将C#转换为PHP

Question

我正在使用SOAP和PHP访问一个Web服务。我可以通过Web服务API连接到多个函数，但有一个我无法连接。我有一个示例，但它是用C#编写的。

我尝试用PHP模仿示例，但没有成功。

我附上了C#代码和我在PHP中的尝试。还包括错误消息。

C#代码

 public void MakeSale()
 {
     string yourKey = "your key";
     using(DdDSaleService.SaleServiceClient client = new SaleServiceClient())
     {
         Sale sale = client.StartSale();
         //header info
         sale.ClientNumber = 996001;
         sale.Date = DateTime.Now;
         sale.Employee = 1;
         sale.NoteID = 123;
         sale.Terminal = 1;
         sale.Type = SaleType.Sale;

         //items in basket.
         ItemLine line1 = new ItemLine();
         line1.Type = ItemLineType.Sale;
         line1.ItemGroup = 1;
         line1.Supplier = 1;
         line1.Qty = 3;  //should -3 if a return of goods.
         line1.LineAmount = 600;  //The normal amount of the goods.
         line1.EDBNumber = 1; //unique key in our system. You have this if you got the articles by our service.
         line1.DiscountAmount = -100;  //the discount.

         //line2 comes here....

         //add the lines to the sale
         sale.ItemLines = new ItemLine[] { line1 };

         //The payment lines
         //1 with cash, and one with the change. the sale MUST sum to zero (itemlines + paymentlines)
         PaymentLine cash = new PaymentLine();
         cash.Type = PaymentLineType.Cash;
         cash.Qty = 1;
         cash.LineAmount = 600;

         PaymentLine change = new PaymentLine();
         change.Type = PaymentLineType.Change;
         change.Qty = 1;
         change.LineAmount = -100;

         //add the paymentlines
         sale.PaymentLines = new PaymentLine[]{cash,change};

         //submit the sale.
         Status response = client.SaveSale(sale, yourKey);
         Console.WriteLine(string.Format("got response from save sale saved: {0}, message: {1}",response.Saved,response.Message));
         Console.ReadLine();
    }
}

PHP代码

$client = new SoapClient("http://xxx.xxxxx.xxxx/xxxxxxx.svc?wsdl", array("trace" => 1, "connection_timeout" => 500));

// Initialize sale
// $client is a valid SOAP connection
// That has been setup earlier
$Sale = $client->StartSale();

// Output what initalize sale returns
print_r($Sale);

// Format order date/time
$timezone = new DateTimeZone("Europe/Copenhagen");
$date = new DateTime("now", $timezone);
$order_date_time = $date->format("Y-m-d\TH:i:s");

// Set header information
$Sale->StartSaleResult->ClientNumber = 996001;
$Sale->StartSaleResult->Date = $order_date_time;
$Sale->StartSaleResult->Employee = 1;
$Sale->StartSaleResult->NoteID = 123;
$Sale->StartSaleResult->Terminal = 1;
$Sale->StartSaleResult->Type = 'Sale';

// Itemline
$line = new stdClass();
$line->Type = 'Sale';
$line->ItemGroup = 1;
$line->Supplier = 1;
$line->Qty = 3;
$line->LineAmount = 600;
$line->EDBNumber = 1;
$line->DiscountAmount = 1-100;
$Sale->StartSaleResult->ItemLines->ItemLine[] = $line;

// Payment line, cash
$cash = new stdClass();
$cash->Type = 'Cash';
$cash->Qty = 1;
$cash->LineAmount = 600;
$Sale->StartSaleResult->PaymentLines->PaymentLine[] = $cash;

// Payment line, Change
$change = new stdClass();
$change->Type = 'Change';
$change->Qty = 1;
$change->LineAmount = -100;
$Sale->StartSaleResult->PaymentLines->PaymentLine[] = $change;

// Save sale
$response = $client->SaveSale($Sale->StartSaleResult, 'xxxxxxxx');

print_r($response);

输出连接时webservice返回的内容。

print_r($Sale);

你的数组看起来不太对。 ItemLines 和 PaymentLines 应该是数组，而不是包含数组的对象。

即使 StartSale 将它们作为对象返回，但在调用 SaveSale 时仍应该是一个数组。它们被返回为对象的原因是 PHP SoapClient 的一个怪癖。发生的情况是，如果数组中只有一个元素，则 SoapClient 会给你一个对象，并将其属性设置为单个元素的属性。但是如果数组中有多个元素，则会得到一个对象数组，因此比仅有单个元素时的结果深一层。因此，由于从 StartSale 中没有元素返回，所以它们被视为对象而不是空数组。

...
...
$Sale->StartSaleResult->ItemLines = array($line);

// Payment line, cash
$cash = new stdClass();
$cash->Type = 'Cash';
$cash->Qty = 1;
$cash->LineAmount = 600;

// Payment line, Change
$change = new stdClass();
$change->Type = 'Change';
$change->Qty = 1;
$change->LineAmount = -100;
$Sale->StartSaleResult->PaymentLines = array($cash, $change);

根据 WSDL 的格式，可能需要将参数作为关联数组传递，其中键为 sale 和 key（根据 WSDL），而不是分别传递两个参数：

$response = $client->SaveSale(array('sale' => $Sale->StartSaleResult, 'key' => 'xxxxxxxx'));

将sale和key更改为WSDL定义的任何内容。
