Я пытаюсь сделать Http-запрос, используя запрос-обещание внутри цикла for.Но кажется, что если запрос Http занимает много времени, запрос-обещание закрывает соединение.
Это нормально, но я не могу понять, что цикл for снова начинается с 0 после вывода ошибки.
Ниже приведен код
const rp = require('request-promise');
async function stepIterator(processingSteps, documentId) {
var finalResult = null;
for (var step = 0, len = processingSteps.length; step < len; step++) {
if (step === 0 || step === 1 || step == 2 || step == 3) {
try {
console.log('Calling step ', step);
let url = 'http://internal-server:8080/process';
let collection = getCollection(documentId);
let splitText = getSPlit(documentId);
let outputFormat = 'xmi';
let documentObject = await callServer(url, collection, splitText, outputFormat);
finalResult = documentObject;
} catch (error) {
console.log("Error");
}
}
}
return finalResult;
}
async function callServer(url, collection, splitText, outputFormat) {
var options = {
method: 'POST',
uri: url,
headers: {
'Content-Type': 'multipart/form-data',
'Cache-Control': 'no-cache',
'Connection': 'keep-alive '
},
formData: {
collection: collection,
text: splitText,
output: outputFormat
}
};
return rp(options)
}
Полная трассировка ошибки выглядит следующим образом
