Re: std.net.curl and HTTP.responseHeaders
Thank you! For other sites, the first solution somehow worked (I did it following the example from the documentation).

Perhaps some special HTTP configuration is needed?
Is this closer to what you want?
import std.stdio, std.net.curl;
void main() {
enum url = "https://en.wikipedia.org/wiki/Passenger_pigeon;;
auto http = HTTP(url);
http.perform();

In fact, you don't need url in there either since it's not
dependent on loop variables, and you don't need the scope
guards if this is running in main (you can move them out of
the loop too).
foreach (...) {
https.handle.set(CurlOption.url, url);
https.perform();
apidata.insert(tuple(seq, cast(string) content));
content = [];
}
In fact he does not need foreach. Because he use it on empty
result
Hi All,
The reason that the above code is within foreach loop is
because there are several api's and each of the api's have
separate configuration. These configuration are maintained in a
table in MySQL database, the result contains the configuration
details for each of these api's, below is the complete code.
Sequence
The code collects the data from several api's whose output is
json.
The output of the api's are parsed, filtered, validated and
stored in a array using another function.(using asdf json parser)
The data stores in array is then inserted into the table in MySQL
database.(using hunt-database).
Code:
auto getData ()
{
Array!(Tuple!(int,string)) apidata;
Row[] result;
result = getApiconf(); \\ fetch's the api configuration
from the database table.
foreach(i, k; parallel(result,1))
{
string apihost = result[i][0].get!(string);
int apiport = result[i][1].get!(int);
string apiuser = result[i][2].get!(string);
string apipass = result[i][3].get!(string);
int seq = result[i][4].get!int;
string apiuri = result[i][5].get!(string);
int connecttimeout = result[i][6].get!(int);
int tcp_nodelay = result[i][7].get!(int);
int http_version = result[i][8].get!(int);
int sslversion = result[i][9].get!(int);
int use_ssl = result[i][10].get!(int);
int ssl_verifypeer = result[i][11].get!(int);
string url = chain(apihost, only(':'), to!string(apiport),
apiuri).to!string;
string usrpass = chain(apiuser, only(':'),
apipass).to!string;
auto https = HTTP();
https.handle.set(CurlOption.buffersize, 512000);
https.handle.set(CurlOption.userpwd, usrpass);
https.handle.set(CurlOption.connecttimeout, connecttimeout);
https.handle.set(CurlOption.tcp_nodelay, tcp_nodelay);
https.handle.set(CurlOption.http_version, http_version);
https.handle.set(CurlOption.sslversion, sslversion);
https.handle.set(CurlOption.use_ssl, use_ssl);

As far as I remember:
foreach (key, value; jv.object.byKeyValue)
byKeyValue is a function of an associative array. You get the
associative array (Json object) of an JSONValue by attribute
.object.

Still, the all-platforms zip, which is the first download option (and so I happily grabbed it), seems to contain neither libcurl nor sufficient documentation on how to install it.

Do you know what the libcurl library is actually called on your system? (try find /usr -name *curl*.so* or find /usr -name *curl*.a* ) if the name you find is e.g. libcurl3.so then you'll have to use the linker flag -lcurl3 instead of lcurl p.s.
