在AWS Lambda中使用async/await进行Woocommerce API调用

Question

我们在调用中对一些fs函数使用了一些async/await语法，并希望引入一个Woocommerce API调用并使用async/await，但我正在努力解决这个语法问题。

  const WooCommerceAPI = require('woocommerce-api');

  exports.handler = async (event, context, callback) =>{

      const orderFileName ="1141";
      let wooOrderDetails;

      var WooCommerce = new WooCommerceAPI({
        url: 'http: //example.com',
        consumerKey: 'ck_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        consumerSecret: 'cs_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        wpAPI: true,
        version: 'wc/v1'
    });

      WooCommerce.getAsync('orders/' + orderFileName).then(function(result){
        return JSON.parse(result.toJSON().body);
        wooOrderDetails = JSON.parse;
        console.log(wooOrderDetails);

        let wooOrderID = wooOrderDetails.id;
        let wooOrderNumber = wooOrderDetails.number;
        let Email = wooOrderDetails.billing.email;
    });

    // Update order as Completed
      const status ={
        status: 'completed'
    };

    // Update WooCommerce Order Notes via API
    WooCommerce.post('orders/' + orderFileName, status, function (err, states, res){
        if (err) throw err;
        console.log('Update WooCommerce order with status');
        const data ={ note: 'Status Updated';
      });

        WooCommerce.post('orders/' + orderFileName + '/notes', data, function (err, data, res){
            if (err) throw err;
            else console.log('Woo Order Notes Update:');
      });
    });
    });
  };

NPM module有一些异步示例，但我无法让它们正常工作。我主要认为函数的返回过程存在问题

Answer 1

基本上，您将xyzAsync(a,b).then(result => {code})转换为result = await xyzAsync(a,b); code;。因此，您的第一个getAsync (其中包含一些小错误，顺便说一下)是：

const result = await WooCommerce.getAsync('orders/' + orderFileName)
const wooOrderDetails = JSON.parse(result.toJSON().body);
console.log(wooOrderDetails);
let wooOrderID = wooOrderDetails.id;
let wooOrderNumber = wooOrderDetails.number;
let Email = wooOrderDetails.billing.email;

以下是可能的错误修复和异步等待样式的工作代码：

exports.handler = async(event, context, callback) => {

    const orderFileName = "1141";
    let wooOrderDetails;

    const WooCommerce = new WooCommerceAPI({
        url: 'http: //example.com',
        consumerKey: 'ck_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        consumerSecret: 'cs_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
        wpAPI: true,
        version: 'wc/v1'
    });

    const result = await WooCommerce.getAsync('orders/' + orderFileName);
    wooOrderDetails = JSON.parse(result.toJSON().body);
    console.log(wooOrderDetails);
    let {id: wooOrderID, number:wooOrderNumber, billing} = wooOrderDetails;
    let {email} = billing;

    // Update order as Completed
    const status = {
        status: 'completed'
    };

    // Update WooCommerce Order Notes via API
    try {
        const statusResults = await WooCommerce.post('orders/' + orderFileName, status);
        console.log('Update WooCommerce order with status');
        const data = {note: 'Status Updated'};

        const notesResults = await WooCommerce.post('orders/' + orderFileName + '/notes', data);
        console.log('Woo Order Notes Update:');
    } catch (e) {
        // throw error or take actions you want
    }
};
