在IBM Cloud中使用Node.js在web操作中使用axios

Question

我一直试图获得一个简单的web操作来向API发出一个经过身份验证的get请求（我已经从示例代码中删除了实际的url和秘密）。

我已经在本地成功地运行了这一点，但是当我测试web动作时，它只是在记录“调用Axios”之后死亡。

它不会报告错误，我尝试实现一个承诺，认为线程在api响应之前就结束了，但没有效果。有什么线索吗？

    /**
      *
      * main() will be run when you invoke this action
      *
      * @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);
                    });
            });

您不需要重新包装axios调用，这已经是一个承诺了。

需要return来使引擎有效地等待异步调用的结果。

js prettyprint-override">
     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;
            
                    console.log("Calling axios");
                    return axios.get(apiFullPath, {
                        headers: {
                            'Authentication': authToken
                            }
                        }).then(response => {
                            console.log("Did this work?")
                            var x = JSON.stringify(response.data);
                            console.log(x);
                            return response;

                        console.log("In Catch")
                        console.log(error);

                    });
