I was fighting with it a little bit and after all i just leave
original function which was in code, removed dependencies from
vibe.d and finally tried to contact api. Here is my present code:
#!/usr/bin/rdmd -L-lcurl
import std.stdio;
import std.string;
import std.file;
import std.datetime;
import std.process;
import std.digest.sha;
import std.net.curl;
import sigv4;
auto zone = "us-east-1";
auto service = "ec2";
void main()
{
auto accKey = environment["AWS_ACCESS_KEY"];
auto secKey = environment["AWS_SECRET_KEY"];
auto currentClock = Clock.currTime;
auto currentDate = cast(Date)currentClock;
auto curDateStr = currentDate.toISOString;
auto currentTime = cast(TimeOfDay)currentClock;
auto curTimeStr = currentTime.toISOString;
auto xamztime = curDateStr ~ "T" ~ curTimeStr ~ "Z";
string[string] empty;
SignableRequest r;
r.dateString = curDateStr;
r.timeStringUTC = curTimeStr;
r.region = zone;
r.service = service;
r.canonicalRequest = CanonicalRequest(
"GET",
"/",
["action" : "DescribeInstances", "version" :
"2013-10-15"],
["content-type" : "application/x-www-form-urlencoded;
charset=utf-8",
"host" : service ~ ".amazonaws.com",
"x-amz-date" : xamztime],
cast(ubyte[])"");
auto qParm =
canonicalQueryString(r.canonicalRequest.queryParameters);
auto sigHead = canonicalHeaders(r.canonicalRequest.headers);
auto sigStr = signableString(r);
auto sigKey = signingKey(secKey, curDateStr, zone, service);
auto signature = sign(sigKey,
cast(ubyte[])sigStr).toHexString().toLower();
writeln();
writeln(qParm);
writeln();
writeln(sigHead);
writeln();
writeln(sigStr);
writeln();
writeln(signature);
writeln();
auto client = HTTP();
client.clearRequestHeaders;
client.addRequestHeader("content-type:",
"application/x-www-form-urlencoded; charset=utf-8");
client.addRequestHeader("host:", service ~ ".amazonaws.com");
client.addRequestHeader("x-amz-date:", xamztime);
client.addRequestHeader("Authoryzation:", "AWS4-HMAC-SHA256" ~ "
" ~ "Credential=" ~ accKey ~ "/" ~ xamztime ~ "/" ~ zone ~ "/" ~
service ~ "/" ~ "aws4_request" ~ ", " ~ "SignedHeaders=" ~
"content-type;host;x-amz-date" ~ ", " ~ "Signature=" ~ signature);
auto url = service ~ ".amazonaws.com?" ~
"Action=DescribeInstances&Version=2013-10-15";
writeln(url);
auto content = get(url, client);
writeln(content);
}
Everything is compiling but im getting 400 (Bad Request):
