# Getting start with API application development
|
||
|
|
Go is very good for developing API applications which I think is the biggest strength compare to other dynamic languages. Beego provides powerful and quick setup tool for developing API applications, which gives you more focus on business logic.
|
||
|
|
|
||
|
|
|
||
|
|
## Quick setup
|
||
|
|
bee can setup a API application very quick by executing commands under any `$GOPATH/src`.
|
||
|
|
|
||
|
|
`bee api beeapi`
|
||
|
|
|
||
|
|
## Application directory structure
|
||
|
|
|
||
|
|
```
|
||
|
|
├── conf
|
||
|
|
│ └── app.conf
|
||
|
|
├── controllers
|
||
|
|
│ └── default.go
|
||
|
|
├── models
|
||
|
|
│ └── object.go
|
||
|
|
└── main.go
|
||
|
|
```
|
||
|
|
|
||
|
|
## Source code explanation
|
||
|
|
|
||
|
|
- app.conf has following configuration options for your API applications:
|
||
|
|
|
||
|
|
- autorender = false // Disable auto-render since API applications don't need.
|
||
|
|
- copyrequestbody = true // RESTFul applications sends raw body instead of form, so we need to read body specifically.
|
||
|
|
|
||
|
|
- main.go is for registering routers of RESTFul.
|
||
|
|
|
||
|
|
beego.RESTRouter("/object", &controllers.ObejctController{})
|
||
|
|
|
||
|
|
Match rules as follows:
|
||
|
|
|
||
|
|
<table>
|
||
|
|
<tr>
|
||
|
|
<th>URL</th> <th>HTTP Verb</th> <th>Functionality</th>
|
||
|
|
</tr>
|
||
|
|
<tr>
|
||
|
|
<td>/object</td> <td>POST</td> <td>Creating Objects</td>
|
||
|
|
</tr>
|
||
|
|
<tr>
|
||
|
|
<td>/object/objectId</td> <td>GET</td> <td>Retrieving Objects</td>
|
||
|
|
</tr>
|
||
|
|
<tr>
|
||
|
|
<td>/object/objectId</td> <td>PUT</td> <td>Updating Objects</td>
|
||
|
|
</tr>
|
||
|
|
<tr>
|
||
|
|
<td>/object</td> <td>GET</td> <td>Queries</td>
|
||
|
|
</tr>
|
||
|
|
<tr>
|
||
|
|
<td>/object/objectId</td> <td>DELETE</td> <td>Deleting Objects</td>
|
||
|
|
</tr>
|
||
|
|
</table>
|
||
|
|
|
||
|
|
- ObejctController implemented corresponding methods:
|
||
|
|
|
||
|
|
type ObejctController struct {
|
||
|
|
beego.Controller
|
||
|
|
}
|
||
|
|
|
||
|
|
func (this *ObejctController) Post(){
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
func (this *ObejctController) Get(){
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
func (this *ObejctController) Put(){
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
func (this *ObejctController) Delete(){
|
||
|
|
|
||
|
|
}
|
||
|
|
|
||
|
|
- models implemented corresponding object operation for adding, deleting, updating and getting.
|
||
|
|
|
||
|
|
## Test
|
||
|
|
|
||
|
|
- Add a new object:
|
||
|
|
|
||
|
|
curl -X POST -d '{"Score":1337,"PlayerName":"Sean Plott"}' http://127.0.0.1:8080/object
|
||
|
|
|
||
|
|
Returns a corresponding objectID:astaxie1373349756660423900
|
||
|
|
|
||
|
|
- Query a object:
|
||
|
|
|
||
|
|
`curl -X GET http://127.0.0.1:8080/object/astaxie1373349756660423900`
|
||
|
|
|
||
|
|
- Query all objects:
|
||
|
|
|
||
|
|
`curl -X GET http://127.0.0.1:8080/object`
|
||
|
|
|
||
|
|
- Update a object:
|
||
|
|
|
||
|
|
`curl -X PUT -d '{"Score":10000}'http://127.0.0.1:8080/object/astaxie1373349756660423900`
|
||
|
|
|
||
|
|
- Delete a object:
|
||
|
|
|
||
|
|
`curl -X DELETE http://127.0.0.1:8080/object/astaxie1373349756660423900`
