Go WordPress

A Go client library for the Wordpress REST API

Upstream Status:

• https://github.com/robbiet480/go-wordpress (stop maintenance)
• https://github.com/sogko/go-wordpress

Installation

go get github.com/soulteary/go-wordpress

Usage

Quick example

package main

import (
  "context"
  "fmt"
  "net/http"

  "github.com/soulteary/go-wordpress/sdk"
)

func main() {

  tp := wordpress.BasicAuthTransport{
    Username: USER,
    Password: PASSWORD,
  }

  // create wp-api client
  client, _ := wordpress.NewClient(API_BASE_URL, tp.Client())

  ctx := context.Background()

  // for eg, to get current user (GET /users/me)
  currentUser, resp, _ := client.Users.Me(ctx, nil)
  if resp != nil && resp.StatusCode != http.StatusOK {
    // handle error
  }

  // Or you can use your own structs (for custom endpoints, for example)
  // Below is the equivalent of `client.Posts.Get(ctx, 100, nil)`
  var obj MyCustomPostStruct
  resp, err := client.Get(ctx, "/posts/100", nil, &obj)
  // ...

  fmt.Printf("Current user %+v", currentUser)
}

For more examples, see package tests.

Authentication

The go-wordpress library does not directly handle authentication. Instead, when creating a new client, pass an http.Client that can handle authentication for you.

Note that when using an authenticated Client, all calls made by the client will include the specified authentication transport token. Therefore, authenticated clients should almost never be shared between different users.

Username/Password or Application Password

A basic authentication (username/password) client for use with the WP-API BasicAuth plugin or Application Passwords plugin is included with the library. An example implementation can be found in example/basicauth/main.go.

OAuth 1.0a

If you use the OAuth 1.0a Server for authentication, you can find an example implementation in example/oauth2/main.go using the oauth1 library (which is very similar to the official OAuth 2.0 library). See the oauth1 docs for complete instructions on using that library.

OAuth 2.0 and JWT

If you are using the JWT plug-in for authentication, you can use the oauth2 library's StaticTokenSource. An example implementation can be found in example/oauth2/main.go. See the oauth2 docs for complete instructions on using that library.

Other authentication styles

For any other authentication methods, you should only need to provide a custom http.Client when creating a new WordPress client.

Pagination

All requests for resource collections (posts, pages, media, revisions, etc.) support pagination. Pagination options are described in the wordpress.ListOptions struct and passed to the list methods directly or as an embedded type of a more specific list options struct (for example wordpress.PostListOptions). Pages information is available via the wordpress.Response struct.

package main

import (
  "context"

  "github.com/soulteary/go-wordpress"
)

func main() {
  tp := wordpress.BasicAuthTransport{
    Username: USER,
    Password: PASSWORD,
  }

  // create wp-api client
  client, _ := wordpress.NewClient(API_BASE_URL, tp.Client())

  ctx := context.Background()

  opt := &wordpress.PostListOptions{
    ListOptions: wordpress.ListOptions{PerPage: 10},
  }
  // get all pages of results
  var allPosts []*wordpress.Post
  for {
    posts, resp, err := client.Posts.List(ctx, opt)
    if err != nil {
      return err
    }
    allPosts = append(allPosts, posts...)
    if resp.NextPage == 0 {
      break
    }
    opt.Page = resp.NextPage
  }
}

Test

Note: Before running the tests, ensure that you have set up your test environment

Prerequisites

• Wordpress 4.x
• WP-API's BasicAuth plugin (for authentication)

Setting up test environment

• Install prequisites (see above)
• Import ./test-data/go-wordpress.wordpress.2015-08-23.xml to your local test Wordpress installation
• Upload at least one media to your Wordpress installation (Admin > Media > Upload)
• Edit one (1) most recent Post to create a revision
• Edit one (1) most recent Page to create a revision

Running tests

# Set test enviroment
export WP_API_URL=http://192.168.99.100:32777/wp-json/
export WP_USER=<user>
export WP_PASSWD=<password>

cd $GOPATH/src/github.com/soulteary/go-wordpress
go test
