I have a response from a service, using https
rest.on("data", data => {
response = JSON.parse(data);
});
I need parse this response but... I know the final result should be(I get this with postman)...
{ "code": 200,
"msg": "",
"data": [
{
"id": "t4ba",
"devData": {
"id": "bb2as",
"state": "OK"
},
"entries": {
"2019-05-26T19:03:13.9260000": 15,
"2019-05-26T19:03:29.1690000": 26,
"2019-05-26T19:04:16.6880000": 65
}
},
{
"id": "t4ba-2",
"devData": {
"id": "bb2as",
"state": "Underperformance"
},
"entries": {
"2019-05-26T19:03:13.9260000": 25,
"2019-05-26T19:03:29.1690000": 45,
"2019-05-26T19:04:16.6880000": 32
}
}
],
"dateResponse": "2021-03-26T19:04:16.6880000" }
When I run JSON.parse(data)
I get this errror
"errorType": "SyntaxError", "errorMessage": "Unexpected end of JSON input", "trace": [ "SyntaxError: Unexpected end of JSON input", " at JSON.parse ()", " at IncomingMessage. (/var/task/index.js:47:23)", " at IncomingMessage.emit (events.js:315:20)", " at IncomingMessage.EventEmitter.emit (domain.js:467:12)", " at IncomingMessage.Readable.read (internal/streams/readable.js:519:10)", " at flow (internal/streams/readable.js:992:34)", " at resume_ (internal/streams/readable.js:973:3)", " at processTicksAndRejections (internal/process/task_queues.js:80:21)" ]
I think the "data array" field is the problem and I don't know how to solve it.
When I receive a response with empty data:[], everything works fine.
Hmmmm... The answer is easy...
Lets Start:::::
First, looks like you get a lot of data from your service...
On response.on("data"
Data is not complete at first, so, .on("data" "repeat himself" from init to end, then ur data is complete...
code
res.on("data", data => {
someVariable += data;
});
then... in your .on("end"
rest.on("end", () => {
MyJSON = JSON.parse(someVariable);
});
That's all folks.
