我正在尝试使用AWS客户端网关API从节点js执行AWS REST API。
代码如下：
var apigClientFactory = require('aws-api-gateway-client').default;
let awsbody = JSON.parse(process.argv[2].split('\\').join('') || '{}');
// Loggin to confirm Input
var apigClient = apigClientFactory.newClient({
invokeUrl: awsbody.endPoint, // REQUIRED
accessKey: awsbody.awsAccessKey, // REQUIRED
secretKey: awsbody.awsSecreteKey, // REQUIRED
region: awsbody.awsRegion, // REQUIRED: The region where the API is deployed.
retryCondition: (err) => { // OPTIONAL: Callback to further control if request should be retried. Uses axon-retry plugin.
return err.response && err.response.status === 500;
}
});
var pathParams = awsbody.awsPathParams;
// Template syntax follows url-template https://www.npmjs.com/package/url-template
var pathTemplate = awsbody.awsPathTemplate; // '/api/v1/sites'
var method = awsbody.method; // 'POST';
var additionalParams = { queryParams: awsbody.awsAdditionalParams };
//var additionalParams = {};
var body = awsbody.requestBody;
var output = {};
apigClient.invokeApi(pathParams, pathTemplate, method, additionalParams, body)
.then(function(result) {
// return JSON.parse(result.data);
output.state = result.response.data,
output.header = result.response.headers;
return output
// console.log(result.response.headers)
}).catch(function(result) {
//console.log(result)
// console.log(result.response.data)
// console.log(result.response.status + " - " +
result.response.statusText)
output.state = result.response.data,
output.responsecode = result.response.status,
output.responsetext = result.response.statusText;
return output
});
后执行低于错误：
错误消息：（节点：3424）UnhandledPromiseRejectionWarning：TypeError：无法读取未定义的属性“ data” 在C：\ Servicenow \ nodejs \ awsInvokeRestapi.js：63：40 在process.internalTickCallback（内部/进程/next_tick.js:77:7） （节点：3424）UnhandledPromiseRejectionWarning：未处理的承诺拒绝。引发此错误的原因可能是抛出了一个没有catch块的异步函数，或者是拒绝了一个.catch（）无法处理的承诺。 （拒绝ID：2） （节点：3424）[DEP0018] DeprecationWarning：已弃用未处理的承诺拒绝。将来，未处理的承诺拒绝将以非零退出代码终止Node.js进程。
但是，如果我只是返回结果，则输出没有任何问题。但是在这里，我试图从结果中仅读取必要的信息。
这是整个结果：我只需要数据对象。
