Android 开发笔记“调用.net webservice遇到的问题”
1、An exception occurred: org.ksoap2.SoapFault
SoapFault - faultcode: ‘soap:Server‘ faultstring: ‘服务器无法处理请求。 ---> 未能加载文件或程序集“MySql.Data, Version=6.3.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d”或它的某一个依赖项。系统找不到指定的文件。‘ faultactor: ‘null‘ detail: org.kxml2.kdom.Node@423841d0
原因：webservice 中采用了强类型数据集（DataSet）连接MySql数据库,简化数据库底层开发
解决：装一下mysql-connector-net-6.3.9.msi就可以了，文章下面有地址
2、Android访问webservice 帮助类，源码如下：
package com.sinobpo.nbsmt.webservice;import java.io.IOException;import java.io.UnsupportedEncodingException;import java.util.ArrayList;import java.util.Iterator;import java.util.List;import java.util.Map;import java.util.Set;import org.apache.http.NameValuePair;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.HttpClient;import org.apache.http.client.ResponseHandler;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpPost;import org.apache.http.impl.client.BasicResponseHandler;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.message.BasicNameValuePair;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpConnectionParams;import org.apache.http.params.HttpParams;import org.ksoap2.SoapEnvelope;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapPrimitive;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;public class WebServiceUtil { /** * .Net WebService调用方法 * * @param nameSpace * @param methodName * @param webServiceUrl * @param map * @return */ public static String doCallWebService(String nameSpace, String methodName, String webServiceUrl, Map map) { String xmlStr = null; SoapObject _soapObject = new SoapObject(nameSpace, methodName); // 如果有参数，设置调用方法参数 Set _keySet = map.keySet();// 返回键的集合 Iterator _iterator = _keySet.iterator(); while (_iterator.hasNext()) // 第一种迭代方式取键值 { Object key = _iterator.next(); _soapObject.addProperty(key.toString(), map.get(key)); } try { SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( SoapEnvelope.VER11); // 是否可以调用.netWebService envelope.dotNet = true; envelope.setOutputSoapObject(_soapObject); HttpTransportSE ht = new HttpTransportSE(webServiceUrl, 5000); ht.call(nameSpace + methodName, envelope); if (envelope.getResponse() != null) { SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); xmlStr = response.toString(); } } catch (Exception e) { System.out.println("prop: " + e.toString()); e.printStackTrace(); return null; } return xmlStr; } /** * Java WebService调用方法 * * @param nameSpace * @param methodName * @param webServiceUrl * @param map * @return */ public static String doCallWebServiceForJava(String nameSpace, String methodName, String webServiceUrl, Map map) { String xmlStr = null; // 创建httpTransportSE传输对象 HttpTransportSE ht = new HttpTransportSE(webServiceUrl); ht.debug = true; // 使用soap1.1协议创建Envelop对象 SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( SoapEnvelope.VER11); // 实例化SoapObject对象 SoapObject request = new SoapObject(nameSpace, methodName); /** * 设置参数，参数名不一定需要跟调用的服务器端的参数名相同，只需要对应的顺序相同即可 * */ // 如果有参数，设置调用方法参数 Set _keySet = map.keySet();// 返回键的集合 Iterator _iterator = _keySet.iterator(); while (_iterator.hasNext()) // 第一种迭代方式取键值 { Object key = _iterator.next(); request.addProperty(key.toString(), map.get(key)); } // request.addProperty("json", "YYYY"); // soapheader在这里 // Element[] header = new Element[1]; // Element lv = new Element().createElement(nameSpace, "json"); // lv.addChild(Node.TEXT, ""); // 将SoapObject对象设置为SoapSerializationEnvelope对象的传出SOAP消息 envelope.bodyOut = request; // envelope.dotNet = false; try { // 调用webService ht.call(null, envelope); if (envelope.getResponse() != null) { // SoapObject result = (SoapObject) envelope.bodyIn; // String name = envelope.bodyIn.toString(); System.out.println("envelope.getResponse()=" + envelope.getResponse().toString()); xmlStr = ""; } else { xmlStr = null; } } catch (Exception e) { System.out.println("prop: " + e.toString()); e.printStackTrace(); } return xmlStr; } public static String doCallWebServiceForPhp(String webServiceUrl) { String xmlStr = null; HttpParams httpParams = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout(httpParams, 5000); HttpConnectionParams.setSoTimeout(httpParams, 5000); HttpParams p = new BasicHttpParams(); p.setParameter("user", "1"); HttpClient httpclient = new DefaultHttpClient(p); HttpPost httppost = new HttpPost(webServiceUrl); List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); nameValuePairs.add(new BasicNameValuePair("user", "1")); try { httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); ResponseHandler<String> responseHandler = new BasicResponseHandler(); xmlStr = httpclient.execute(httppost, responseHandler); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return xmlStr; }}
3、invalid project description
a、此错误简单翻译为：无效的项目描述。点击错误对话框中的detail按钮，提示为：overlaps the location of another project的描述，翻译成中文也就是说导入的项目位置与另外一个项目重叠。
b、导致此错误的很有可能的原因之一为：此项目在eclipse的工作目录之下。所以，将项目拷贝到另一个目录下，然后再尝试导入，大部分情况下是可以解决此问题的。
