Hi All,
I am new to quectel and i bought quectel EC20 EVB.
In my application i am using HTTP and i need to send data in JSON format.
But i cannot find any way to set Content-Type as application/json.
If you know how to set application/json please guide me.
In document only four method is available to set content type.
If content-type = application/json is possible then please explain that steps.
Thanks,
Hardik

AND I AM GETTING A RESPONSE LIKE THIS
Bad RequestHTTP Error 400. The request has an invalid header name.
I think you missed one line between header and body content.
Best Regards,
Hi ismail_mirsa,
send Payload ::
https://ntiiippretail.com/fold/devicereg
Hope your Full URL is like this only .if any change in Path please replace that path in Payload.
And after Content-Type you need to give one line Extra between you header and Body. Content-Type:application/json\r\n**\r\n**
Regards,
Hardik
thanks willie yao…it helped
thanks hardik…
you were right i tried with that extra line which i missed and i was able to rectify invalid header error.
but an error indicating invalid host name occured afterwards .
so i changed the host name starting from https to www
and it worked .
status : true
THANKS FOR THE HELP.
I have successfully posted the JSON data. Now the next challenge is how to parse the JSON data.
after calling AT+QHTTPGET=80 AND Then AT+QHTTPREAD=80;
PLEASE help
Hi Bhavish_yadav:
You are welcome. GET request cannot carry content.It can only request content from the server.
After you execute get successfully, you can directly read the content requested from the server through AT+QHTTPREAD=80.
Hello, I’m currently working with EC200U for HTTP GET and POST requests. I’m unsure why it’s displaying bad requests when using AT commands, but I’m able to successfully work with it using Postman software.
