api-config.yaml
```
name: pixiu
description: pixiu sample
resources:
- path: 'xxx'
...
methods:
- httpVerb: POST
...
integrationRequest:
...
url: "x.x.x.1:20005, x.x.x.2:20005"
```
**What would you like to be added**:
problem:
- it works well if url is 'x.x.x.1:20005,x.x.x.2:20005'
- it does not work well if url is 'x.x.x.1:20005, x.x.x.2:20005', since it
will get a url named ' x.x.x.2:20005' , and expected url is 'x.x.x.2:20005'
which does not have a space;
code comes from /pixiu/pkg/filter/http/loadbalancer/loadbalancer.go
```
func (f *Filter) Decode(c *contexthttp.HttpContext) filter.FilterStatus {
allInstances :=
strings.Split(c.GetAPI().IntegrationRequest.HTTPBackendConfig.URL, ",")
idx := rand.Int31n(int32(len(allInstances)))
c.Api.IntegrationRequest.HTTPBackendConfig.URL = allInstances[idx]
return filter.Continue
}
```
it could be enhanced as follows:
```
c.Api.IntegrationRequest.HTTPBackendConfig.URL =
strings.TrimSpace(allInstances[idx])
```
**Why is this needed**:
easy to use
