调用webservice 出现error writing to socket错误

您好,请在代码调用写入前判定当前网络是否还正常连接即可.您的网络已经断开连接了.此种错误如果是单纯的API调用webservice的话..基本是无法解决的.可以尝试重试连接这个方法

socket 和 webservice 的区别和比较

webservice 有一个 socket 难以比拟的优势：webservice基于HTTP协议，是无状态的，因此可以例如现有非常成熟的Web集群来提供高负载，同比之下 socket 就非常难。socket其实也可以无状态，连一下就断开.webservice就是这么做的。

怎么在c语言中用socket的方式调用webservice

可以实现，先connectsockaddr_in server;if (m_bSockConnected) {return TRUE;}server.sin_addr.s_addr= inet_addr(m_szHost);server.sin_family= AF_INET;server.sin_port= htons((UINT)m_nPort);if(connect(m_socket, (struct sockaddr*)&server, sizeof(server)) == SOCKET_ERROR){m_bSockConnected = FALSE;m_nLastErrorNo = WSAGetLastError();MessageBox(0, "请检网络和服务器", "网络连接错误", 0);return FALSE; }else{m_bSockConnected = TRUE;}int timeout=30;setsockopt(m_socket, SOL_SOCKET, SO_RCVTIMEO, (const char*)&timeout, sizeof(int));然后再发送urlchar requestHeader= {0};char nBuf= {0};strcpy(requestHeader, "PUT ");strcat(requestHeader, szUrl);strcat(requestHeader, "&Content-Length=");_ui64toa(contentLength + 8, nBuf,10); //额外加了传输完成头的长度是8 strlen(SEND_END_STRING)strcat(requestHeader, nBuf);strcat(requestHeader, "&FileCount=");ltoa(fileCount,nBuf, 10);strcat(requestHeader, nBuf);strcat(requestHeader," HTTP/1.1\r\nContent-Length: ");_ui64toa(contentLength + 8, nBuf, 10);strcat(requestHeader,nBuf);strcat(requestHeader,"\r\nHost: ");strcat(requestHeader,m_szHost);strcat(requestHeader,":");itoa(m_nPort,nBuf,10);strcat(requestHeader,nBuf);strcat(requestHeader,"\r\nAccept: */*;\r\nAccept-Encoding: gzip,deflate\r\nKeep-Alive: 60000\r\nConnection: keep-alive\r\n\r\n");//MessageBox(0, requestHeader, "info", 0);char * szUTF8 = NULL;BOOLbRet = FALSE;bRet = CCharTransLib::EncodeToUTF8(requestHeader,&szUTF8);if (bRet){if ( (int)strlen(szUTF8) != send(m_socket, szUTF8, strlen(szUTF8), 0)){m_nLastErrorNo = GetLastError();bRet = FALSE;}if (szUTF8){delete szUTF8;szUTF8 = NULL;}}以上是从我工程里面摘的，可能有些变量楼主编译不过去，但基本思想就是这样的

webservice上面的socket通信

WebService好像搞不了Socket通信的吧 WebService本来就是通信的

WebService、Restful、Http、Socket

1、 WebService到底是什么？ 2、 Web service是什么？ 3、 什么是WEBService，实现WEBService有哪些框架，为什么WEBService经常被认为太重了，只有银行和大型国企才会使用的更多有一些？4、 理解RESTful架构 5、 WebService入门介绍

linux-weblogic下调用webservice服务时报java.net.SocketException: Broken pipe，如何解决

服务器的网络环境呢？估计跟防火墙之类有关另外，WS不适合批量调用，可以的话，至少改成多笔数据放在一批里面处理

如何实现WebService与Socket通信

WebService-基于-HTTP-基于-TCP而socket是TCP的应用。socket开发的东西可以很简单的兼容所有HTTP请求：包括长/短连接。而HTTP是短连接的。所以socket应用程序需要做调整，改一下解析包文的处理机制即可。WebService只不过是些xml格式的报文，也叫soap.对于精通网络编程（socket）的人来说这一点都不难，希望你能找到开发这个socket程序的人让他修改一下代码即可。

JAVA怎样调用https类型的webservice

***隐藏网址***第二步就是介绍怎样生成证书，先写一个InstallCert.java类放到自己电脑的D盘根目录下，（注意这个类是没有包名的）类中代码如下：/** * */import java.io.BufferedReader; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.InputStream; import java.io.InputStreamReader; import java.io.OutputStream; import java.security.KeyStore; import java.security.MessageDigest; import java.security.cert.CertificateException; import java.security.cert.X509Certificate; import javax.net.ssl.SSLContext; import javax.net.ssl.SSLException; import javax.net.ssl.SSLSocket; import javax.net.ssl.SSLSocketFactory; import javax.net.ssl.TrustManager; import javax.net.ssl.TrustManagerFactory; import javax.net.ssl.X509TrustManager; public class InstallCert { public static void main(String args) throws Exception { String host; int port; char passphrase; if ((args.length == 1) || (args.length == 2)) { String.split(":"); host = c; port = (c.length == 1) ? 443 : Integer.parseInt(c); String p = (args.length == 1) ? "changeit" : args; passphrase = p.toCharArray(); } else { System.out .println("Usage: java InstallCert 《host》"); return; } File file = new File("jssecacerts"); if (file.isFile() == false) { char SEP = File.separatorChar; File dir = new File(System.getProperty("java.home") + SEP + "lib" + SEP + "security"); file = new File(dir, "jssecacerts"); if (file.isFile() == false) { file = new File(dir, "cacerts"); } } System.out.println("Loading KeyStore " + file + "..."); InputStream in = new FileInputStream(file); KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType()); ks.load(in, passphrase); in.close(); SSLContext context = SSLContext.getInstance("TLS"); TrustManagerFactory tmf = TrustManagerFactory .getInstance(TrustManagerFactory.getDefaultAlgorithm()); tmf.init(ks); X509TrustManager defaultTrustManager = (X509TrustManager) tmf .getTrustManagers(); SavingTrustManager tm = new SavingTrustManager(defaultTrustManager); context.init(null, new TrustManager { tm }, null); SSLSocketFactory factory = context.getSocketFactory(); System.out .println("Opening connection to " + host + ":" + port + "..."); SSLSocket socket = (SSLSocket) factory.createSocket(host, port); socket.setSoTimeout(10000); try { System.out.println("Starting SSL handshake..."); socket.startHandshake(); socket.close(); System.out.println(); System.out.println("No errors, certificate is already trusted"); } catch (SSLException e) { System.out.println(); e.printStackTrace(System.out); } X509Certificate chain = tm.chain; if (chain == null) { System.out.println("Could not obtain server certificate chain"); return; } BufferedReader reader = new BufferedReader(new InputStreamReader( System.in)); System.out.println(); System.out.println("Server sent " + chain.length + " certificate(s):"); System.out.println(); MessageDigest sha1 = MessageDigest.getInstance("SHA1"); MessageDigest md5 = MessageDigest.getInstance("MD5"); for (int i = 0; i 《 chain.length; i++) { X509Certificate cert = chain; System.out.println(" " + (i + 1) + " Subject " + cert.getSubjectDN()); System.out.println(" Issuer " + cert.getIssuerDN()); sha1.update(cert.getEncoded()); System.out.println(" sha1 " + toHexString(sha1.digest())); md5.update(cert.getEncoded()); System.out.println(" md5 " + toHexString(md5.digest())); System.out.println(); } System.out .println("Enter certificate to add to trusted keystore or ’q’ to quit: "); String line = reader.readLine().trim(); int k; try { k = (line.length() == 0) ? 0 : Integer.parseInt(line) - 1; } catch (NumberFormatException e) { System.out.println("KeyStore not changed"); return; } X509Certificate cert = chain; String alias = host + "-" + (k + 1); ks.setCertificateEntry(alias, cert); OutputStream out = new FileOutputStream("jssecacerts"); ks.store(out, passphrase); out.close(); System.out.println(); System.out.println(cert); System.out.println(); System.out .println("Added certificate to keystore ’jssecacerts’ using alias ’" + alias + "’"); } private static final char HEXDIGITS = "0123456789abcdef".toCharArray(); private static String toHexString(byte bytes) { StringBuilder sb = new StringBuilder(bytes.length * 3); for (int b : bytes) { b &= 0xff; sb.append(HEXDIGITS); sb.append(HEXDIGITS); sb.append(’ ’); } return sb.toString(); } private static class SavingTrustManager implements X509TrustManager { private final X509TrustManager tm; private X509Certificate chain; SavingTrustManager(X509TrustManager tm) { this.tm = tm; } public X509Certificate getAcceptedIssuers() { throw new UnsupportedOperationException(); } public void checkClientTrusted(X509Certificate chain, String authType) throws CertificateException { throw new UnsupportedOperationException(); } public void checkServerTrusted(X509Certificate chain, String authType) throws CertificateException { this.chain = chain; tm.checkServerTrusted(chain, authType); } } } 将上面的InstallCert.java编译成InstallCert.class文件放到自己电脑的D盘根目录下。这是正常的情况下D盘根目录下会有3个文件，如下图：打开cmd进入到d盘开始执行生成证书命令，我这里不便于那我的网址测试我用支付宝的网址来测试的，输入：java InstallCert www.alipay.com 如下图当出现了：Enter certificate to add to trusted keystore or ’q’ to quit: 这行代码时，输入1，回车。正常执行完后在D盘根目录下就会出现证书“jssecacerts”文件，具体如下图：6得到证书后将证书拷贝到$JAVA_HOME/jre/lib/security目录下，我这里是win7系统，在尝试的过程中需要将证书重命名为：cacerts 放进去才会有用。（这个步骤在不同的环境和操作系统下有点不同，需要注意）
