I'm working with bricklink api http://static.bricklink.com/alpha/default/api_wiki.html
I'm unable to implement it in flutter, due to lack of expertise. Here is the request implementation in node.js and I want to replicate this in flutter.
const OAuth = require('oauth');
const fs = require('fs');
const http = require('http');
const host = '127.0.0.1';
const port = '7070';
const server = http.createServer((_req, res) => {
var oauth = new OAuth.OAuth('', '', 'consumer_key', 'consumer_secret', '1.0', null, 'HMAC-SHA1');
oauth.get('https://api.bricklink.com/api/store/v1/categories', 'token_value', 'token_secrete', function(error, data, res) {
if (error) return false;
var json = JSON.parse(data);
saveData(json);
});
function saveData(data) {
const jsonData = JSON.stringify(data);
fs.writeFileSync('inventory.json', jsonData);
res.statusCode = 200 || 201;
// res.setHeader('Content-Type', 'text/plain');
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
res.end('Done');
console.log('Done');
}
});
I want to implement this request in flutter.
Thank You

I am trying to create a user in JRS using Axios, I have managed to run reports but now I am trying to create users, my code is as follows, is there any reason why it does not work?
const express = require('express');
const axios = require("axios");
const app = express();
let bodyParser = require("body-parser");
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true}))
app.get('/prueba', function(req,res){
res.sendFile(__dirname+"/prueba.html");
});
app.post('/form-submit', async function(req,res){
try {
const url = "http://localhost:8080/jasperserver/rest_v2/users/jose"
let params = {
fullName:"Joe User",
emailAddress:"juser#example.com",
externallyDefined:false,
enabled:false,
password:"mySecretPassword",
roles:[
{"name":"ROLE_USER", "tenantId":"organización_1"}]
}
const file = await axios.put(url, {
params: params,
responseType: "stream",
auth:{
username: "jasperadmin",
password: "jasperadmin"
}
})
res.writeHead(200,{"Content-Type":"application/json"})
file.data.pipe(res)
} catch (error) {
console.log(error)
}
});
app.listen(7000)
I am using dio to make a network request. In testing phases I was using local host port 3000. I was using a javascript file and node to run it in testing mode. I would simply run node on the javascript file it would fire up the port at it would work. This was great but whenever I run it on a real device it does not work. So I am assuming I need to change it to something else for release...? I am new bare with me. Any suggestion or guidance would be helpful thank you.
const muxServerUrl = 'http://localhost:3000';
initializeDio() {
BaseOptions options = BaseOptions(
baseUrl: muxServerUrl,
connectTimeout: 8000,
receiveTimeout: 5000,
headers: {
"Content-Type": contentType, // application/json
},
);
_dio = Dio(options);
}
Implementation
late Response response;
try {
// print(response);
response = await _dio.post(
"/assets",
data: {
"videoUrl": videoUrl,
},
);
} catch (e) {
print('ran 2');
throw Exception('Failed to store video on MUX');
}
if (response.statusCode == 200) {
print('ran 4');
VideoData videoData = VideoData.fromJson(response.data);
String status = videoData.data!.status;
while (status == 'preparing') {
await Future.delayed(Duration(seconds: 1));
videoData = (await checkPostStatus(videoId: videoData.data!.id))!;
status = videoData.data!.status;
}
print('Video READY, id: ${videoData.data!.id}');
return videoData;
}

localhost is what's called your loopback address and that's only working because you are running the application on your machine. When you release the app you have to host your Nodejs app in some server and use the IP address of that server instead. Before you host that app I encourage you to spend more time making sure that it secure.
If you just want to run the app on an Android emulator you can use 10.0.2.2 to reach the hosting machine loopback
I am following a tutorial from Coding Garden. There he writes to a database and sends it then back to the client.
When I try to do it, I do not get a respond from the server. I guess there has been a mix up in my code.
When I go to localhost/5000/posts there is no database. Why do I not get an errormessage, or a database?
Best regards
Expected Result:

client code
const form = document.querySelector('form');
const loadingElement = document.querySelector(".loading");
const API_URL = "http://localhost:5000/posts";
loadingElement.style.display = "none";
form.addEventListener('submit', (event) => {
event.preventDefault();
const formData = new FormData(form);
const name = formData.get('name');
const content = formData.get('content');
const post = {
name,
content
};
form.style.display = "none";
loadingElement.style.display= "";
fetch(API_URL, {
method: "POST",
body: JSON.stringify(post),
headers: {
"content-type": "application/json"
}
}).then(response => response.json())
.then(createdPost => {
console.log(createdPost);
});
});
server code
const express = require("express");
const cors = require('cors');
const monk = require("monk");
const app = express();
const db = monk("localhost/posts");
const posts = db.get("posts");
app.use(cors());
app.use(express.json());
app.get("/", (req, res) => {
res.json({
message: "Post"
});
});
function isValidPost(post){
return post.name && post.name.toString().trim() !== "" &&
post.content && post.content.toString().trim() !=="";
}
app.post("/posts", (req, res) => {
if (isValidPost(req.body)){
const post = {
name: req.body.name.toString(),
content: req.body.content.toString(),
created: new Date()
};
//console.log(post);
posts
.insert(post)
.then(createdPost => {
res.json(createdPost);
});
}else {
res.status(422);
res.json({
message: "Hey, Titel und Inhalt werden benötigt!"
});
}
});
app.listen(5000, () => {
console.log('Listening on http://localhost:5000');
});
You forgot to handle the case when post.insert(...) fails and rejects. In this case no response is sent from your server and the request will hang. Add the following:
posts
.insert(post)
.then(createdPost => {
res.json(createdPost);
})
.catch(err => {
console.log(err);
res.status(500).json({errorMessage: err.message});
});
handle the fetch method with catch. It probably goes to catch.
fetch().then().catch(err => ...)
In below code, "agent.add" is not working but "console.log" is working. I have added promise with resolve and reject, but still its not working. I have tried different ways but multiple response from firestore, not able to send it to user. Able to see logs in firebase but not in dialogflow.
const {Firestore} = require('#google-cloud/firestore');
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const admin = require('firebase-admin');
admin.initializeApp();
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging
statements
const firestore = new Firestore();
const settings = {/* your settings... */
timestampsInSnapshots: true};
firestore.settings(settings);
exports.dialogflowFirebaseFulfillment =
functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' +
JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
const db = admin.firestore();
```
function welcome(agent) {
agent.add(`Welcome to my agent!`); // not working
console.log("Welcome Agent");
const num = agent.parameters.number;
let usersRef = db.collection('add');
let query = usersRef.where('Number', '==', num);
return new Promise((resolve,reject)=>{ // not working
return query.get()
.then(querySnapshot => {
if (querySnapshot.empty) {/*
const timestamp = querySnapshot.get('created_at');
const date = timestamp.toDate();*/
console.log('No matching documents.');
agent.add(`No Matching Documents`);
return;
}
querySnapshot.forEach(doc => {
const line1 = doc.get('Line1');
const line2 = doc.get('Line2');
const explain = doc.get('explanation');
console.log('Line1: ', line1); //this works
console.log('Line2: ', line2); //this works
console.log('explain: ', explain); //this works
agent.add(`your response is ` +doc.get('Line1')); //not working
agent.add(`Final Response - ${line2}`); //not working
agent.add(doc.get('explanation')); //not working
});
resolve('resolved');
})
.catch(err => {
console.log('Error getting documents', err);
reject(err);
});
});
}
Issue is resolved now. Added return statement in the last agent.add and it is working. Thanks.
agent.add(your response is +doc.get('Line1'));
agent.add(Final Response - ${line2});
return agent.add(doc.get('explanation'));
I am very new to React Native and I am trying to figure out how to connect my front end to my back end. I realize I may have my folder structure set up oddly but the connection works and I can fetch data from the database but when I attempt a post, it throws a 500 error. I cannot seem to figure out what is happening with it. If anyone has some insight I would greatly appreciate it. The post method console logs the req.body and "Here we are" in the controller file but fails immediately after that.

The problem is you mixed 2 commands for creating a new document
Instead of using both new and create like this:
let tweet = await new Tweet.create(createdTweet);
You should use only 1 of them like so:
let tweet = await Tweet.create(createdTweet);
tweet.save();
Or:
let tweet = new Tweet(createdTweet);
await tweet.save();
