In a new Web API project with :
GET
method
// GET api/values/5 public string Get(int id) { return "value"; }
DELETE
method
// DELETE api/values/5 public void Delete(int id) { var client = new MongoClient("mongodb://localhost:27017"); var server = client.GetServer(); var db = server.GetDatabase("Test"); var collection = db.GetCollection<Entity>("Entities"); var deleteEntity = Query<Entity>.EQ(e => e.Id, id); collection.Remove(deleteEntity); }
They have a similar URL: api/values/5
.
When I want to call the Delete
method, it executes the Get
method. What do I do?
The URL is the same but you invoke this URL programaticaly with a "DELETE" 'http method' rather than "GET". If you are just navigating to the URL in your browser, the browser will only do a GET. How you programmatically do a DELETE (or POST or PUT) will depend on what library you are using to invoke the service but they all tend to have some kind of parameter or property called 'method' for setting this.
Take a look at the HttpDelete
attribute:
https://msdn.microsoft.com/en-us/library/system.web.mvc.httpdeleteattribute(v=vs.118).aspx
You need to decorate your methods like this so that MVC knows how to handle the incoming request:
[HttpGet]
public string Get(int id)
{
...
}
[HttpDelete]
public void Delete(int id)
{
...
}
If you're submitting to the delete method via an HTML form, bear in mind they only support the POST and GET methods, so you'll need to submit the DELETE via JavaScript:
Use...
Get: /controller/123456
Delete: /controller/id/123456
The config piece below solved my problem:
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<!--This will enable all Web API verbose-->
