Closed guitar9 closed 6 years ago

guitar9 commented 6 years ago

Hi i get following error when i use it with react native. This is only with client.journys(..). client.locations(..) works fine.

This error is only when i am not in dubugging mode. When i am in debugging mode it works. This is my code:

const createClient = require('hafas-client')
const dbProfile = require('hafas-client/p/db')
const client = createClient(dbProfile)
const münchenHbf = {
  type: 'station',
  id: '008000261',
  name: 'München Hbf',
  locations: {
    type: 'location',
    latitude:48.140364,
    longitude:11.558735
  }
}

const münchenPassing = {
  type: 'station',
  id: '008004158',
  name: 'München-Pasing',
  locations: {
    type: 'location',
    latitude:48.150036,
    longitude:11.461624
  }
}
const opt = {
  //var date2 = new Date('2018-12-17T03:24:00');
    when: new Date('2018-05-29T06:40:00'),

    },
    tickets: false, // return tickets? only available with some profiles
    polylines: false // return a shape for each leg?
}
    client.journeys(münchenPassing, münchenHbf, opt)
    .then((arr)=>{
      console.log('===============arr=====================');
      console.log(arr);

Which version of hafas-client do you use?

derhuerst commented 6 years ago

cannot reproduce.

guitar9 commented 6 years ago

i am using react native and the version is 2.8.0 but i made some changes. import buffer, import random-bytes, ...

https://github.com/guitar9/hafas-client

Now i get the Error JSON Parse error: Unrecongnized token '?'

if I change

'Accept-Encoding': 'gzip, deflate',

to

'Accept': 'application/json',

i get the error PARSE

guitar9 commented 6 years ago

This is the header which is send from a phone with the Deutsche Bahn App. With this header i get the same error.

guitar9 commented 6 years ago

the weird thing is when i change 'Accept-Encoding': 'gzip, deflate' to 'Accept-Encoding': 'application/json' it goes, But only in debug Mode. In normal mode i get error "PARSE"

guitar9 commented 6 years ago

if I commend out the error part i get error "undefined is not a object (evaluating 'b.svcResL[0].res)"

        .then((b) => {
            console.log('=============here is error=======================');
            console.log(b);
            console.log('====================================');
            // if (b.err) {
            //  err.message = b.err
            //  throw err
            // }
            // if (!b.svcResL || !b.svcResL[0]) {
            //  err.message = 'invalid response'
            //  throw err
            // }
            // if (b.svcResL[0].err !== 'OK') {
            //  err.message = b.svcResL[0].errTxt || b.svcResL[0].err
            //  throw err
            // }
            const d = b.svcResL[0].res
            const c = d.common || {}

            if (Array.isArray(c.remL)) {
                d.remarks = c.remL.map(rem => profile.parseRemark(profile, rem))
            }
            if (Array.isArray(c.opL)) {
                d.operators = c.opL.map(op => profile.parseOperator(profile, op))
            }
            if (Array.isArray(c.prodL)) {
                const parse = profile.parseLine(profile, d.operators)
                d.lines = c.prodL.map(parse)
            }
            if (Array.isArray(c.locL)) {
                const parse = loc => profile.parseLocation(profile, loc, d.lines)
                d.locations = c.locL.map(parse)
            }
            return d
        })

I am willing to make hafas-client work in react-native without any modifications. I will create a branch for you to try.

okay thank you :)

In the react-native-browser branch, I've included ponyfills for Buffer and Symbol. Keep in mind that it branches off next, so it will have minor incompatibilities with hafas-client@2.8.0.

Will look into the HTTP headers thing.

guitar9 commented 6 years ago

get now error: Project :app declares a dependency from configuration 'compile' to configuration 'default' which is not declared in the descriptor for project :react-native-randombytes Maybe this problem is only for me because already linked react-native randombytes...

But after installing react-native-randombytes i get error undefined is not a object ( evaluating b.svcResL[0].res)

derhuerst commented 6 years ago

What about now? I pushed c78f64d.

guitar9 commented 6 years ago

I deleted the folder hafas-client and installed it again with

npm install git://github.com:public-transport/hafas-client.git#react-native-browser --save

how ever now i get error cant find variable Buffer.

Can't find variable: Buffer

tried to change .json() to .text() and comment out //'Accept-Encoding': 'gzip, deflate',

But only in debugging mode. In production mode i get same error "PARSE". This is really weird.

I have different bodys in debug mode and in production mode. Out date and Out Time is: Invalid Date in production mode and the checksum is in production mode and debug mode not the same.

I have uploaded a comparssion between the two bodys.

Which debug and production mode are you referring to?

Out date and Out Time is: Invalid Date in production mode [...].

This is very weird. Will try to figure out why.

In the meanwhile, can you try to, instead of the react-native-browser branch, just use hafas-client@next and node-libs-react-native?

Which debug and production mode are you referring to?

If I run my app on a device I can open dev menu and start debugger mode on device. At http://localhost:8081/debugger-ui/ I see then what i have logged out.

tried to install hafas-client@next and node-libs-react-native. I had to install es6-symbol and require it in loyalty-cards and comment out
"//'Accept-Encoding': 'gzip, deflate'" in request.js

Than i have the same problem like before. In debug mode everything is fine but in normal mode the checksum and the Out date and Out time are not correct

Can you log the response by and send it? The appropriate place would be here: https://github.com/public-transport/hafas-client/blob/c78f64d12a4e4b1b835731b39dd90030b4d5117d/lib/request.js#L67

You can log the response like this:

    return fetch(url, req)
    .then((res) => {
        err.statusCode = res.status
        if (!res.ok) {

problem was package luxon.

I've had a look into this once more.

I successfully ran hafas-client@3.0.0-alpha.9 – installed via npm i hafas-client@next – on the device and managed to fetch departures. I added node-libs-react-native to the config and used the global shims. Will add a notice about this to the readme.

I assume all other errors are related to specifics of your local setup. I'm willing to help debug this, but only with comprehensive info.

Hello @derhuerst i am really desperate. Do you have a branch for react-native version? I can't get node-libs-react-native to integrate. Thank you

Hi @soldatos,

please have a look at FahrplanApp for an example of hafas-client with react native.

I can't provide a known-working version, sorry; react-native is not a priority for me, and setting it up is just too much of a hassle. I have googled a bit™ though:

As of version 6.0.0, hafas-client makes use of the following dependencies (this is similar with hafas-client@5) that are not self-contained environment-independent JS:

It also uses the following Node builtins:
