如何從節點正確調用AWS Api網關？

我想使用aws-api-gateway-client模塊從NodeJS調用AWS api網關。如何從節點正確調用AWS Api網關？

這裏是我的代碼：

module.exports = function(app) { 

    var apigClientFactory = require('aws-api-gateway-client').default; 

    var querystring = require('querystring'); 

    var apigClient = apigClientFactory.newClient({ 
     apiKey: '1234' 
    }); 

    var params = { 
     //This is where any header, path, or querystring request params go. The key is the parameter named as defined in the API 
     userId: '1234' 
    }; 
    var additionalParams = {}; 

    app.get('*', function(req, res) { 
     res.sendfile('./public/index.html'); 
    }); 

    app.post("/customerinfo", function(req, res) { 
     console.log("name: " + req.body["customer_name"]); 

     var body = {"async": true, 
      "crossDomain": true, 
      "url": "https://mystuff.execute-api.us-west-2.amazonaws.com/staging/api", 
      "method": "POST", 
      "headers": { 
      "cache-control": "no-cache" 
     }, 
     "data": querystring.stringify(req.body["customer_name"]) 
    }; 

     apigClient.invokeApi(params, body, additionalParams) 
      .then(function(result){ 
       // Add success callback code here. 
      }).catch(function(result){ 
      // Add error callback code here. 
     }); 
    }); 

};

當我啓動節點服務器，我得到這個錯誤：

/Users/eugene/Desktop/dms/node_modules/aws-api-gateway-client/dist/apigClient.js:84 
    var endpoint = /(^https?:\/\/[^\/]+)/g.exec(invokeUrl)[1]; 
                 ^

什麼是從節點調用AWS API網關的正確方法？

當你調用「newClient」門戶客戶端的工廠的方法，在你的代碼：

var apigClient = apigClientFactory.newClient({ 
    apiKey: '1234' 
});

它預計，在配置對象的關鍵「invokeUrl」。因此，您需要將此密鑰與指定的URL一起作爲此密鑰的值傳遞。例如：你應該試試這個 -

var apigClient = apigClientFactory.newClient({ 
    apiKey: '1234', 
    invokeUrl:'https://xxxxx.execute-api.us-east-1.amazonaws.com' 
});

希望，它可以幫助你解決這個問題。
