||
1. Output template
|
||||
|
||||
模板输出上面模板介绍里面已经介绍，beego会在执行完相应的Controller里面的对应的Method之后输出到模板。
|
||||
I've already talked about template above, Beego outputs template after corresponding method executed.
|
||||
|
||||
2. 跳转
|
||||
2. Redirect
|
||||
|
||||
上一节介绍的跳转就是我们经常用到的页面之间的跳转
|
||||
You can use this.Redirect("/", 302) to redirect page.
|
||||
|
||||
3. 字符串输出
|
||||
3. Output string
|
||||
|
||||
有些时候我们只是想输出相应的一个字符串，那么我们可以通过如下的代码实现
|
||||
Sometimes we just need to print string on the screen:
|
||||
|
||||
this.Ctx.WriteString("ok")
|
||||
|
||||
## Sessions
|
||||
beego内置了session模块，目前session模块支持的后端引擎包括memory、file、mysql、redis四中，用户也可以根据相应的interface实现自己的引擎。
|
||||
Beego has a built-in session module and supports four engines, including memory, file, MySQL and redis. You can implement your own engine based on the interface.
|
||||
|
||||
beego中使用session相当方便，只要在main入口函数中设置如下：
|
||||
It's easy to use session in Beego, use following code in your main() function:
|
||||
|
||||
beego.SessionOn = true
|
||||
|
||||
或者通过配置文件配置如下：
|
||||
Or use configuration file:
|
||||
|
||||
sessionon = true
|
||||
|
||||
通过这种方式就可以开启session，如何使用session，请看下面的例子：
|
||||
The following example shows you how to use session in Beego:
|
||||
|
||||
func (this *MainController) Get() {
|
||||
v := this.GetSession("asta")
|
||||
@ -516,68 +516,67 @@ beego中使用session相当方便，只要在main入口函数中设置如下：
|
||||
this.TplNames = "index.tpl"
|
||||
}
|
||||
|
||||
上面的例子中我们知道session有几个方便的方法：
|
||||
We can see that there are few convenient methods:
|
||||
|
||||
- SetSession(name string, value interface{})
|
||||
- GetSession(name string) interface{}
|
||||
- DelSession(name string)
|
||||
|
||||
session操作主要有设置session、获取session、删除session
|
||||
There are three kinds of operation for session: set, get, and delete.
|
||||
|
||||
当然你要可以通过下面的方式自己控制相应的逻辑这些逻辑：
|
||||
Of course you can use following code to customized session logic:
|
||||
|
||||
sess:=this.StartSession()
|
||||
defer sess.SessionRelease()
|
||||
|
||||
sess对象具有如下方法：
|
||||
The sess object has following methods:
|
||||
|
||||
* sess.Set()
|
||||
* sess.Get()
|
||||
* sess.Delete()
|
||||
* sess.SessionID()
|
||||
|
||||
但是我还是建议大家采用SetSession、GetSession、DelSession三个方法来操作，避免自己在操作的过程中资源没释放的问题。
|
||||
However, I recommend you to use SetSession、GetSession、DelSession these three operations in order to prevent resource leak.
|
||||
|
||||
关于Session模块使用中的一些参数设置：
|
||||
There are some arguments you can use in session module:
|
||||
|
||||
- SessionOn
|
||||
|
||||
设置是否开启Session，默认是false，配置文件对应的参数名：sessionon
|
||||
Whether enable session or not, default is false, corresponding arguments in configuration file: sessionon.
|
||||
|
||||
- SessionProvider
|
||||
|
||||
设置Session的引擎，默认是memory，目前支持还有file、mysql、redis等，配置文件对应的参数名：sessionprovider
|
||||
Setting session engine, default is memory, other options are file, MySQL and redis, corresponding arguments in configuration file: sessionprovider.
|
||||
|
||||
- SessionName
|
||||
|
||||
设置cookies的名字，Session默认是保存在用户的浏览器cookies里面的，默认名是beegosessionID，配置文件对应的参数名是：sessionname
|
||||
Setting name of cookies, it saves in users' browser with name beegosessionID, corresponding arguments in configuration file: sessionname.
|
||||
|
||||
- SessionGCMaxLifetime
|
||||
|
||||
设置Session过期的时间，默认值是3600秒，配置文件对应的参数：sessiongcmaxlifetime
|
||||
Setting session expired time, default is 3600 seconds, corresponding arguments in configuration: sessiongcmaxlifetime
|
||||
|
||||
- SessionSavePath
|
||||
|
||||
设置对应file、mysql、redis引擎的保存路径或者链接地址，默认值是空，配置文件对应的参数：sessionsavepath
|
||||
Setting save path or link address of corresponding file, MySQL and redis engines, default is empty, corresponding arguments in configuration file: sessionsavepath
|
||||
|
||||
|
||||
当SessionProvider为file时，SessionSavePath是只保存文件的目录，如下所示：
|
||||
When the SessionProvider is file, SessionSavePath saves file path:
|
||||
|
||||
beego.SessionProvider = "file"
|
||||
beego.SessionSavePath = "./tmp"
|
||||
|
||||
当SessionProvider为mysql时，SessionSavePath是链接地址，采用[go-sql-driver](https://github.com/go-sql-driver/mysql)，如下所示：
|
||||
When the SessionProvider is mysql, SessionSavePath is link address, it uses driver [go-sql-driver](https://github.com/go-sql-driver/mysql):
|
||||
|
||||
beego.SessionProvider = "mysql"
|
||||
beego.SessionSavePath = "username:password@protocol(address)/dbname?param=value"
|
||||
|
||||
当SessionProvider为redis时，SessionSavePath是redis的链接地址，采用了[redigo](https://github.com/garyburd/redigo)，如下所示：
|
||||
When the SessionProvider is redis, SessionSavePath is link address of redis, it uses driver [redigo](https://github.com/garyburd/redigo):

beego.SessionSavePath = "127.0.0.1:6379"

## Cache设置
|
||||
beego内置了一个cache模块，实现了类似memcache的功能，缓存数据在内存中，主要的使用方法如下：
|
||||
## Cache
|
||||

上面这个例子演示了如何使用beego的Cache模块，主要是通过`beego.NewBeeCache`初始化一个对象，然后设置过期时间，开启过期检测，在业务逻辑中就可以通过如下的接口进行增删改的操作：
|
||||
To use cache, you need to initialize a `beego.NewBeeCache` object and set expired time, and enable expired check. Then you can use following methods to achieve other operations:
|
||||
|
||||
- Get(name string) interface{}
|
||||
- Put(name string, value interface{}, expired int) error
|
||||
- Delete(name string) (ok bool, err error)
|
||||
- IsExist(name string) bool
|
||||
|
||||
## 安全的Map
|
||||
我们知道在Go语言里面map是非线程安全的，详细的[atomic_maps](http://golang.org/doc/faq#atomic_maps)。但是我们在平常的业务中经常需要用到线程安全的map，特别是在goroutine的情况下，所以beego内置了一个简单的线程安全的map：
|
||||
##Safe map
|
||||
We know that map is not thread safe in Go, if you don't know it, this article may be helpful for you: [atomic_maps](http://golang.org/doc/faq#atomic_maps). However, we need a kind of thread safe map in practice, especially when we are using goroutines. Therefore, Beego provides a simple built-in thread safe map implementation.

|

This map has following interfaces:
|
||||

||||
- Get(k interface{}) interface{}
|
||||
- Set(k interface{}, v interface{}) bool
|
||||
- Check(k interface{}) bool
|
||||
- Delete(k interface{})
|
||||

||||
## 日志处理
|
||||
beego默认有一个初始化的BeeLogger对象输出内容到stdout中，你可以通过如下的方式设置自己的输出：
|
||||
##Log
|
||||
Beego has a default BeeLogger object that outputs log into stdout, and you can use your own logger as well:
|
||||
|
||||
beego.SetLogger(*log.Logger)
|
||||
|
||||
只要你的输出符合`*log.Logger`就可以，例如输出到文件：

|
||||
Your project may have a lot of log outputs, but you don't want to output everything after your application is running on the internet, for example, you want to ignore Trace, Debug and Info level log outputs, you can use following setting:

||||
beego.SetLevel(beego.LevelWarning)

这样的话就不会输出小于这个level的日志，日志的排序如下：

Then Beego will not output log that has lower level of LevelWarning. Here is the list of all log levels, order from lower to higher:
|
||||

||||
LevelTrace、LevelDebug、LevelInfo、LevelWarning、 LevelError、LevelCritical

## 第三方应用集成
|
||||
beego支持第三方应用的集成，用户可以自定义`http.Handler`,用户可以通过如下方式进行注册路由：

||||

||||

## 部署编译应用
|
||||
Go语言的应用最后编译之后是一个二进制文件，你只需要copy这个应用到服务器上，运行起来就行。beego由于带有几个静态文件、配置文件、模板文件三个目录，所以用户部署的时候需要同时copy这三个目录到相应的部署应用之下，下面以我实际的应用部署为例：
|
||||
##Deployment
|
||||
Go compiles program to binary file, you only need to copy this binary to your server and run it. Because Beego uses MVC model, so you may have folders for static files, configuration files and template files, so you have to copy those files as well. Here is a real example for deployment.
