[Engine-devel] ovirt-engine-sdk with C

Fri Jun 7 09:47:48 UTC 2013

Hi, Jarod.W:

         Thanks for your demo, but I think you miss two fucntinos like this:

curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);

         curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);

the following new demo code on my ubuntu is work well:

#include <stdio.h>

#include <curl/curl.h>

int main(void)

{

    CURL *curl;

    CURLcode res;

    curl_global_init(CURL_GLOBAL_DEFAULT);

    curl = curl_easy_init();

    if(curl)

    {

        curl_easy_setopt(curl, CURLOPT_URL, "https://192.168.1.201/api/");

        curl_easy_setopt(curl, CURLOPT_USERPWD, "admin at internal:111111");

        curl_easy_setopt(curl, CURLOPT_CAINFO,"/tmp/ca.crt");

        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);

        curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);

        res = curl_easy_perform(curl);

        if(res != CURLE_OK)

            fprintf(stderr, "curl_easy_perform() failed: %s\n",

                    curl_easy_strerror(res));

        curl_easy_cleanup(curl);

    }

    curl_global_cleanup();

    return 0;

}

when I add this two functions , it works well for admin at internal

but can’t work for user portal, I check the information sent by 

admin at internal and user portal, the only difference is Filter,

admin at internal is Filter:False, the user portal is Filter:True.

How can I use curl_easy_setopt to set Filter .

                            Thanks

                                               Leaboy

Hi, Jarod. W:

         I got your demo, and a build libcurl, but I can’t get any info

from https://{ovirt-engine }/api .

my code like this:

Please try to run the below command:
--
curl https://YOURIP/api -u YOURNAME:YOURPASSWD --cacert /root/ca.crt
--

After, please parse the result.

ps, I run the program on centos 6.4, and it works.

thanks.

int main(void)

{

    CURL *curl;

    CURLcode res;

    curl = curl_easy_init();

    if (curl)

    {

        printf("enter....\n");

        curl_easy_setopt(curl, CURLOPT_URL, "https://192.168.1.201/api");

        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, callback_func);

        curl_easy_setopt(curl, CURLOPT_USERPWD, "admin at internal:111111");

        curl_easy_setopt(curl, CURLOPT_CAINFO,"/tmp/ca.crt");

        curl_easy_perform(curl);

        printf("exit.....\n");

        curl_easy_cleanup(curl);

    }

    return 0;

}

And when I run it, just outpu :

enter....

exit.....

I got the libcurl from http://curl.haxx.se/download.html and chosed curl-7.30.0.tar.gz <http://curl.haxx.se/download.html%20and%20chosed%20curl-7.30.0.tar.gz> 

and I use make and make install without any other options . I just guess maybe it need

other SSL library supported, but I don’t know how and which .

Hi, Jarod. W:

    Yes, I just want to use c to invoke ovirt engine RestAPI,

Just get vm’s id, host, port, secur-port, and ticket,

    How can I use libcurl to connect https, could give me

a simple demo to connect https://{ovirt-engine}/api <https://%7bovirt-engine%7d/api>  with 

--cafile, the ca.crt I get from http://{ovirt-engine}/ca.crt <http://%7bovirt-engine%7d/ca.crt> 

Please download the demo from the above url:

Hi，All

         I felt oivrt-engine-sdk coded with Python is slowly to connect

ovirt-engine and console vm when a user have many vms, So, I just

want to rewrite the sdk with C(ANSI C Language). Just rewrite a sdk

with C to connect overt-engine and console vm, would anyone give 

me some suggestion.

Do you want to use c to invoke ovirt engine RestAPI, right?

If yes, you can use libcurl to do the thing, and it'll make you happy.

         Now, the problem is how can I connect to ovit-engine with C, and

how can I get some information of vms, and how ovirrt-engine can 

respond my action(start,stop, .eg)

Agree with Michael Pasternak.

You should parse your code into the mail list, or someone can't help

you.

                                                                                    Leaboy at beijing
