Hello,

I am completely new to the cURL. I am trying to integrate Apache Solr with c
client.

However I am trying to post http request through c client as following.
How ever I am not getting expected reply from the cURL.

but when I execute same thing through command promt it works fine.

 curl "
http://localhost:8983/solr/update/extract?literal.id=doc1&uprefix=attr_&fmap.content=attr_content&fmap.div=foo_t&boost.foo_t=3&literal.tcent_dataItemOBID=vbofJekpni6w5pdmm70a-buSsuper%20usersuWLocdoc1.pdf&commit=true""
-F "myfile=@D:/fs/2007_MP6/suWLoc/doc1.pdf"

Can any one help to find what is the exact problem in my code?

int indexInSolr()
{
   status dstat = OKAY;
   CURL *curl;
   CURLcode res;

   curl = curl_easy_init();
   if(curl)
   {
      struct solrString s;
      init_string(&s);

      //curl_easy_setopt(curl, CURLOPT_URL, cURLString);
     curl_easy_setopt(curl, CURLOPT_URL, "
http://localhost:8983/solr/update/extract?literal.id=doc1&uprefix=attr_&fmap.content=attr_content&fmap.div=foo_t&boost.foo_t=3&literal.tcent_dataItemOBID=vbofJekpni6w5pdmm70a-buSsuper%20usersuWLocdoc1.pdf&commit=true\"\"
-F \"myfile=@D:\\fs\\2007_MP6\\suWLoc\\doc1.pdf");

      curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, writefunc);
      curl_easy_setopt(curl, CURLOPT_WRITEDATA, &s);
      res = curl_easy_perform(curl);
      printf("\nPrinting value written in solrString \n%s\n", s.ptr);
      printf("\nPrinting res in solrString \n%d\n", res);
      free(s.ptr);

      /* always cleanup */
      curl_easy_cleanup(curl);
 return 0;
  };

struct solrString {
  char *ptr;
  size_t len;
};

void init_string(struct solrString *s) {
  s->len = 0;
  s->ptr = malloc(s->len+1);
  if (s->ptr == NULL) {
    fprintf(stderr, "malloc() failed\n");
    exit(EXIT_FAILURE);
  }
  s->ptr[0] = '\0';
};

size_t writefunc(void *ptr, size_t size, size_t nmemb, struct solrString *s)
{

  int input;
  size_t new_len = s->len + size*nmemb;
  //scanf("Please enter input for call bak function \n%d",&input);
  s->ptr = realloc(s->ptr, new_len+1);

  if (s->ptr == NULL) {
    fprintf(stderr, "realloc() failed\n");
    exit(EXIT_FAILURE);
  }
  memcpy(s->ptr+s->len, ptr, size*nmemb);
  s->ptr[new_len] = '\0';
  s->len = new_len;
  return size*nmemb;
};

Thanks and Regards,
Prasad
