After investigation, The following behavior is confirmed :
The `HttpClient` GET method itself works correctly. However, signer may need
special encoding handling for query parameters.
### Example
For a GET request like:
```
GET /v1/.../view-details?viewNamePattern=view%
```
**Current Flow:**
```
Original parameters: view%
|
| <- First encoding
↓
Client signature: view%25
|
| <- Second encoding
↓
HTTP request: view%2525
↓
Server receives: view%2525
|
| <- (Default behavior of web container, such as Tomcat)
↓
Server decodes: view%25
↓
Server signature: view%25
↓
✅ Verification matches
```
### Summary
1. **Query parameters undergo double encoding:**
- First encoding in `RESTAuthParameter` constructor: `view%` → `view%25`
- Second encoding by `URIBuilder.addParameter()`: `view%25` → `view%2525`
2. **Aware of this encoding behavior**
- When implementing server-side signature verification, must be aware of
this encoding behavior and handle it according to specific authentication
protocol requirements
