Json Interface

[Carlo Vignapiano]

I'm a programmer and I'm looking for interfacing with the BlueIris Json Interface. I want running the Login (JAVASCRIPT POST COMMAND) command, I can not get the session variable needed to access. Can anyone tell me something about it?

Hi, I'm a programmer too. You may want to try/check out this code: https://github.com/magapp/blueiriscmd/blob/master/blueiris.py.

Basically, you request a "session response" by logging onto the BI webserver with your user and password values. You save that "session response" and use it for other commands.

Personally, I think the BI json interface needs a *lot* more functionality added to it. I have a need to change Trigger settings at random times, but that's just me...

I tried everything but always answers me {login:'fail'} without the session variable. I tried Jquery ajax, Vue http-request, Rest Api Chrome Extension, but nothig anything.
My url is http://vdsserv.synology.me:8080/json,

Do I have to change something on the program?

If you inspect the source of Blue Iris's login page(function login), that page uses the json API to log in.

Basically you just send an empty login command:

POST http://192.168.0.166:81/json HTTP/1.1
Host: 192.168.0.166:81
Connection: keep-alive
Content-Length: 15
Accept: application/json, text/javascript, */*; q=0.01
Origin: http://192.168.0.166:81
X-Requested-With: XMLHttpRequest
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36
Content-Type: text/plain
Referer: http://192.168.0.166:81/login.htm?page=%2Fui3.htm
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.9

{"cmd":"login"}

The response contains a new session ID for you, and indicates that you need to generate a "response" field containing the hashed credentials.

HTTP/1.1 200 OK
Server: BlueIris-HTTP/1.1

Content-Length: 118

{"result":"fail","session":"19713c7d023d4da103c41c95501d22e6","data":{"auth-exempt":true,"reason":"missing response"}}

(note in this case the "auth-exempt":true indicates that anonymous access is enabled)

Anyway you respond to that as outlined in the JSON API documentation.

POST http://192.168.0.166:81/json HTTP/1.1

And BI should respond with success if it worked:

HTTP/1.1 200 OK

{"result":"success","session":"19713c7d023d4da103c41c95501d22e6","data":{…}}

I created a simple example, if you check the chrome console, section xhr (http://vdsserv.synology.me/blueiris/), in onload page the call always responds to me fail, without the session variable, something in the call I have to add as a configuration , I think. What do you recommend?

I solved I used the XMLHttpRequest, Vue Post is evidently not a correct post, thank you very much for your help
