HTTP GET Request with Basic Authentication and JSON Processing

The script uses the `PROC HTTP` procedure to initiate a GET request to the endpoint `http://httpbin.org/basic-auth/chris/pass125`. It configures basic authentication with username 'chris' and password 'pass125'. The API response is saved to a temporary file ('fileref resp'). Subsequently, a `DATA _NULL_` step uses the `JSONPP` function to parse and format the JSON content of the response, displaying the result in the SAS^© log. This allows interaction with external web services and visualization of their structured responses.

Data Analysis

Type : EXTERNE

The data processed by the script comes from an external source, specifically the URL `http://httpbin.org/basic-auth/chris/pass125`, via an HTTP GET request.

1 Code Block

PROC HTTP Data

Explanation :
This block initializes a temporary fileref named 'resp' to store the output of the HTTP request. The `PROC HTTP` procedure is then used to send a GET request to the specified URL, including basic authentication with the provided credentials. The JSON response from the server is saved to the file associated with the 'resp' fileref.

DATA STEP

Explanation :
This `DATA _NULL_` step does not create a permanent SAS dataset. It uses the `JSONPP` function to read the JSON content from the 'resp' file (the `PROC HTTP` response) and format it for readability, displaying the result directly in the SAS log. This allows for easy inspection of the JSON response's structure and content.
