Re: Sending HTML as JSON with RequestBuilder

This way I'm sending html with JSON without problems:

public final class HtmlJSONWrapper extends JavaScriptObject {

   public static native HtmlJSONWrapper create(String jsonStr) /*-{

return JSON.parse(jsonStr);

            }-*/;

   

   public static native HtmlJSONWrapper create() /*-{

    return {}

   }-*/;

public final native String getContent() /*-{

return this.htmlContent;

}-*/;

public final native void setContent(String value) /*-{

this.htmlContent = value;

}-*/;

   public String toJSONString() {

    return new JSONObject(this).toString();

   }

}

...

HtmlJSONWrapper htmlWrapper = HtmlJSONWrapper.create();

htmlWrapper.setContent(richTextArea.getHTML());

...

        RequestBuilder builder = new RequestBuilder(RequestBuilder.POST, url);

        builder.setHeader("Content-Type", "application/json");

        try {

            Request response = builder.sendRequest(htmlWrapper.toJSONString(), requestCallback);

        } catch (RequestException e) {

        logger.log(Level.SEVERE, e.getMessage(), e);

        }

Hi,
I am trying to send HTML string to server using RequestBuilder with JSON but without any success.

Everything works well when in HTML there are no double quotes or other JSON charachters.

So I am trying something like this

RichTextArea area = new RichTextArea();

String htmlToSend = area.getHTML();

JSONObject requestParams = new JSONObject();
requestParams.put("some_key", new JSONString(htmlToSend));

Unfortunately that string is not encoded properly to be safe to send with json

So if value retuned from area.getHTML() contains double quotes like this:

<p><a href="http://www.denic.de/de/domains/recht/index.html" target="_blank">www.denic.de/de/domains/recht/index.html</a></p>

request param looks like

{"some_key":"<p><a href="http://www.denic.de/de/domains/recht/index.html" target="_blank">www.denic.de/de/domains/recht/index.html</a></p>"}

JSONString method toString() on the other hand is calling JsonUtils.escapeValue(value) so that string should be escaped. And If I call escapeValue from JsonUtils by myself
i get string encoded but end up with two double quotes at the beginning and the end of that string..

Any help is welcome,
Thanks,
Milan
