集成wepay SDK库与codeigniter2.2配合使用

问题描述 投票:0回答:1

我正在使用 codeigniter 2.2 处理应用程序,但现在我遇到了将 wepay 库 wepay.php 集成到 codeigniter 库中的问题。如有任何帮助,我们将不胜感激 这是 wepay 提供的当前库。 我尝试将 wepay.php 集成到 codeigniter 中,但它显示白屏。我认为 wepay.php 中定义的多个类存在问题,我不知道如何在 codeigniter 中处理这个问题

打开account.php文件:

    <?php
require './_shared.php';
?>
<h1>WePay Demo App: Open Account</h1>
<a href="index.php">Back</a>
<br />

<?php 

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    if (isset($_POST['account_name']) && isset($_POST['account_description'])) {
        // WePay sanitizes its own data, but displaying raw POST data on your own site is a XSS security hole.
        $name = htmlentities($_POST['account_name']);
        $desc = htmlentities($_POST['account_description']);
        try {
            $wepay = new WePay('STAGE_5cdbb3fa32af0ccaef97328542d5e2a0a7f61263ed2bcd79c9f29c2d5e0d85e6');
            $account = $wepay->request('account/create', array(
                'name' => $name,
                'description' => $desc,
            ));
            echo "Created account $name for '$desc'! View on WePay at <a href=\"$account->account_uri\">$account->account_uri</a>. See all of your accounts <a href=\"accountlist.php\">here</a>.";
        }
        catch (WePayException $e) {
            // Something went wrong - normally you would log
            // this and give your user a more informative message
            echo $e->getMessage();
        }
    }
    else {
        echo 'Account name and description are both required.';
    }
}
?>

<form method="post">
    <fieldset>
        <legend>Account Info</legend>

        <label for="account_name">Account Name:</label><br />
        <input type="text" id="account_name" name="account_name" placeholder="Ski Trip Savings"/>

        <br /><br />

        <label for="account_description">Account Description: </label><br />
        <textarea name="account_description" rows="10" cols="40" placeholder="Saving up some dough for our ski trip!"></textarea>

        <br /><br />

        <input type="submit" value="Open account" />
    </fieldset>
</form>

shared.php 文件:

    <?php
require '../wepay.php';
Wepay::useStaging('34218', '7c09762bbe','2014-01-08');
session_start();
    ?>

请看一下 wepay.php 的底部,它是在一个类中定义了多个类。

这里是在codeigniter中集成wepay库的解决方案

转到 application/config/config.php 并在末尾添加以下 wepay 应用凭据 config.php 你也可以制作单独的配置文件,但我已将其包含在 CI 的配置中

/*WEPAY config items*/
$config['client_id']='client_id_here';
$config['client_secret']='client_secret_here';
$config['app_version']='2014-01-08'; // this could be different in future
$config['access_token']='access_token_here';
/* End of file config.php */
/* Location: ./application/config/config.php */

在 Codeigniter 的 application/libraries/wepay.php 中创建一个文件名 wepay.php 并将以下内容粘贴到 wepay.php 中的第 202 行添加您的应用程序的访问令牌,并记住在上线时删除 wepay.php 的第 234 行,我添加了这行代码来阻止curl 验证SSL 证书。

curl_setopt(self::$ch, CURLOPT_SSL_VERIFYPEER, 0);

现在最后一步制作一个控制器,这里我的控制器名称是 payment 这是它的内容: 应用程序/控制器/ payment.php

之后您可以通过在浏览器 localhost/yourapplication/index.php/ payment/test_wepay_response 中添加控制器名称和方法来调用控制器方法

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Payment extends CI_Controller {
public function __construct()
    {
        parent::__construct();
        if($this->session->userdata('urole') != 'admin'){redirect('admin_login');}

        $this->load->library('wePay','wepay');
        $this->load->model('admin_model','admin');
    }

    public function index()
    {   echo 'Hi there library loaded';exit;

    }

    public function test_wepay_response()
    {   
$client_id=$this->config->item('client_id');
$client_secret= $this->config->item('client_secret'); 
$client_secret= $this->config->item('app_version');


$this->wepay->useStaging($client_id,$client_secret,$app_version);
        //$data = array('account_id' => '12345');
        $response =$this->wepay->request('account/find');
        print_r($response);exit;
        }
