HTTP POST Request and JSON Processing

The script uses `PROC HTTP` to send encoded data (custname, size, topping) via a POST request to the `/post` endpoint of `httpbin.org`. The JSON response from the web service is stored in a temporary file. A `DATA _NULL_` step then uses the `jsonpp` function to parse and format the JSON content of this response, displaying it legibly in the SAS^© log.

Data Analysis

Type : GENERATION_INTERNE_ET_EXTERNE

The body of the POST request is defined internally within the script. The response (JSON data) is received from an external web service (`httpbin.org`).

1 Code Block

PROC HTTP Data

Explanation :
This block establishes an HTTP connection and sends a POST request with specific parameters to the target URL. The server's response is captured and written to a temporary file named 'resp'.

1	filename resp temp;
2	PROC HTTP
3	url="http://httpbin.org/post"
4	method="POST"
5	in="custname=Joe%str(&)size=large%str(&)topping=cheese"
6	out=resp;
7	RUN;

DATA STEP

Explanation :
This `DATA _NULL_` block uses the `jsonpp` function to read the JSON content from the temporary file 'resp' and format it neatly in the SAS log, making it easier to read and examine.

Copied!

1	DATA _null_;
2	rc = jsonpp('resp','log');
3	RUN;
