我已经编写了一些代码，以使用其API在JIRA上创建问题。凭单制作得很好，但是我正在努力将此问题或任何错误传达给用户。我尝试使用答案here无济于事（如代码所示）。
基本上，单击“提交”后，我得到的基础页面没有任何结果，因此无法通知用户其票证是否已创建。我怀疑异步将其弄乱了，因此我为上下文添加了更多内容。
/* Modules */
const express = require('express');
const path = require('path');
const bodyParser = require('body-parser');
const app = express();
const http = require('machinepack-http');
/* app setup */
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static(__dirname + '/public'));
app.set('view engine', 'ejs');
app.get('/', function(req, res){
res.render(path.join(__dirname+'/index'), {results: ''});
});
app.listen(2005, function () {
console.log('Jira Portal listening on port 2005');
});
app.post('/submit', function(req, res){
addAsync(req, res).then((result) => {
console.log("****** JIRA response: ");
console.log(result);// standard JIRA API response
var issueName = result.body.split(",")[1].split(":")[1].replace(/"/g,"");//gets issue name if success (eg. TEST-007)
var issueDesc = result.body.split(",")[1].split(":")[2].replace(/"/g,"").replace(/\}/g,"");//gets error description if error
if(result.body.split(",")[0].split(":")[0].replace(/"/g,"").replace(/\{/g,"") == "errorMessages"){
console.log('ERROR:' + issueDesc); //ERROR:The reporter specified is not a user.
/*
* This is not working, html is outputting the correct html code
* but the user never sees it on their end.
*/
res.render(path.join(__dirname+'/index'), {results: 'ERROR:' + issueDesc},
function(err, html){
if(err){ console.log(err); }
console.log(html);//this html output is correct
res.status(200).send(html);//never see this html on browser
}
);
}else{
// Not tested yet, but assuming probably the same issue occurs
console.log('Created ticket ' + issueName + '. To see this ticket, go to ' + _JIRA_HOST + 'browse/' + issueName);
return res.render(path.join(__dirname+'/results'), {results: 'Created ticket ' + issueName + '. To see this ticket, go to ' + _JIRA_HOST + 'browse/' + issueName});
}
});
});
async function addAsync(req, res){
return await(createJiraIssue(req, res)); //http post method to JIRA (contains a promise)
}
根据要求，使用createJiraIssue()函数（我希望它不需要减少问题中发布的代码量）。
function createJiraIssue(req, res){
var login_data = _JIRA_USER + ":" + _JIRA_PW;
login_data = Buffer.from(login_data).toString('base64');
return new Promise((resolve, reject) => {
http.sendHttpRequest({
url: '/rest/api/2/issue/',
baseUrl: _JIRA_HOST,
method: 'post',
body:{
"fields": {
"project": {
"key": _JIRA_PROJECT
},
"summary": req.body.summary,
"description": req.body.desc,
"issuetype": {
"name": _JIRA_ISSUE_TYPE
},
"reporter": {
"name": req.body.user
},
"components": [{
"id": req.body.component.split('&')[0]
}],
"labels": [req.body.area]
}
},
headers: {
"Authorization": "Basic " + login_data,
'Content-Type': 'application/json'
}
}).switch({
error: function(err){ return reject(err); },
non200Response: function(result){ resolve(result); },
requestFailed: function(){ return reject("request failed"); },
success: function(result){ resolve(result); },
});/*End switch*/
});/*End Promise*/
}
采样结果
{ statusCode: 400,
headers:
{ server: 'servername',

答案 0 :(得分：0)
为什么要使用addAsync函数，这毫无用处只需直接在createJiraIssue request内部使用function并发出请求function async。
