Using HTTP PUT on an endpoint

Hi!   I've been trying to figure out how to edit a post directly from an endpoint. I not quite familiar with HTTP request over javascript, and the documentation (Updating message using HTTP PUT) is...

    I meant you need to use an endpoint that is hosted outside of the community to make the back-channel access token request. We currently restrict endpoints from calling .lithium.com domains for security reasons.

     

    If you are not able to host your own endpoint to make the access token request, you could try hitting the REST v1 messages/id/[message-id]/edit endpoint directly on the community (not through api.lithium.com) to make your message edit.

jQuery is not available in endpoints, since endpoint logic executes server-side (unless you are returning html with a script tag that runs the javascript, then you'll need to include a link to a jQuery script).

 

If you want to make your call in the browser, you should be able to use jQuery if you use the liaAddScript directive in a custom component(you can find documentation for the liaAddScript directive in the freemarker documentation by clicking on Refer > Directives). You can use the jQuery lithium puts on the page by doing something like this (you'll need to tweak it a bit to make it work):

 

<@liaAddScript>
    ;(function($) {
     $.ajax({
       method: 'put',
       url: 'https://api.lithium.com/community/2.0/${myCommunityId}/messages/5909',
       headers: {
        'client-id': '${clientId}'
         'authorization': 'Bearer ' + $.cookie('litok');
       },
       data&colon; { 'data': { 'type': 'message', 'subject', 'my changed subject' } },
       dataType: 'json',
       beforeSend: function (jqXHR, settings) {
         $(this).addClass('loading');
       },
       success: function (data) {
         if (data.status == 'success') {
           // do something with data  
	 },
        error: function (jqXHR, textStatus, errorThrown) {
          $('body').trigger('displayModalError', ["${text.format("error.exception.title")}"]);
        },
	complete: function(jqXHR, textStatus) {
          $(this).removeClass('loading');
        }
     });
    })(LITHIUM.jQuery);
</@liaAddScript>

Thanks DougS,

 

Looks like my problem is that I don't have the oauthAccessToken. I think I'm almost there, using the endpoint and plain javascript I was able to get the 'autorization_code', but when I do the POST /accessToken call I'm getting an internal server error.

 

I'm working with an endpoint because I don't need to display anything on our community. I'm working on an automated way to replace broken links on our community, so basically I'm pulling the content then using javascript to make the replacements and now I'm trying to write the message body back to the community.

 

Here's what I'm doing.

 

1. I'm using an XMLHttpRequest to send the GET /authorize request. I'm using a dummy redirect_uri because I want to do all the processing on the same endpoint, so I'm getting the authorization code from the 'responseURL'

2. I'm using that authorization code for the POST /accessToken request but I keep getting a 'Internal server error' ({"status":"Internal Server Error","message":"Internal Server Error","statusCode":500}) -not very descriptive-

 

var requestBody = {"client_id" : "<my client ID>",
                  "client_secret" : "<my client secret>",
                  "code" : authorization_code,
                  "redirect_uri" : "http://<my stage community URL>/",
                  "grant_type" : "authorization_code",
                  "state" : "someUniqueInfoAboutTheState"};

xhr2 = new XMLHttpRequest();
xhr2.open('POST',encodeURI('https://api.lithium.com/auth/v1/accessToken'),true);
xhr2.setRequestHeader('Content-Type', 'application/json');
xhr2.setRequestHeader('client-id', '<my client ID>');

xhr2.onload = function(aEvt) {    
     if(xhr2.status == 200) {        
        console.log("Response URL  = " + xhr2.responseURL);        
      }
     else {      
      console.log("Error loading page\n");    
    }  
};

xhr2.send(JSON.stringify(requestBody));

I'm decoding the authorization code before sending it.

 

Any ideas?
