Hi All,

Request your help, the below code is fetching the required data, after fetching the data at the end it throws the below errors , hence request your help on how to handle this issue.

Code:

import std.net.curl, std.stdio, std.conv: to;

void main () {
auto http = HTTP();
http.handle.set(CurlOption.userpwd, "test:password");
http.handle.set(CurlOption.connecttimeout, 300);
http.handle.set(CurlOption.timeout, 600);
http.handle.set(CurlOption.tcp_nodelay, 1);
http.handle.set(CurlOption.buffersize,1073741824);
http.handle.set(CurlOption.url, "https://test:8130/sdata";);
http.method(HTTP.Method.get);
auto content = http.perform();
http.shutdown;
foreach (line; byLine(to!string(content)))
writeln(line);
}

Error

Hi All,

I was able to resolve this issue by upgrading DMD from V88 to V91.0, and now I am getting the below error when i set any of the below options

http.handle.set(CurlOption.ipresolve, "v4");
http.handle.set(CurlOption.http_version, "v1_1");
http.handle.set(CurlOption.sslversion,  "sslv3");

Error:
std.net.curl.CurlException@std\net\curl.d(4388): A libcurl function was given a bad argument on handle CF2990

Hi All,

Was able to resolve the above issue, but need your advice as to whether i thoughts are correct.

ipresolve: The document(crul.d) for the ipresolve states the type as

enum CurlIpResolve: int;
enum CurlIpResolve {
whatever = 0, /** default, resolves addresses to all IP versions that your system allows */
  v4 = 1,       /** resolve to ipv4 addresses */
  v6 = 2        /** resolve to ipv6 addresses */
}
Solution: so I added the line "http.handle.set(CurlOption.ipresolve, 1);" for ipv4

http_version: The document(crul.d) for the http_version states the type as

enum http_version int
enum CurlHttpVersion {
    none, /** setting this means we don't care, and that we'd
             like the library to choose the best possible
             for us! */
    v1_0, /** please use HTTP 1.0 in the request */
    v1_1, /** please use HTTP 1.1 in the request */
    last  /** *ILLEGAL* http version */
}

Solution: so I added the line "http.handle.set(CurlOption.http_version, 2);" for v1_1, not sure whether this is correct as it is not mentioned just followed the same rule of ipresolve.

sslversion: The document(crul.d) for the sslversion states the type as

enum CurlSslVersion: int;
enum CurlSslVersion {
    default_version,    ///
    tlsv1,      ///
    sslv2,      ///
    sslv3,      ///
    last /** never use */
}
Solution: so I added the line "http.handle.set(CurlOption.sslversion, 4);" for sslv3, not sure whether this is correct as it is not mentioned just followed the same rule of ipresolve.
