HL7800 KHTTPPOST, NO CARRIER, Syntax error?

timroadley · December 5, 2019, 6:40am

Hi,

I’m really close to getting a successful HTTPS POST with the HL7800.

At the final step, I’m getting a NO CARRIER / KHTTP_ERROR: 1,6, which I understand means HTTP connection timeout. I suspect this is due to the way I construct the KHTTPPOST being wrong.

The full uri I’m posting to is https://api.sandbox.ewaypayments.com/DirectPayment.json.

Can you confirm how the post should be constructed?

I was thinking AT+KHTTPPOST=1,"/DirectPayment.json",1 however that doesn’t work for some reason.

Here’s the full AT output, thanks for your continued support, it’s been great so far!

Hi,

You stored CA to module in your log file.
You need to store more Client certificate, client key to module. These certificates, keys are matched with api.sandbox.ewaypayments.com server.

You can try AT+KHTTPPOST=1, ,“/DirectPayment.json”,1" instead of AT+KHTTPPOST=1,“/DirectPayment.json”,1

timroadley · December 5, 2019, 10:34pm

Hi Donald,

I got the publicly trusted root ca for api.sandbox.ewaypayments.com from ssltools.com.

For the client cert, I’m not sure how to go about getting it since the site uses basic authentication (not cert auth). Do you have any tips on this? I mean, how would you get it for this site?

Do I need to include the intermediate certificates?

There seems to be an extra " in that suggestion, did you mean:

AT+KHTTPPOST=1,"/DirectPayment.json",1

Cheers

Donald · December 10, 2019, 9:47am

Hi,

The https://api.sandbox.ewaypayments.com/ side requires user, password to access it.
You need to fill login, password in +KHTTPCFG command
AT+KHTTPCFG=<cnx cnf>,<http_server>[,<http_port>[,<http_version>[,<login>[,<password>[,<start>[,<af>[,<cipher_index>]]]]]]]

→ No, you don’t. Only need trusted root CA.

 You can try AT+KHTTPPOST=1,,"/DirectPayment.json",1" instead of AT+KHTTPPOST=1,"/DirectPayment.json",1
AT+KHTTPPOST=<session_id>,<local_uri>,<request_uri>[,<show_resp>]
<local_uri> This argument must be empty. It is reserved for compatibility of command syntax

timroadley · December 11, 2019, 7:12am

Hi Donald,

The specific HTTPS POST I’m trying to get working is as per https://eway.io/api-v3/?shell#direct-connection

The authentication is basic
The username is 60CF3Ce97nRS1Z1Wp5m9kMmzHHEh8Rkuj31QCtVxjPWGYA9FymyqsK0Enm1P6mHJf0THbR
The password is API-P4ss

I tried your suggestion with this:

AT+KHTTPPOST=1,,"/DirectPayment.json",1"

…however I suspect there’s an extra " in there preventing it from working

I also tried this:

AT+KHTTPPOST=1,,"/DirectPayment.json",1

…however that didn’t work either.

Here’s the full AT log, which uses a http header for authentication, which is a base64 encoded Authorization: Basic NjBDRjNDZTk3blJTMVoxV3A1bTlrTW16SEhFaDhSa3VqMzFRQ3RWeGpQV0dZQTlGeW15cXNLMEVubTFQNm1ISmYwVEhiUjpBUEktUDRzcw==

Thanks for your persistence, I think we’re really close here!!!

Hi timroadley,

If you want to perform HTTPS POST to https://api.sandbox.ewaypayments.com server
It is out of order for me. Please contact eway support for server support.

timroadley · December 11, 2019, 11:30am

Hi Donald,

Hmm that’s odd, it works with Postman. Perhaps it was a temporary issue that’s ok now, can you retry?

Cheers

Donald · December 12, 2019, 11:55am

Hi,

It is same result at my side.
