帶有PostgreSQL數據庫的Dancer2應用

Question

我正在嘗試在Dancer2中集成一個小的PostgreSQL數據庫。...部署架構后，我在app.pm文件中使用了該數據庫以連接到架構：

my $schema = My::Schema->connect("dbi:Pg:dbname=mytestdb;host=localhost;port=5432;","test","test");

當我啟動我的應用程序時，我可以使用以下請求創建一個新用戶（已插入數據庫）：

post '/register' => sub {


    my $username = params->{username};
    my $fullname = params->{fullname};
    my $password = params->{password};
    warn "The pass is |$password|\n";


        my $saved_pass = &crypt_password($password);   



    $schema->resultset('User')->create({
        username => $username, 
        fullname => $fullname,
        password => $saved_pass,

    }); 

    redirect '/';

};

但是當我嘗試使用此登錄時：

post '/login' => sub {
    my $username  = params->{username};
    my $password  = params->{password}; 



     my $user = $schema->resultset('User')->search({ username => $username })->first;       




        my ($success, $realm) = authenticate_user(
            $username, $password
        );


        if ($success) {
            session logged_in_user => $success;
            session logged_in_user_realm => $realm;
            session user => $user;



        } else {
             authentication failed
        }       



};

我的應用程序因以下錯誤DBIx::Class::Storage::DBI::catch {...} (): DBI Connection failed: DBI connect('dbname=mytestdb','test',...) failed: FATAL: Peer authentication failed for user "test" ： DBIx::Class::Storage::DBI::catch {...} (): DBI Connection failed: DBI connect('dbname=mytestdb','test',...) failed: FATAL: Peer authentication failed for user "test" 。

Answer 1

我通過添加以下行在/etc/postgresql/9.3/main/pg_hba.conf中編輯了pg_hba.conf文件：

    # IPv4 local connections:
    host    all         all         127.0.0.1/32          md5
    local   all         all                               trust

經過這些修改，我的應用程序登錄了。
