All requests are crashing

[baptistesola2]

• trainline version: 0.1.0
• Python version: 3.7
• Operating System: macOS

Description

All requests return the same error:
requests.exceptions.ConnectionError: Status code 400 for url https://www.trainline.eu/api/v5_1/search
{"error":{"code":"no_results","message":{}}}

What I Did

It used to work very well, but for the last few days, no requests I've tried have seem to work.
I tried to use both the trainline_cli.py file and the Docker Image (downloaded today November 24th)

trainline --departure="Toulouse" --arrival="Nantes" --next=12hours
trainline --departure="Bordeaux" --arrival="Lille" --next=12hours

Complete Traceback :

[tducret]

Same here. It seems that the version of the user agent is checked, and the one embedded in this Python package is too old.
Updating it to CaptainTrain/1574360965(web) (Ember 3.5.1) fixes the problem.
I'm going to release it in the next minutes.
Thanks @baptistesola2

[tducret]

@baptistesola2 I think it's okay now. Could you please upgrade to v0.1.1 and test it?
Python package : pip install -U trainline
Docker image: trainline --upgrade

trainline --departure="Toulouse" --arrival="Nantes" --next=12hours

Waiting for you reply to close the issue.

I still have the error 400 using pip module.

[py29]

Hi
I have the same issue. Still 400

[baptistesola2]

Hi @tducret . Yes both the package and the docker image are working for me now !
Thanks so much for your amazing reactivity !

[tducret]

@py29 and @antoinevth Could you make sure that you have version 0.1.1of the module?
pip freeze | grep trainline

[antoinevth]

Yes I did the update : pip3 freeze | grep trainline returns trainline==0.1.1
And python3 trainline_cli.py --departure="Paris" --arrival="Nantes" --next=12hours returns :

Hi,
I have the same problem since two days.
I heard on the TGVMAX Facebook group that Trainline is changing his mobile App.
Maybe they are changing their API also ?
Every request that I try with Postman on https://www.trainline.eu/api/v5_1/search ended with a 400 error...

[benoitdemaegdt]

Hi,
I also call Trainline API to detect available TGVmax travels.
Few days ago, my API calls got rejected. Changing the user agent to CaptainTrain/1574360965(web) (Ember 3.5.1) as mentioned by @tducret solved the issue.

But since the 27/11/2019, my API calls are once again being rejected.
The reason :

{"errors":{"passengers":["Veuillez creer un compte pour reserver vos voyages TGVMax"]}}

As you said @yann120 , Trainline changed their API. I'll try to dig this issue later, I'll come back here if I find something helpful 😄

[benoitdemaegdt]

Hi,
As I said yesterday, Trainline changed it's API and you now need an account if you want to book a TGVmax ticket.

Here is a quick recap of the changes :
OLD API

headers = {
 'Accept': 'application/json',
 'User-Agent': 'CaptainTrain/5221(d109181b0) (iPhone8,4; iOS 13.1.2; Scale/2.00)',
 'Accept-Language': 'fr',
 'Content-Type': 'application/json; charset=UTF-8',
 'Host': 'www.trainline.eu',
}

body = {
 "local_currency": "EUR",
 "search": {
 "passengers": [
 {
 age: 25,
 id: 'ccddfbfd-d7f5-43bf-8b64-bd92aaaf116e', # random id
 label: 'abe09e23-2d9e-4a4b-a9e3-3318e1caaf6b', # random label
 cards: [{
 reference: 'SNCF.HappyCard',
 number: '<YOUR_TGVMAX_NUMBER>'
 }],
 }
 ],
 "departure_station_id":<DEPARTURE_STATION_ID>,
 "arrival_station_id":<ARRIVAL_STATION_ID>,
 "departure_date": <DATE>,
 "systems": [
 "sncf",
 ]
 }
}

NEW API

headers = {
 'Accept': 'application/json',
 'User-Agent': 'CaptainTrain/5221(d109181b0) (iPhone8,4; iOS 13.1.2; Scale/2.00)',
 'Accept-Language': 'fr',
 'Content-Type': 'application/json; charset=UTF-8',
 'Host': 'www.trainline.eu',
 'authorization': 'Token token="<YOUR_TOKEN>"',
}

body = {
 "local_currency": "EUR",
 "search": {
 "passenger_ids": [
 "<YOUR_PASSENGER_ID>"
 ],
 "card_ids": [
 "<YOUR_CARD_ID>"
 ],
 "departure_station_id":<DEPARTURE_STATION_ID>,
 "arrival_station_id":<ARRIVAL_STATION_ID>,
 "departure_date": <DATE>,
 "systems": [
 "sncf",
 ]
 }
}

3 things changed :

• you need an authorization header
• you need a passenger id in the request body
• you need a card id in the request body

I hope it can help ...

[clairbaptiste]

how can we get authorization header ?

[antoinevth]

I just tried again today. I don't have the 400 error any more.
Regarding TGVmax, I think it's not linked to the original issue.
Maybe we should close this one and open another one to find solutions for TGVmax?
