6.4.2 Use Cases in Synchronous Mode with +SQNHTTP Commands

6.4.2.1 Send a GET Request
Command
Type this command to configure the HTTP connection without SSL enabled.
AT+SQNHTTPCFG=1,"httpbin.org",80,0,"","",0,120,1
AT+SQNHTTPCFG?
AT+SQNHTTPQRY=1,0,"/"
If succeed before timeout, you would get an URC. This means the file is found and length is 13011.
AT+SQNHTTPRCV=1,0
Then would get the file shown on the screen. This is ended by an "OK" in the last line.
6.4.2.2 Send POST Request with AT+SQNHTTPSND
This test is to be run after the GET request sequence.
Command
AT+SQNHTTPSND=1,0,"/post",7
Type string with additional parameter and press CTRL+Z
foo=bar
AT+SQNHTTPRCV=1,0
You would get the data, followed by an "OK" in a separated line.
6.4.2.3 Note on <post_param> and <extra-header-line> Parameter
In AT+SQNHTTPSND, the parameter <post_param> is optional. It is to be used only for POST request type
and is related to <Content-Type> in the HTTP header. In the example above, "0" default value is used.
HTTP packets include, in the header:
Content-Type: application/x-www-form-urlencoded
You might want to define charset for text/plain, or boundary for multipart/form-data. In these
cases, you need an extension as detailed below:
•
Set charset to us-ascii:
Set <post_param> to "1:charset=us-ascii", then the request will contain "Content-type: text/plain;
charset=us-ascii" header line.
AT+SQNHTTPSND=1,0,"/post",7,"1:charset=us-ascii"
•
Set boundary "—-WebKitFormBoundaryv9K2Q6NJOnI5kAZX"
