Android KSOAP2调试(上传图片到服务器)
Android KSOAP2调试log:
1.

这个要查看tomcat/logs/目录下的catalina.out信息，发现找不到新增的 Decoder.BASE64Decoder jar包，所以我把jar包放入tomcat/webapps/axis2/WEB-INF/lib下，重启服务，即可OK

原因：
客户端在使用request.addProperty("filename", filename)时候，第一个参数名字一定要和服务器的方法参数名字一模一样，否则因为对不上号而出现序列化错误。
如下是从android客户端上传一张图片到电脑服务器的代码，已经调试OK.
服务器代码：
ComplexTypeService.java文件
import java.io.File;
import java.io.FileOutputStream;
import Decoder.BASE64Decoder;
import data.DataForm;
public class ComplexTypeService
{
// 上传图像，imageByte参数表示上传图像文件的字节，
// length参数表示图像文件的字节长度（该参数值可能小于imageByte的数组长度）
public String uploadImage(String imageString)
{
FileOutputStream fos = null;
try{
String toDir = "/home/lsc/"; //存储路径
byte[] buffer = new BASE64Decoder().decodeBuffer(imageString); //对android传过来的图片字符串进行解码
File destDir = new File(toDir);
if(!destDir.exists()) destDir.mkdir();
fos = new FileOutputStream(new File(destDir, "wahaha.png")); //保存图片
fos.write(buffer);
fos.flush();
fos.close();
System.out.print("sclu success\n");
System.out.print(imageString);
return "上传图片成功!" + "图片路径为：" + toDir;
}catch (Exception e){
e.printStackTrace();
}
return "上传图片失败！";
}
// 返回一维字符串数组
public String[] getArray()
{
String[] strArray = new String[]{ "自行车", "飞机", "火箭" };
return strArray;
}
// 返回二维字符串数组
public String[] getMDArray()
{
String[] strArray = new String[]{ "自行车,飞机,火箭","中国,美国,德国", "超人,蜘蛛侠,钢铁侠" } ;
return strArray;
}
// 返回DataForm类的对象实例
public DataForm getDataForm()
{
return new DataForm();
}
// 将DataForm类的对象实例序列化，并返回序列化后的字节数组
public byte[] getDataFormBytes() throws Exception
{
java.io.ByteArrayOutputStream baos = new java.io.ByteArrayOutputStream();
java.io.ObjectOutputStream oos = new java.io.ObjectOutputStream(baos);
oos.writeObject(new DataForm());
return baos.toByteArray();
}
}
package data;
public class DataForm implements java.io.Serializable
{
private String name = "bill";
private int age = 20;
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public int getAge()
{
return age;
}
public void setAge(int age)
{
this.age = age;
}
