Laravel 5在localhost:8000上捕获PayPal PHP API 400错误 [英] Laravel 5 catching PayPal PHP API 400 errors on localhost:8000

问题描述

在我的Laravel 5.2安装中使用PayPal API，特别是以下软件包: https://github.com /anouarabdsslm/laravel-paypalpayment

Using the PayPal API with my Laravel 5.2 install, specifically this package: https://github.com/anouarabdsslm/laravel-paypalpayment

该程序包很棒！而且我正在完美地付款！我正在努力捕捉并重定向错误的详细信息，例如银行卡详细信息由用户输入. Laravel应用程序仅引发400错误.

The package works great! and I am taking payments perfectly! I am struggling to catch and redirect when incorrect details e.g. bank card details are entered by a user. The Laravel application just throws a 400 error.

我想做的就是捕捉错误并重定向回并通知用户.

What I am wanting to do is catch the errors and redirect back and notify the user.

下面的代码是我发出请求的地方:

The code below is where I make a request:

try {
    // ### Create Payment
    // Create a payment by posting to the APIService
    // using a valid ApiContext
    // The return object contains the status;

    $payment->create($this->_apiContext);

} catch (\PPConnectionException $ex) {
    return Redirect::back()->withErrors([$ex->getMessage() . PHP_EOL]);
}

dd($payment);

成功付款后，我会得到一个不错的退货对象，可以参考并采取相应的措施，当出现类似400错误的问题时，它会完全杀死应用程序，并且不会捕获错误并将其重定向回用户.

When a successful payment is made I get a nice return object that I can reference and action accordingly, when there is an issue like a 400 error it kills the application completely and DOES NOT catch and redirect the errors back to the user.

错误代码消息是:

PayPalConnectionException in PayPalHttpConnection.php
Got Http response code 400 when accessing 
https://api.sandbox.paypal.com/v1/payments/payment.

有人在使用PayPal PHP API时遇到过类似的问题吗?

Has anyone faced similar issues with the PayPal PHP API?

我知道当应用程序不处于开发模式时，我可以拥有专门用于捕获某些错误代码的错误页面.但我真的很想抓住错误，并通过向用户发送通知将其重定向回表单.

I know when the application isn't in dev mode I can have error pages specifically to catch certain error codes. But I really want to catch errors and redirect back to the form with notifications for the user.

在此先感谢任何可以提供帮助的向导.

Thanks in advance to any wizard who can help.

推荐答案

对，

我在此处发布了答案: Laravel 5捕获了来自PayPal的400条响应API ，但是我想确保碰到这个线程的任何人都知道我是如何解决该问题的！

I posted the answer here: Laravel 5 catching 400 response from PayPal API but I want to make sure anyone hitting this thread knows how I solved the issue!

Laravel的默认Exception方法似乎正在干扰PayPal API PayPalConnectionException.因此，我修改了代码以仅捕获常规Exception错误，因为它包含所有必需的错误对象. Exception之前的\至关重要！因为它需要正确的名称空间(就我而言，您的应用程序可能有所不同).

It would appear that Laravel's default Exception method was interfering with the PayPal API PayPalConnectionException. So I modified the code to catch general Exception errors only as it contained all required error objects. The \ before Exception was critical! as it needs the correct namespace (in my case anyway, your application may be different).

try {
    // ### Create Payment
    // Create a payment by posting to the APIService
    // using a valid ApiContext
    // The return object contains the status;
    $payment->create($this->_apiContext);

} catch (\Exception $ex) {
    return Redirect::back()->withErrors([$ex->getData()])->withInput(Input::all());
}

此链接非常有用，一旦我正确地命名了所有名称空间，应用程序似乎总是会遇到\Exception而不是\PayPalConnectionException的问题.

This link that @rchatburn posted was highly useful, the application always seemed to catch at the point \Exception and NOT \PayPalConnectionException once I had everything namespaced correctly.

在调查中，我遇到了app/Exceptions/Handler.php.在这里，您可以扩展render方法以获取PayPalConnectionException，并针对该特定异常唯一地处理错误.查看代码:

In my investigations I came across app/Exceptions/Handler.php. Here you can extend the render method to grab a PayPalConnectionException and handle the errors uniquely to that specific exception . See code:

//Be sure to include the exception you want at the top of the file
use PayPal\Exception\PayPalConnectionException;//pull in paypal error exception to work with

public function render($request, Exception $e)
{
    //check the specific exception
    if ($e instanceof PayPalConnectionException) {
        //return with errors and with at the form data
        return Redirect::back()->withErrors($e->getData())->withInput(Input::all());
    }

    return parent::render($request, $e);
} 

这两种方法都很好，但是对我来说，将catch方法更改为监视一般Exception的想法让我感到很整洁，我在这里测试付款是否成功.

Either work great, but for me it felt neater to just change the catch method to a lookout for a general Exception, where I am testing if a payment was successful.

希望这可以帮助面临类似问题的任何人:D !!!

Hope this helps anyone facing similar issues :D!!!
