A mORMot Wordpress REST API (and WooCommerce API) consumer

Hi,
for my project that uses webservice (based on mORMot) I will have to create users in Wordpress with the same account ( username,pwd,email, etc)  and maybe later to reading/writing WooCommerce data. Therefore  I created a small library to accomplish it.
I tried to use ORM classes for the work with Wordpress records.

The reading looks like this

type 
TWPRESTAPI1_0_3LEGS = class(TWPRESTAPI)       // my class for dealing with Wordpress REST API include providing authentication
...
TSQLWPClient = class(TSQLHttpClientWinHTTP)
...
TSQLRESTAPIUser = class(TSQLRecord)
  protected
    fusername: RawUTF8;
    fname: RawUTF8;
    ffirst_name: RawUTF8;
    fnickname: RawUTF8;
    fslug: RawUTF8;
...

var
     fWP: TWPRESTAPI1_0_3LEGS ;  
     fWPClient : TSQLWPClient;
     fWPUser : TSQLRESTAPIUser;

procedure ReadWPUsers;
begin    
    fWP := TWPRESTAPI1_0_3LEGS.create('WPRestAPI.json'); // WPRestAPI.json - the file containing TSQLRecord that stores Wordpress server, consumer key, secret consumer key etc. 
    fWP.Connect;

    fWPClient := TSQLWPClient(fWP.getWAPIClient('users', '{"search":"*eva*","orderby":"username}'));   //'users' is route of WP REST API and '{"search":...'  is filter
 
    fWPUser := TSQLRESTAPIUser.CreateAndFillPrepare(fWPClient,'',[]);
end;

the updating like this:

procedure UpdateWPUser;
begin
  if assigned( fWPUser) then
  begin
    fWPUser.FillRewind;
    while fWPUser.FillOne do
    begin
      if fWPUser.username=EditWPUsername.text then
      begin
        fWPUser.description := EditWPdescription.text;
        fWPClient.Update(fWPUser);
      end;
    end ;
  end;
end;

I had to only  take care of the authentication of the requests, everything else was pretty simple thanks mormot.

hereby is source https://github.com/Eva-F/mormot-WP-REST-API
maybe it helps somebody

a little remark:
I am not good in the writing of commentaries neither in my native language let alone in English.
I know only a small fraction of mormot, so some part of my code could use routines of mormot better and more effectively

Thanks for sharing.

BTW, isn't CopyVarRec() leaking memory, when processing vtPWideChar, vtUnicodeString?

Thanks for the warning, I will take look into - in this case I think that in SynCommons is a suitable subroutine for this purpose, but I could not find it

I did not understand the purpose of this function, and its use case...

I will try to explain my idea:
I have intended  to call the CallbackGet function that uses open array of TVarRec as a parameter.

function TSQLRestClientURI.CallBackGet(const aMethodName: RawUTF8;
  const aNameValueParameters: array of const; ...): integer;

Rather then explicitly enumerate  all  name, value pairs I would prefer to add them gradually one by one based on the actual authentication stage. Therefore  each NameValue pair is copied into a FParameters array

    fParameters: array of TVarRec;

and afterwards passed as an aNameValueParameters. 

fOauthClient.CallBackGet('request', fParameters, lResponse)

I have fixed the unsatisfactory releasing of fParameters and there are no memory leaks now.

Further I have discovered a bug in OAuth1 plugin and when I have checked it on Github, I have found out that there is a new version of Oauth1 plugin available and that this new version changed the way the signature is created at the third leg of authetication. I have also added  the support for OAuth1 plugin version 0.2.1 into source code.

You could use a TDocVariantData to store the array and convert it to an array of const.

Re: A mORMot Wordpress REST API (and WooCommerce API) consumer

Hi EvaF,
i'm testing your mormot-WP-REST-API.
I try to follow your instruction on readme, installed the plugin (but some version of plugin is updated), generate the key, edit json configuration file.
I have no response when i try to "get WP users".
I get error 404: rest_no_route if i try to create new user.
I read well woocommerce customers with "get Woo Customers".
I get error 404: woocommerce_api_no_route if i try to create new customer.
I think that i mistake something in the configuration file or in wordpress configuration.
Can you help me to understand?
thanks

Re: A mORMot Wordpress REST API (and WooCommerce API) consumer

I checked only WordpressREST ( sorry - a few time). I have installed new version (Oauth 0.3.0, Wordpress 4.7 +  Mormot Nigth Build -mORMot_and_Open_Source_friends_2016-12-21_193435_df194baa76) and made a couple of the small changes in WordpressREST sources.
The adding, updating and listing Wordpress users works now.

About the Error 404: rest_no_route
Please check your Wordpress endpoint address
=[WP-REST-API-Url] - http[https]://[your-WP-server]/wp-json/ in WPRESTAPI.json
and
=[WOO-REST-API-Url] - http[https]://[your-WP-server]/wc-api/[Woocommerce API version]/ in WooRESTAPI.JSON     

f.e.

Hi,
