Opencart 的 REST API 生成

Question

我试图为我的客户、类别、产品、优惠券、制造商和所有其他人生成一个 REST API，以便在我的 Android 应用程序中使用它，但我无法获得任何解决方案。谁能告诉我如何在 opencart 3.0.2.0 中创建 API？

Answer 1

在目录 > 控制器 > api文件夹中制作自定义控制器

创建控制器文件名：allproducts.php

您可以复制以下代码并粘贴allproducts.php

<?php

class ControllerApiAllproducts extends Controller {

    private $error = array();

    // All Products

    public function index(){

        $products = array();

        $this->load->language('catalog/product');

        $this->load->model('catalog/product');

        $this->load->model('tool/image');

        $error[]['no_json']= "No JSON";

        $product_total = $this->model_catalog_product->getTotalProducts();

        $results = $this->model_catalog_product->getProducts();

        foreach ($results as $result) {

            if (is_file(DIR_IMAGE . $result['image'])) {

                $image = $this->model_tool_image->resize($result['image'], 40, 40);

            } else {

                $image = $this->model_tool_image->resize('no_image.png', 40, 40);

            }

            $special = false;

            $product_specials = $this->model_catalog_product->getProductSpecials($result['product_id']);

            foreach ($product_specials  as $product_special) {

                //if (($product_special['date_start'] == '0000-00-00' || strtotime($product_special['date_start']) < time()) && ($product_special['date_end'] == '0000-00-00' || strtotime($product_special['date_end']) > time())) {

                    $special = $product_special['price'];

                    //break;

               // }

            }

            $shop_products['shop_products'][] = array(

                'product_id' => $result['product_id'],

                'image'      => $image,

}

我制作了以下 API 及其路径（请参阅 Postman 应用程序）：

1. 所有产品：http ://examples.com/index.php?route=api/allproducts&json

2. 产品编号：http ://examples.com/index.php?route=api/allproducts/productInfo&json&product_id=30

3. 所有类别：http ://examples.com/index.php?route=api/allproducts/categories&json

4. 分类明智的产品：http ://examples.com/index.php?route=api/allproducts/categoryList&json&path=25_28

5. 所有制造商：http ://examples.com/index.php?route=api/allproducts/manufactureList&json

6. 制造商 ID：http ://examples.com/index.php?route=api/allproducts/manufactureInfo&manufacturer_id=11

7. 特殊产品：http ://examples.com/index.php?route=api/allproducts/specialProduct&json
