如何在 Java 中發送原始 SOAP 請求？

Question

我需要向服務器發送原始 SOAP 請求。 我的請求看起來像

POST http://10.76.243.43:8080/registry/services/xds-iti18 HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: application/soap+xml;charset=UTF-8
Content-Length: 6383
Host: 10.76.243.43:8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

         </urn2:AdhocQuery>
      </urn:AdhocQueryRequest>
   </soap:Body>
</soap:Envelope>

它是由 SOAP UI（使用 Web 服務的 wsdl）生成的標准原始請求，所以如果我將它發送到那里，我會得到 HTTP 代碼 200 和一些正常響應。 我想使用 Java 發送它，所以我執行以下操作

byte[] encoded = Files.readAllBytes(Paths.get("C:\\Users\\timofb\\Documents\\testtest.txt"));//file with my raw request
String soapXml = new String(encoded, StandardCharsets.UTF_8);
Socket socket = new Socket("10.76.243.43", 8080);
BufferedWriter out = new BufferedWriter(
            new OutputStreamWriter(socket.getOutputStream(), "UTF8"));
BufferedReader in = new BufferedReader(
            new InputStreamReader(socket.getInputStream()));
out.write(soapXml);
out.flush();
System.out.println("\n * Response");    
String line;
while ((line = in.readLine()) != null) {
     System.out.println(line);
}
in.close();

我收到 HTTP 狀態 500 和處理時發生錯誤的 SOAP 消息。 謝謝。

Answer 1

你可以這樣嘗試：你需要用你的替換xmldata：

   try {
        String xmldata = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><soapenv:Envelopey> your reuest</soapenv:Envelope>";
        String hostname = "10.76.243.43";
        int port = 8080;
        InetAddress addr = InetAddress.getByName(hostname);
        Socket sock = new Socket(addr, port);

        //Send header
        String path = "registry/services/xds-iti18";
        BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(sock.getOutputStream(), "UTF-8"));
        wr.write("POST "+path + " HTTP/1.1\r\n");
        wr.write("Host: "+hostname+":"+port+"\r\n");
        wr.write("Content-Length: "+ xmldata.length() + "\r\n");
        wr.write("Content-Type: application/soap+xml; charset=\"utf-8\"\r\n");
        wr.write("\r\n");            //Send data
        wr.write(xmldata);
        wr.flush();

        // Response
        BufferedReader rd = new BufferedReader(new InputStreamReader(sock.getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {
          System.out.println("Response:"+line);
        }
} catch (Exception e) {
   e.printStackTrace();
}

Answer 2

我找到了答案。 這段代碼對我有用

    byte[] encoded = Files.readAllBytes(Paths.get("C:\\Users\\timofb\\Documents\\test.txt"));
    String soapXml = new String(encoded, StandardCharsets.UTF_8);
    SOAPConnectionFactory soapConnectionFactory =
            SOAPConnectionFactory.newInstance();
    java.net.URL endpoint = new URL("http://" + ip + "/cs-repository/services/xds-iti41");
    SOAPConnection connection = soapConnectionFactory.createConnection();
    MessageFactory factory = MessageFactory.newInstance();
    SOAPMessage message = factory.createMessage(new MimeHeaders(), new ByteArrayInputStream(encoded));
    AttachmentPart attachment = message.createAttachmentPart();
    attachment.setContent("sm_content", "text/plain");
    attachment.setContentId("1.9f910338bf0cac0e783bfdec7e53be9237684caa8f8f4e6d@apache.org");
    message.addAttachmentPart(attachment);
    SOAPMessage response = connection.call(message, endpoint);
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    response.writeTo(out);
    String strMsg = new String(out.toByteArray());
    return strMsg;

Answer 3

我知道這有點晚了，但 Unirest 救了我很多。

您應該簡單地嘗試以下操作：

        Unirest.setTimeouts(0, 0);
        HttpResponse<String> response = Unirest.post("YOUR URL OPERATION")
          .header("Content-Type", "application/soap+xml")
          .body("YOUR RAW FILE")
          .asString();

Answer 4

您可以使用 java HttpURLConnection 代替套接字，在這里您必須正確設置 SOAPAction 標頭屬性，以防它是“AdhocQueryRequest”，或者您可以從您的 wsdl 進行交叉檢查，以下是未經測試的暫定代碼。

    URL url = new URL(SOAPUrl);
    URLConnection connection = url.openConnection();
    HttpURLConnection httpConn = (HttpURLConnection) connection;
    FileInputStream fin = new FileInputStream(xmlFile2Send);

    ByteArrayOutputStream bout = new ByteArrayOutputStream();

    // Copy the SOAP file to the open connection.
    copy(fin,bout);
    fin.close();

    byte[] b = bout.toByteArray();

    // Set the appropriate HTTP parameters.
    httpConn.setRequestProperty( "Content-Length",
                                 String.valueOf( b.length ) );
    httpConn.setRequestProperty("Content-Type","text/xml; charset=utf-8");
      httpConn.setRequestProperty("SOAPAction",SOAPAction);
    httpConn.setRequestMethod( "POST" );
    httpConn.setDoOutput(true);
    httpConn.setDoInput(true);

    // Everything's set up; send the XML that was read in to b.
    OutputStream out = httpConn.getOutputStream();
    out.write( b );    
    out.close();

    // Read the response and write it to standard out.

    InputStreamReader isr =
        new InputStreamReader(httpConn.getInputStream());
    BufferedReader in = new BufferedReader(isr);

    String inputLine;

    while ((inputLine = in.readLine()) != null)
        System.out.println(inputLine);

    in.close();
