无法使用soap访问php中的.net webservice [英] Unable to access .net webservice in php using soap

问题描述

我有以下代码来创建一个Web服务。

< pre lang =c＃> [WebMethod] 
 public string EncryptText1（string明文）
 {
 
 ASCIIEncoding textConverter = new ASCIIEncoding（）; 
 byte [] key = textConverter.GetBytes（2a1c907916add59edffb3a4b）; 
 byte [] IV = textConverter.GetBytes（00000000）; 
 byte [] clearData = Encoding.ASCII.GetBytes（plaintext）; 
 byte [] cipherData = EncryptText（clearData，key，IV）; 
返回Convert.ToBase64String（cipherData）; 
} 
 [WebMethod] 
 public byte [] EncryptText（byte [] clearData，byte [] Key，byte [] IV）
 {
 
 MemoryStream ms = new MemoryStream（）; 
 TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider（）; 
 tdes.Mode = CipherMode.ECB; 
 tdes.Padding = PaddingMode.PKCS7; 
 ICryptoTransform alg = tdes.CreateEncryptor（Key，IV）; 
 CryptoStream cs = new CryptoStream（ms，alg，CryptoStreamMode.Write）; 
 cs.Write（clearData，0，clearData.Length）; 
 cs.FlushFinalBlock（）; 
 cs.Close（）; 
 byte [] encryptedData = ms.ToArray（）; 
返回encryptedData; 
} 

我有以下代码来访问php中的web服务

 <？php  
  $ enc_wsdl  =   http://172.18.0.75/EncryptionWS/EncryptionWS.asmx?wsdl; 
  $ enc_client  =  new  SoapClient（$ enc_wsdl）; 
  $ finalstring  = $ enc_client-> EncryptText1（  SomeUserName）; 
 print_r（$ finalstring）; 
 ？>  

但是我收到以下错误：

 致命错误：未捕获的SoapFault异常：[soap：Server]服务器无法处理请求。 --->字符串引用未设置为String的实例。参数名称：s在C中：\ xampp \\\ htdocs \ _dotnetwebservice \ index.php：4堆栈跟踪：＃0 C：\ xampp \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ > __ call（'EncryptText1'，Array）＃1 C：\ xampp\htdocs \ divnetwebservice \ index.php（4）：SoapClient->在C中抛出的EncryptText1（'SomeUserName'）＃2 {main} ：第4行的\ xampp \htdocs \dotnetwebservice \ index.php  

解决方案

enc_wsdl = http://172.18.0.75/EncryptionWS/EncryptionWS.asmx?wsdl;

enc_client = new SoapClient（

enc_wsdl）;

I have the following code to create a web service.

<pre lang="c#">[WebMethod]
        public string EncryptText1(string plaintext)
        {

            ASCIIEncoding textConverter = new ASCIIEncoding();
            byte[] key = textConverter.GetBytes("2a1c907916add59edffb3a4b");
            byte[] IV = textConverter.GetBytes("00000000");
            byte[] clearData = Encoding.ASCII.GetBytes(plaintext);
            byte[] cipherData = EncryptText(clearData, key, IV);
            return Convert.ToBase64String(cipherData);
        }
    [WebMethod]
    public byte[] EncryptText(byte[] clearData, byte[] Key, byte[] IV)
    {

        MemoryStream ms = new MemoryStream();
        TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
        tdes.Mode = CipherMode.ECB;
        tdes.Padding = PaddingMode.PKCS7;
        ICryptoTransform alg = tdes.CreateEncryptor(Key, IV);
        CryptoStream cs = new CryptoStream(ms, alg, CryptoStreamMode.Write);
        cs.Write(clearData, 0, clearData.Length);
        cs.FlushFinalBlock();
        cs.Close();
        byte[] encryptedData = ms.ToArray();
        return encryptedData;
    }

I have the following code to access the web service in php 

<?php
$enc_wsdl = "http://172.18.0.75/EncryptionWS/EncryptionWS.asmx?wsdl";
$enc_client = new SoapClient($enc_wsdl);
$finalstring = $enc_client->EncryptText1("SomeUserName");
print_r($finalstring);
?>

but I am getting the following error: 

Fatal error: Uncaught SoapFault exception: [soap:Server] Server was unable to process request. ---> String reference not set to an instance of a String. Parameter name: s in C:\xampp\htdocs\dotnetwebservice\index.php:4 Stack trace: #0 C:\xampp\htdocs\dotnetwebservice\index.php(4): SoapClient->__call('EncryptText1', Array) #1 C:\xampp\htdocs\dotnetwebservice\index.php(4): SoapClient->EncryptText1('SomeUserName') #2 {main} thrown in C:\xampp\htdocs\dotnetwebservice\index.php on line 4

解决方案

enc_wsdl = "http://172.18.0.75/EncryptionWS/EncryptionWS.asmx?wsdl";

enc_client = new SoapClient(

enc_wsdl);
