如何在 Laravel 5 中处理“请求被 Throttle 服务器拒绝”SOAP 响应答案

【问题标题】：How to deal with "Request denied by Throttle server" SOAP responses in Laravel 5如何在 Laravel 5 中处理“请求被 Throttle 服务器拒绝”SOAP 响应

【问题描述】：

我制作了一个使用 SOAP 交换从 Web API 获取数据的 Web 应用程序。这最初是以程序方式完成的，我现在正试图将其移入 Laravel 框架。如果 SOAP 响应是“请求被 Throttle 服务器拒绝”，我设置了 view 以向用户显示，但我不知道如何检查该特定错误。这是课程：

<?php namespace App\Models;

use SoapClient;
use Illuminate\Http\RedirectResponse;

class SoapWrapper {

public function soapExchange() {

    // set WSDL for authentication and create new SOAP client
    $auth_url  = "http://search.webofknowledge.com/esti/wokmws/ws/WOKMWSAuthenticate?wsdl";

    // set WSDL for search and create new SOAP client
    $search_url = "http://search.webofknowledge.com/esti/wokmws/ws/WokSearch?wsdl";

    // array options are temporary and used to track request & response data
    $auth_client = @new SoapClient($auth_url);

    // array options are temporary and used to track request & response data
    $search_client = @new SoapClient($search_url);

    // run 'authenticate' method and store as variable
    $auth_response = $auth_client->authenticate();

    // call 'setCookie' method on '$search_client' storing SID (Session ID) as the response (value) given from the 'authenticate' method
    // check if an SID has been set, if not it means Throttle server has stopped the query, therefore display error message
    if (isset($auth_response->return)) {
        $search_client->__setCookie('SID',$auth_response->return);
    } else {
        return Redirect::route('throttle');
    }
}
}

问题是它在到达if 语句检查 SOAP 请求是否返回值 (SessionID) 之前，会在 $auth_response = $auth_client->authenticate(); 处引发“请求被 Throttle 服务器拒绝”默认 Laravel 错误。由于某种原因，它在以程序方式设置时并没有这样做。

if 语句检查是否已从 authenticate() 方法返回值，如果有，则将其 (SessionID) 分配给搜索客户端的 cookie 以授权搜索。否则会显示自定义错误消息。

我尝试过使用is_soap_fault，但这并没有抓住它，因为它在技术上不是肥皂故障。我还尝试删除导致问题的行并将if 语句更改为：

if (isset($auth_client->authenticate()->return) {...

但这也只会导致默认的 Laravel SoapFault 页面。 return Redirect::route('throttle') 向用户显示自定义错误页面，保存为throttle.blade.php。

有人知道如何测试油门错误吗？

没关系，在这里找到答案：Catching an exception when creating a new SoapClient properly。

无论如何我都会发布我修改后的代码，以防将来对其他人有用：

<?php namespace App\Models;

use SoapClient;
use Illuminate\Http\RedirectResponse;

class SoapWrapper {

public function soapExchange() {

    try {
        // set WSDL for authentication and create new SOAP client
        $auth_url = "http://search.webofknowledge.com/esti/wokmws/ws/WOKMWSAuthenticate?wsdl";

        // set WSDL for search and create new SOAP client
        $search_url = "http://search.webofknowledge.com/esti/wokmws/ws/WokSearch?wsdl";

        // array options are temporary and used to track request & response data
        $auth_client = @new SoapClient($auth_url);

        // array options are temporary and used to track request & response data
        $search_client = @new SoapClient($search_url);

        // run 'authenticate' method and store as variable
        $auth_response = $auth_client->authenticate();

        // add SID (SessionID) returned from authenticate() to cookie of search client
        $search_client->__setCookie('SID', $auth_response->return);

    } catch (\SoapFault $e) {
        return Redirect::route('throttle');
    }
}
}
