The HTTP Procedure

Example 2: A POST Through a Proxy

This example makes a POST method call to an external server and, therefore, requires the use of a proxy server. Parameters to the POST are read from ProxyTest_in and the response is written to ProxyTest_out.txt.

filename in "u:\prochttp\Testware\ProxyTest_in";  
filename out "u:\prochttp\Testware\ProxyTest_out.txt";  
data _null_;     
   file in; 
   input; 
   put _infile_;      
   datalines4;  
appid=restbook&query=jellyfish

proc http       
   in=in        
   out=out       
   url="http://api.search.yahoo.com/WebSearchService/V1/webSearch?"  
   method="post"      
   ct="application/x-www-form-urlencoded"       
   proxyhost="proxygw.abc.sas.com"
