开始使用

添加依赖

在您的 Flutter 项目的 pubspec.yaml 文件中添加以下依赖项:

dependencies:
  ...
  woosignal_shopify_api: ^2.2.1

导入包

在 Dart 文件中导入 woosignal_shopify_api 包:

import 'package:woosignal_shopify_api/woosignal_shopify_api.dart';

使用示例

初始化 WooSignal

首先,您需要初始化 WooSignal Shopify API 实例并传入您的应用密钥(app key):

await WooSignalShopify.instance.init(appKey: "your app key");

获取产品列表

下面是一个简单的例子,展示如何获取产品列表并在 UI 中显示第一个产品的名称:

class _MyHomePageState extends State<MyHomePage> {
  String? _productName;

  _incrementCounter() async {
    // 初始化 WooSignal Shopify API
    await WooSignalShopify.instance.init(appKey: "your app key");

    // 调用 API 获取产品列表
    ShopifyProductResponse? shopifyProductResponse =
        await WooSignalShopify.instance.getProducts();

    if ((shopifyProductResponse?.products ?? []).isNotEmpty) {
      _productName = shopifyProductResponse?.products?[0].title ?? "";
    }
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text('Tap the light bulb to get a product'),
            if (_productName != null)
              Text(
                'Shopify product :\n $_productName',
              ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: Icon(Icons.lightbulb_outline),
      ),
    );
  }
}

示例 Demo

以下是完整的 Flutter 应用示例,展示了如何使用 woosignal_shopify_api 获取和显示 Shopify 产品:

import 'package:flutter/material.dart';
import 'package:woosignal_shopify_api/models/response/shopify_product_response.dart';
import 'package:woosignal_shopify_api/woosignal_shopify_api.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'WooSignal Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'WooSignal Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({super.key, required this.title});

  final String title;

  @override
  createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String? _productName;

  _incrementCounter() async {
    // 初始化 WooSignal Shopify API
    await WooSignalShopify.instance.init(appKey: "your_app_key");

    // 调用 API 获取产品列表
    ShopifyProductResponse? shopifyProductResponse =
        await WooSignalShopify.instance.getProducts();

    if ((shopifyProductResponse?.products ?? []).isNotEmpty) {
      _productName = shopifyProductResponse?.products?[0].title ?? "";
    }
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text('Tap the light bulb to get a product'),
            if (_productName != null)
              Text(
                'Shopify product :\n $_productName',
              ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: Icon(Icons.lightbulb_outline),
      ),
    );
  }
}

此示例展示了如何从 Shopify 获取产品列表并在点击按钮时更新 UI 显示第一个产品的名称。请确保替换 "your_app_key" 为您自己的应用密钥。

在Flutter项目中集成Shopify API,使用woosignal_shopify_api插件可以方便地与Shopify商店进行交互。以下是一个简单的代码案例,展示了如何使用该插件进行基本的API调用。

首先,确保你的Flutter项目已经添加了woosignal_shopify_api依赖。在pubspec.yaml文件中添加以下依赖:

dependencies:
  flutter:
    sdk: flutter
  woosignal_shopify_api: ^最新版本号 # 请替换为实际的最新版本号

然后,运行flutter pub get来安装依赖。

接下来,在你的Flutter项目中,你可以按照以下步骤使用woosignal_shopify_api插件:

  1. 导入插件

在你的Dart文件中导入插件:

import 'package:woosignal_shopify_api/woosignal_shopify_api.dart';
  1. 初始化Shopify客户端

你需要提供Shopify商店的域名和访问令牌来初始化客户端。通常,这些信息会从用户登录或设置中获取。

class ShopifyService {
  ShopifyClient? _shopifyClient;

  Future<void> initializeShopifyClient(String domain, String accessToken) async {
    _shopifyClient = await ShopifyClient.create(
      domain: domain,
      accessToken: accessToken,
    );
  }

  ShopifyClient? get shopifyClient => _shopifyClient;
}
  1. 进行API调用

一旦客户端初始化完成,你就可以使用它来进行各种API调用。例如,获取商店的产品列表:

class ProductRepository {
  final ShopifyService _shopifyService;

  ProductRepository(this._shopifyService);

  Future<List<Product>> fetchProducts() async {
    final shopifyClient = _shopifyService.shopifyClient;
    if (shopifyClient == null) {
      throw Exception('Shopify client is not initialized.');
    }

    final response = await shopifyClient!.graphQLQuery(
      query: """
      query {
        products(first: 10) {
          edges {
            node {
              id
              title
              handle
              images(first: 1) {
                edges {
                  node {
                    originalSrc
                  }
                }
              }
              variants(first: 1) {
                edges {
                  node {
                    price
                  }
                }
              }
            }
          }
        }
      }
      """,
    );

    // 解析响应数据(这里只是简单示例,实际项目中应更详细地处理错误和数据解析)
    if (response.hasErrors) {
      throw Exception('GraphQL query failed: ${response.errors!.join('\n')}');
    }

    final data = response.data!['products']['edges'] as List;
    return data.map((edge) {
      final node = edge['node'] as Map<String, dynamic>;
      return Product(
        id: node['id'] as String,
        title: node['title'] as String,
        handle: node['handle'] as String,
        imageSrc: node['images']['edges'].isNotEmpty
            ? node['images']['edges'][0]['node']['originalSrc'] as String
            : '',
        price: node['variants']['edges'].isNotEmpty
            ? node['variants']['edges'][0]['node']['price'] as String
            : '',
      );
    }).toList();
  }
}

class Product {
  final String id;
  final String title;
  final String handle;
  final String imageSrc;
  final String price;

  Product({
    required this.id,
    required this.title,
    required this.handle,
    required this.imageSrc,
    required this.price,
  });
}
  1. 使用Repository

在你的UI层或业务逻辑层中使用ProductRepository来获取产品列表并显示:

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: ShopifyProductList(),
    );
  }
}

class ShopifyProductList extends StatefulWidget {
  @override
  _ShopifyProductListState createState() => _ShopifyProductListState();
}

class _ShopifyProductListState extends State<ShopifyProductList> {
  late ShopifyService shopifyService;
  late ProductRepository productRepository;
  List<Product> products = [];

  @override
  void initState() {
    super.initState();
    shopifyService = ShopifyService();
    productRepository = ProductRepository(shopifyService);

    // 假设你已经有了domain和accessToken
    final String domain = 'your-shopify-store.myshopify.com';
    final String accessToken = 'your-access-token';

    shopifyService.initializeShopifyClient(domain, accessToken).then((_) {
      fetchProducts();
    });
  }

  Future<void> fetchProducts() async {
    try {
      final fetchedProducts = await productRepository.fetchProducts();
      setState(() {
        products = fetchedProducts;
      });
    } catch (e) {
      print('Error fetching products: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Shopify Products'),
      ),
      body: ListView.builder(
        itemCount: products.length,
        itemBuilder: (context, index) {
          final product = products[index];
          return ListTile(
            leading: Image.network(product.imageSrc),
            title: Text(product.title),
            subtitle: Text('Price: \$${product.price}'),
          );
        },
      ),
    );
  }
}

请注意,上述代码是一个简化的示例,用于展示如何使用woosignal_shopify_api插件进行基本的Shopify API调用。在实际项目中,你需要处理更多的错误情况、优化数据解析,并可能需要添加更多的功能和API调用。同时,确保你的Shopify商店的域名和访问令牌是安全存储和管理的。
