RCurl post request implement problem.

Hi All,
I want to post request for getting data from API  via RCurl.

in Linux command line, I do it successfully:

 dt = 'date+%y%m%d%H%M%S'
 home_ph = /data/test
 data_ph = /data/test/data
 urls = 183.60.7.39:9980
 curl $urls -H 'Connection: close' -o $data_ph/$1-$2-$dt.txt -u user1:eb2e9a27392d4cfd3ce2d3f00bc18d7e --data @$home_ph/$1 --compressed

the post content as follows:

 <?xml version="1.0" encoding="UTF-8"?>

 <kangaroo-request>

 <request>

 <sqlId>test_2</sqlId>

 <content-type>text/json</content-type>

 <startRow></startRow>

 <endRow></endRow>

 <alias>gds</alias>

 <params></params>

 </request>

 </kangaroo-request>



But I cannot code it with getURL() function in R.

  >> sort(names(getCurlOptionsConstants()))

Although I can get the list of options, No further info about these options,

no bridge between the options of getURL() and libCurl.


Could anyone give me some advice for me to do the code with RCurl Library in R ?

Any help is much appreciated. 3x much.
