## Documentation for Servers
150+
151+
Parameterized Servers are supported. Define a server in the API for each endpoint with arbitrary numbers of variables:
152+
153+
```
154+
servers:
155+
- url: http://{server}:{port}/{basePath}
156+
description: Description of the Server
157+
variables:
158+
server:
159+
enum:
160+
- 'petstore'
161+
- 'qa-petstore'
162+
- 'dev-petstore'
163+
default: 'petstore'
164+
port:
165+
enum:
166+
- '3000'
167+
- '1000'
168+
default: '3000'
169+
basePath:
170+
default: v1
171+
```
172+
To change the default variable, use this function in each Api:
173+
```
174+
int setDefaultServerValue(int serverIndex,const QString &operation, const QString &variable,const QString &val);
175+
```
176+
The parameter "serverIndex" will choose a server from the server list for each endpoint. There is always at least one server with index 0. The Paramter "operation" should be the desired endpoint operationid.
177+
Variable is the name of the variable you wish to change and the value is the new default Value.
178+
The function will return -1 when the variable does not exists, -2 if value is not defined in the variable enum and -3 if the operation is not found.
179+
180+
If your endpoint has multiple server objects in the servers array, you can set the server that will be used with this function:
181+
```
182+
void setServerIndex(const QString &operation, int serverIndex);
183+
```
184+
Parameter "operation" should be your operationid. "serverIndex" is the index you want to set as your default server. The function will check if there is a server with your index.
185+
Here is an example of multiple servers in the servers array. The first server will have index 0 and the second will have index 1.
186+
```
187+
servers:
188+
- url: http://{server}:8080/
189+
description: Description of the Server
190+
variables:
191+
server:
192+
enum:
193+
- 'petstore'
194+
- 'qa-petstore'
195+
- 'dev-petstore'
196+
default: 'petstore'
197+
- url: https://localhost:8080/v1
198+
```
