使用 node.js 在 IBM Cloud 的 Web 操作中使用 axios
Using axios in a web action in IBM Cloud using node.js
我一直在尝试获得一个简单的网络操作来向 API 发出经过身份验证的 GET 请求(我已经从示例代码中删除了实际的 url 和秘密)。
我在本地成功地 运行,但是当我测试网络操作时,它在记录“调用 axios”后就死掉了。
它没有报告错误,我试图实现一个承诺,认为线程在 api 响应之前就结束了,但没有效果。有什么指点吗?

* @param Cloud Functions actions accept a single parameter, which must be a JSON object.
*
* @return The output of this action, which must be a JSON object.

*/
function main(params) {
getData().then(function(result) {
console.log("In the THEN of original method call");
return "hello";
})
.catch(function(err) {
console.log("In catch of original method call");
});
}
function getData(){
const crypto = require('crypto');
const axios = require('axios');
const secretKey = "ENTER KEY HERE";
const apiId = 99999;
const apiBaseUrl = "https://acmewebservice.com";
const apiPath = "/customer/9";
const apiFullPath = apiBaseUrl + apiPath;
const sharedSecretHash = crypto.createHash('sha256').update(secretKey).digest('hex');
console.log("In getData");
var authToken = apiId + ":" + sharedSecretHash;
return new Promise((resolve, reject) => {
console.log("Calling axios");
axios.get(apiFullPath, {
headers: {
'Authentication': authToken
}
}).then(response => {
console.log("Did this work?")
var x = JSON.stringify(response.data);
console.log(x);
resolve(response);
})
.catch(error => {
console.log("In Catch")
console.log(error);
reject(error);
});
});
你不需要重新包装 axios 调用,它已经是一个承诺。
需要 return
让引擎有效地等待异步调用的结果。
