This is what I have:
private void doPut(String url, String encodedPostData) {
try {
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST,
url+"?_method=PUT");
builder.setHeader("Content-Type", FormPanel.ENCODING_URLENCODED);
DOM.setStyleAttribute(RootPanel.getBodyElement(), "cursor", "progress");
builder.sendRequest(encodedPostData, this);
} catch (RequestException e) {
GWT.log( "error", e);
e.printStackTrace();
DOM.setStyleAttribute(RootPanel.getBodyElement(), "cursor", "");
}
}
public void doDelete(String url, RESTRequestCallback restCallback) {
this.restCallback = restCallback;
try {
RequestBuilder builder = new RequestBuilder(RequestBuilder.POST,
url+"?_method=DELETE");
builder.setHeader("Content-Type", FormPanel.ENCODING_URLENCODED);
/*
* The foo,bar here is so we don't send an empty POST request. There
* is a bug in firebug and/or nginx where it responds with a 411
* when an empty post is sent.
*
* I haven't experimented with moving the _method=DELETE into the params
* or only adding this if the encodedParams array is null. There are
* probably better ways to fix this, but for now, this works.
*/
DOM.setStyleAttribute(RootPanel.getBodyElement(), "cursor", "progress");
builder.sendRequest(encodeParams(new String[] { "foo", "bar"} ), this);
} catch (RequestException e) {
GWT.log("error", e);
e.printStackTrace();
DOM.setStyleAttribute(RootPanel.getBodyElement(), "cursor", "");
}
}
