java - 为什么我会收到 java.net.SocketException : Connection reset error from web service through SOAP UI and Java client?

Question

我正在将一个可视化的 foxpro 应用程序转换为一个 Java Web 应用程序，并且该应用程序的一个很小但很重要的部分向 Web 服务发出了一个 SOAP 请求。

我已经编写了 3 个测试客户端来调用此 Web 服务，并且我还通过 SOAP UI 进行了测试。我对此 Web 服务的每一项测试都返回错误:java.net.SocketException: Connection reset。所以我显然在每种测试方法中都遗漏了同样的事情，或者做错了同样的事情。

我有foxpro代码，我已经通过foxpro成功提交了请求并收到了有效的回复。但是我对 Foxpro 没有任何经验，所以我一直在努力解决 Foxpro 中有效的代码与我用 java 编写的新代码之间的差异。

我希望对 Soap 和 Web 服务有更多经验的人可以看到我的代码，也许可以自己尝试一下，并帮助我了解问题所在。

我将提供网络服务 url 以及我所有的代码。我还将提供有效的 foxpro 命令行代码。

foxpro 代码使用 CreateObject("Microsoft.XMLHTTP") .我通过研究了解到，这也用于 ASP、VB.net 和 C#。

1)这是我需要调用的网络服务:

主持人:https://rlisapi.myfwc.com/
SOAP 端点:https://rlisapi.myfwc.com/wsReceipts.asmx
WSDL:https://rlisapi.myfwc.com/wsReceipts.asmx?WSDL
此 Web 服务不包含 ws-security。凭据在请求本身中。当然，我无法提供这些，但我认为不需要它们来帮助我解决连接重置问题。

2) 我创建的第一个客户端使用了 SAAJ API。这是我的代码:

(3)我的客户端下个版本用的是Socket和OutputStreamWriter

    public List<BusinessEntityTransaction> getCurrentTransactions(PaymentCart paymentCart) {
        List<BusinessEntityTransaction> transactionList = new ArrayList<BusinessEntityTransaction>();
        List<RlisTransaction> rlisList = new ArrayList<RlisTransaction>();
        try {
            logger.info("Adding current transactions from RLIS system...");
            rlisList = this.getCurrentTransactionsViaXmlHttp();         
            for (RlisTransaction tx : rlisList){
                //add transaction received from web service to transactionList
            }

        } catch (UnsupportedOperationException e) {
            e.printStackTrace();
        }
        // do something with the rlisList 
        return transactionList;
    }

    private List<RlisTransaction> getCurrentTransactionsViaXmlHttp(){
        List<RlisTransaction> rlisTransactions = new ArrayList<RlisTransaction>();

        String xmldata = "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" +

        try{

          //Create socket
          String hostname = "rlisapi.myfwc.com";
          int port = 443;
          InetAddress  addr = InetAddress.getByName(hostname);

          String line;
          while((line = rd.readLine()) != null)
          System.out.println(line);

        } catch (Exception e) {
              e.printStackTrace();
        }

        return rlisTransactions;
    }

}

(4) 我有一个类似的使用 HttpUrlConnection 的测试客户端

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class TestXmlClient {

    public static void main(String[] args) {
        String argUrl = "https://rlisapi.myfwc.com/wsReceipts.asmx";

        System.out.println("Test XML Client");

        String requestXml = 
                "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
                "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" +
                "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" " +
                "xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\">" +
                "<soap:Body>" +
                "<getDailyReceipts xmlns=\"http://api.outdoorlicensesolution.com/RLIS/\">" +
                "<Content-Length>494</Content-Length>" +
                "<ConsumerPIN>my-consumer-pin</ConsumerPIN>" +
                "<AgentID>000</AgentID>" +  //not real agent id
                "<ReceiptDate>2013-07-01T00:00:00</ReceiptDate>" +
                "</getDailyReceipts>" +
                "</soap:Body>" +
                "</soap:Envelope>" ;

        System.out.println("Request: " + requestXml);

        //try {
        URL url;
        OutputStreamWriter writer = null;
        InputStreamReader reader = null;
        HttpURLConnection con = null;

        try {
            url = new URL (argUrl);
        con = (HttpURLConnection) url.openConnection();

        URLConnection urlc = url.openConnection();
        HttpURLConnection httpc = (HttpURLConnection)urlc;
        // only interested in the length of the resource
        httpc.setRequestMethod("HEAD");
        int len = httpc.getContentLength();

        System.out.println("length: " + len);

        // specify that we will send output and accept input
        con.setDoInput(true);
        con.setDoOutput(true);

        con.setConnectTimeout( 20000 );  // long timeout, but not infinite
        con.setReadTimeout( 20000 );

        con.setUseCaches (false);
        con.setDefaultUseCaches (false);

        // tell the web server what we are sending
        //con.setRequestProperty ( "Content-Type", "text/xml" );
        con.setRequestProperty ( "Content-Type", "text/xml; charset=utf-8" );
        //con.setRequestProperty("Connection", "close"); 

        writer = new OutputStreamWriter( con.getOutputStream() );

        writer.write(requestXml);
        writer.flush();
        writer.close();

        // reading the response
        reader = new InputStreamReader( con.getInputStream() );
        StringBuilder buf = new StringBuilder();
        char[] cbuf = new char[ 2048 ];
        int num;
        while ( -1 != (num=reader.read( cbuf ))) {
            buf.append( cbuf, 0, num );
        }
        String result = buf.toString();
        System.err.println( "\nResponse from server after POST:\n" + result );

        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            System.out.println(e.getStackTrace());
            e.printStackTrace();
        } catch (Exception e){
            e.printStackTrace();
        } finally{
            if (writer != null) { 
                try { 
                    writer.close(); 
                } catch (Exception e) { 
                    // ignore... 
                } 
            }
            if (reader != null) { 
                try { 
                    reader.close(); 
                } catch (Exception e) { 
                    // ignore... 
                } 
            } 

            if (con != null) { 
                try { 
                    con.disconnect(); 
                } catch (Exception e) { 
                    // ignore... 
                } 

            }   
        }
    }
}

最后，除了所有这些测试客户端，我还尝试使用 SOAP UI 提交各种请求。有趣的是，我无法从 url 加载 wsdl，所以我将 wsdl 源代码保存到本地文件并使用它。

这是 Soap UI 从 wsdl 文件生成的请求:

<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:rlis="http://api.outdoorlicensesolution.com/RLIS/">
   <soap:Header/>
   <soap:Body>
      <rlis:getDailyReceipts>
         <!--Optional:-->
         <rlis:ConsumerPIN>?</rlis:ConsumerPIN>
         <rlis:AgentID>?</rlis:AgentID>
         <rlis:ReceiptDate>?</rlis:ReceiptDate>
      </rlis:getDailyReceipts>
   </soap:Body>
</soap:Envelope>

本地保存的 WSDL:

从我过去几天的所有研究中，我确定这个错误最常见的原因是服务器在客户端完成读取之前关闭了连接。

起初我认为 Web 服务本身有问题，但由于我能够运行 foxpro 命令并获得有效响应，因此情况并非如此。

我也尝试更改 Soap UI 设置中的许多首选项，包括套接字超时。

此外，我的请求不通过代理服务器。

任何建议或意见将不胜感激!
谢谢。

然后重复这一系列消息。

所以我认为这表明首先有一个来自客户端的连接请求，该请求被服务器确认。
然后是客户端问候、服务器问候、握手协议(protocol)证书、服务器问候完成、客户端 key 交换、更改密码规范、加密握手消息，最后是来自服务器的连接重置 (RST)。

我查了一下最后一帧的专家信息是什么意思，看起来它可能意味着协议(protocol)序列可疑，例如序列不连续或检测到重传...

这仍然让我挠头!我不明白我可能在我的代码中做什么，或者从可能导致此连接从服务器重置的 Soap UI。以及为什么它不会从 Foxpro 代码中的 Microsoft.XMLHTTP 帖子中发生......难道我的请求是作为片段发送的，而服务器不会接受它？

我想我将在运行 foxpro 命令时尝试运行 wireshark 捕获，但那是在装有 Windows 8 的 PC 上，所以我需要首先弄清楚如何在管理员下运行它。我正在运行的用于重置连接的 Java 测试客户端在我的 mac 上。

与此同时，有没有人有任何进一步的见解？

Answer 1

如我所见，您的所有示例都应该正常工作。

我建议您使用一些数据包跟踪软件，如wireshark 或 fiddler，并检查请求/响应 header 。在请求 OutputStream 之前，您可能需要在连接上设置一些额外的信息(UserAgent 等)

================ 更新 ======================

正如您所指定的，服务器要求您启用 SSLv3。
在建立连接之前使用它

System.setProperty("https.protocols", "SSLv3");

我在我的测试中做了这个，它似乎连接，因为我可以将soap消息写入OutputStream，但是我从服务器收到500错误，这是一件好事，因为这是一个werbservice内部故障

现在你需要找出soap消息有什么问题，或者消息数据

================ 更新 2 ======================

固定!

为了澄清，我正在使用 测试编号 4 ( HttpUrlConnection )

邮件第 3 行末尾缺少空格

"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"" +

应该是

"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" " +

原因与 xmlns:xsd 相关联定义。
