## Routing with special characters
|
||
|
|
|
||
|
|
Routing with special characters can lead to unexpected results. For example, consider a controller with the following action method:
|
||
|
|
|
||
|
|
```csharp
|
||
|
|
[HttpGet("{id?}/name")]
|
||
|
|
public async Task<ActionResult<string>> GetName(string id)
|
||
|
|
{
|
||
|
|
var todoItem = await _context.TodoItems.FindAsync(id);
|
||
|
|
|
||
|
|
if (todoItem == null || todoItem.Name == null)
|
||
|
|
{
|
||
|
|
return NotFound();
|
||
|
|
}
|
||
|
|
|
||
|
|
return todoItem.Name;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
When `string id` contains the following encoded values, unexpected results might occur:
|
||
|
|
|
||
|
|
| ASCII | Encoded |
|
||
|
|
| ----| ---------- |
|
||
|
|
| `/` | `%2F` |
|
||
|
|
| ` ` | `+` |
|
||
|
|
|
||
|
|
Route parameters are not always URL decoded. This problem may be addressed in the future. For more information, see [this GitHub issue](https://github.com/dotnet/aspnetcore/issues/11544);
