Question

我尝试使用aws-api-gateway-client模块从NodeJS调用AWS api网关。

这是我的代码：

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.
        });
    });

};

一旦启动节点服务器，我就会收到此错误：

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

从Node调用AWS Api Gateway的正确方法是什么？

Answer 1

当您在代码中调用网关客户端工厂的'newClient'方法时：

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

它期望配置对象中的键'invokeUrl'。因此，您需要将此键与指定的URL一起作为此键的值传递。例如：你应该试试这个 -

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

希望，它可以帮助您解决此问题。

在另一条路径上，为什么不直接将API-Gateway的API作为休止调用？只需调用api网址，然后在标头中将密钥作为“ x-api-key”传递即可。这将使事情变得简单而容易被其他开发人员理解。
