In my code, I am trying to send the id and dept fields in a DELETE HTTP request and then retrieve them inside the deleteData() function. However, I am encountering an issue where the values for id and dept are coming up as null within the deleteData() function.
$http['delete']('webapi/Data/delete?' + cdata.id + "&&" + cdata.lineUp)
@DELETE()
@Path("/delete")
public String deleteData(@QueryParam("id") String id, @QueryParam("dept") String dept){
When using the HTTP Delete method, you cannot pass data as an argument. </p>
<p><strong>This Approach Will Not Work</strong> </p>
<p>In this scenario, passing an object would look like this:</p>
<pre><code>var cdata = {
id: 2,
lineUp: [...]
};
// This won't work
$http.delete('webapi/Data/delete, cdata)
.then(function(response) {
console.log(response);
})
.then(function(error) {
console.log(error);
});
For a truly RESTful approach, you should only need to provide the id to the HTTP Delete method.
Embrace RESTFul Design
var cdata = {
id: 2,
lineUp: [...]
};
// Using RESTful design
$http.delete('webapi/Data/delete/' + cdata.id)
.then(function(response) {
console.log(response);
})
.then(function(error) {
console.log(error);
});
If necessary, you can utilize the HTTP Post method as a workaround.
Here's a Workaround
var cdata = {
id: 2,
lineUp: [...]
};
// This is a workaround
$http.post('webapi/Data/delete, cdata)
.then(function(response) {
console.log(response);
})
.then(function(error) {
console.log(error);
});
