Question

参考下面的代码，我从here获得，结果部分（第40行以后）将采用字符串格式。如何将其更改为JSON？到目前为止，我知道我需要包含JSON::Create。在那之后，我不确定如何继续。

use Net::Google::Analytics;
use Net::Google::Analytics::OAuth2;

# Insert your numeric Analytics profile ID here. You can find it under
# profile settings. DO NOT use your account or property ID (UA-nnnnnn).
my $profile_id    = "1234567";

# See GETTING STARTED for how to get a client id, client secret, and
# refresh token
my $client_id     = "123456789012.apps.googleusercontent.com";
my $client_secret = "rAnDoMsEcReTrAnDoMsEcReT";
my $refresh_token = "RaNdOmSeCrEtRaNdOmSeCrEt";

my $analytics = Net::Google::Analytics->new;

# Authenticate
my $oauth = Net::Google::Analytics::OAuth2->new(
    client_id     => $client_id,
    client_secret => $client_secret,
);
my $token = $oauth->refresh_access_token($refresh_token);
$analytics->token($token);

# Build request
my $req = $analytics->new_request(
    ids         => "ga:$profile_id",
    dimensions  => "ga:medium,ga:source",
    metrics     => "ga:bounces,ga:visits",
    filters     => "ga:medium==referral",
    sort        => "-ga:visits",
    start_date  => "2011-10-01",
    end_date    => "2011-10-31",
    max_results => 5,
);

# Send request
my $res = $analytics->retrieve($req);
die("GA error: " . $res->error_message) if !$res->is_success;

# Print results

print
    "Results: 1 - ", $res->num_rows,
    " of ", $res->total_results, "\n\n";

for my $row (@{ $res->rows }) {
    print
        $row->get_source,  ": ",
        $row->get_visits,  " visits, ",
        $row->get_bounces, " bounces\n";
}

print
    "\nTotal: ",
    $res->totals("visits"),  " visits, ",
    $res->totals("bounces"), " bounces\n";

修改

我已经从# Print results开始编辑了我的代码：

# Print results

print
  "Results: 1 - ", $res -> num_rows,
  " of ", $res -> total_results, "\n\n";

for my $row(@{
  $res -> rows
}) {
  %hash = ("source:" => $row -> get_source, "visits:" => $row -> get_visits, "bounces:" => $row -> get_bounces, "sessions:" => $row -> get_sessions, "users:" => $row -> get_users);

  print create_json (\%hash);
  print ("\n");
}

我的输出最终是JSON格式：

{"source:":"pinterest.com","visits:":"17497","sessions:":"17497","bounces:":"13625","users:":"17882"} {"visits:":"6223","sessions:":"6223","source:":"m.facebook.com","bounces:":"4693","users:":"6298"} {"visits:":"2612","sessions:":"2612","source:":"pinterest.com","bounces:":"1945","users:":"1766"} {"users:":"933","source:":"m.facebook.com","sessions:":"1671","visits:":"1671","bounces:":"1334"} {"users:":"422","bounces:":"728","visits:":"1125","sessions:":"1125","source:":"disq.us"}

如何以JSON格式输出此Perl脚本？
