创建Paymill回调

我正在开发一个使用rails 3.2的webapp。我正尝试为Paymill构建一个回调方法，用于捕获事务成功事件。创建Paymill回调

这是我的控制器。这非常简单，当我使用CURL或Firefox插件模拟POST请求并使用Paymill文档指出的JSON正文时，它工作正常。

不幸的是，当使用Paymills自己的测试脚本（用PHP制作）时，它会失败。

class Admin::TransactionsController < ActionController::Base 

    def create 
    transaction = Transaction.new 
    transaction.client_id = params[:event][:event_resource][:client][:id] 
    transaction.trans_id = params[:event][:event_resource][:id] 
    transaction.amount = params[:event][:event_resource][:amount] 
    transaction.currency = params[:event][:event_resource][:currency] 
    transaction.save 
    render :nothing => true 
    end 

end

这是JSON体，该文件说，它会附着在回调事件：

{ 
    "event": { 
     "event_type": "transaction.succeeded", 
     "event_resource": { 
      "id": "tran_d06aae1df72af329c39367cde9ed19", 
      "amount": "12345", 
      "origin_amount": 12345, 
      "status": "closed", 
      "description": "test paymill", 
      "livemode": false, 
      "refunds": null, 
      "currency": "USD", 
      "created_at": 1375457696, 
      "updated_at": 1375457696, 
      "response_code": 20000, 
      "short_id": null, 
      "is_fraud": false, 
      "invoices": [], 
      "app_id": null, 
      "fees": [], 
      "payment": { 
       "id": "pay_46ee3be859eedb72d325adcb6", 
       "type": "creditcard", 
       "client": "client_d94e1e3efbc59073629df", 
       "card_type": "visa", 
       "country": null, 
       "expire_month": "1", 
       "expire_year": "2014", 
       "card_holder": null, 
       "last4": "1111", 
       "created_at": 1375457695, 
       "updated_at": 1375457696, 
       "app_id": null 
      }, 
      "client": { 
       "id": "client_d941e3efbc59e073629df", 
       "email": null, 
       "description": null, 
       "created_at": 1375457696, 
       "updated_at": 1375457696, 
       "app_id": null, 
       "payment": [], 
       "subscription": null 
      }, 
      "preauthorization": null 
     } 
    } 
}

使得与PHP测试脚本的身体到达这种形状和Rails得来的错误请求当：

string(1712) ""{\n \"event\": {\n \"event_type\": \"transaction.succeeded\",\n \"event_resource\": {\n \"id\": \"tran_d06aae1f72af329c39367cde9ed19\",\n \"amount\": \"12345\",\n \"origin_amount\": 12345,\n \"status\": \"closed\",\n \"description\": \"test paymill\",\n \"livemode\": false,\n \"refunds\": null,\n \"currency\": \"USD\",\n \"created_at\": 1375457696,\n \"updated_at\": 1375457696,\n \"response_code\": 20000,\n \"short_id\": null,\n \"is_fraud\": false,\n \"invoices\": [],\n \"app_id\": null,\n \"fees\": [],\n \"payment\": {\n \"id\": \"pay_46ee3b85f9eedb72d325adcb6\",\n \"type\": \"creditcard\",\n \"client\": \"client_d941e3effbc59073629df\",\n \"card_type\": \"visa\",\n \"country\": null,\n \"expire_month\": \"1\",\n \"expire_year\": \"2014\",\n \"card_holder\": null,\n \"last4\": \"1111\",\n \"created_at\": 1375457695,\n \"updated_at\": 1375457696,\n \"app_id\": null\n },\n \"client\": {\n \"id\": \"client_d941e3efbc59073629df\",\n \"email\": null,\n \"description\": null,\n \"created_at\": 1375457696,\n \"updated_at\": 1375457696,\n \"app_id\": null,\n \"payment\": [],\n \"subscription\": null\n },\n \"preauthorization\": null\n }\n }\n}""

我Rails中得到的错误，现在是这样的：

Error occurred while parsing request parameters 

NoMethodError - undefined method `each' for #<String:0x007fc820a1fc08>:

这是怎么回事？这就像Rails把这个机构看作错误的文本一样？如果我从PHP中删除此行（因此JSON在发送之前不对其进行编码），它可以正常工作，并且不会出错。如果我的create方法是空的，那也无关紧要。这个方法被调用之前发生了什么？

json_encode($http_body);

感谢您的帮助！我很快就会开始哭泣。

你从哪里得到测试脚本？一个我这里有，确实包含以纯文本的身体，所以它不需要JSON编码了，这应该工作（与您的网址替换< YOUR_TARGET_URL>）：

<?php 
    $http_body = '{ 
     "event" : { 
      "event_type" : "transaction.succeeded", 
      "event_resource" : 
       {"id":"__TRANSACTION_ID__","amount":"12345","origin_amount":12345,"status":"closed","description":"test paymill","livemode":false,"refunds":null,"currency":"SEK","created_at":1375457696,"updated_at":1375457696,"response_code":20000,"short_id":null,"is_fraud":false,"invoices":[],"app_id":null,"fees":[],"payment":{"id":"__PAYMNET_ID__","type":"creditcard","client":"__CLIENT_ID__","card_type":"visa","country":null,"expire_month":"1","expire_year":"2014","card_holder":null,"last4":"1111","created_at":1375457695,"updated_at":1375457696,"app_id":null},"client":{"id":"__CLIENT_ID__","email":null,"description":null,"created_at":1375457696,"updated_at":1375457696,"app_id":null,"payment":[],"subscription":null},"preauthorization":null} 
     } 
    }'; 

    $curl   = curl_init(); 

    $curlOpts = array(
     CURLOPT_URL => '', 
     CURLOPT_RETURNTRANSFER => true, 
     CURLOPT_CUSTOMREQUEST => 'POST', 
     CURLOPT_SSL_VERIFYPEER => false, 
     CURLOPT_SSLVERSION  => 3, 
     CURLOPT_TIMEOUT   => 60, 
     CURLOPT_CONNECTTIMEOUT => 60, 
     CURLOPT_HTTPHEADER  => array('Content-type: application/json'), 
     CURLOPT_PROTOCOLS  => CURLPROTO_HTTP | CURLPROTO_HTTPS, 
     CURLOPT_MAXREDIRS  => 5 
    ); 

    $curlOpts[CURLOPT_URL] = '<__YOUR_TARGET_URL__>'; 
    $curlOpts[CURLOPT_POSTFIELDS] = $http_body; 
    curl_setopt_array($curl, $curlOpts); 
    $result = curl_exec($curl); 
    $responseInfo = curl_getinfo($curl); 

    var_dump($responseInfo); 
    var_dump($result); 
    curl_close($curl); 

    exit;
