如何从节点正确调用aws api网关

我在下面的节点代码中调用aws api网关：

module.exports = function(app) { var apigClientFactory = require('aws-api-gateway-client').default; var querystring = require('querystring'); 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://myurl.execute-api.us-west-2.amazonaws.com/staging/api", "method": "POST", "headers": { "cache-control": "no-cache" }, "data": querystring.stringify(req.body["customer_name"]) }; var apigClient = apigClientFactory.newClient({ apiKey: '1234', invokeUrl:'https://myurl.execute-api.us-west-2.amazonaws.com/staging/api' }); apigClient.invokeApi(params, body, additionalParams) .then(function(result){ // Add success callback code here. }).catch( function(result){ // Add error callback code here. }); }); }; 

我得到以下错误：

 TypeError: method.toUpperCase is not a function at Object.apigClientFactory.newClient.apigClient.invokeApi (/Users/eugene/Desktop/dms/node_modules/aws-api-gateway-client/dist/apigClient.js:117:20) at Object.handle (/Users/eugene/Desktop/dms/app/routes.js:36:20) at next_layer (/Users/eugene/Desktop/dms/node_modules/express/lib/router/route.js:113:13) at Route.dispatch (/Users/eugene/Desktop/dms/node_modules/express/lib/router/route.js:117:5) at /Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:222:24 at Function.proto.process_params (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:288:12) at next (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:216:19) at next (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:202:18) at Layer.staticMiddleware [as handle] (/Users/eugene/Desktop/dms/node_modules/serve-static/index.js:51:61) at trim_prefix (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:263:17) at /Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:225:9 at Function.proto.process_params (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:288:12) at next (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:216:19) at Layer.methodOverride [as handle] (/Users/eugene/Desktop/dms/node_modules/method-override/index.js:75:5) at trim_prefix (/Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:263:17) at /Users/eugene/Desktop/dms/node_modules/express/lib/router/index.js:225:9 

什么是最合适的方式来做到这一点，以避免得到这个错误？

传递给invokeApi方法的参数不是客户端中预期的方法签名。 应该是这样的，

 module.exports = function(app) { var apigClientFactory = require('aws-api-gateway-client').default; var querystring = require('querystring'); 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://myurl.execute-api.us-west-2.amazonaws.com/staging/api", "method": "POST", "headers": { "cache-control": "no-cache" }, "data": querystring.stringify(req.body["customer_name"]) }; var apigClient = apigClientFactory.newClient({ apiKey: '1234', invokeUrl: 'https://myurl.execute-api.us-west-2.amazonaws.com/staging/api' }); >>>> apigClient.invokeApi(params, '/customerinfo', 'POST', additionalParams, body) .then(function(result) { // Add success callback code here. }).catch(function(result) { // Add error callback code here. }); }); }; 

我希望它有帮助。

你可能要仔细检查你的参数invokeApi。 它应该是：apigClient.invokeApi（params，pathTemplate，method，additionalParams，body）
