美好的一天，到目前为止，我正在开发一个带有cordova的应用程序，我在上传时遇到问题，但是没有实现它的工作。
我在网络搜索中搜索以找到问题，但我无法理解，当cordova应用程序调用服务（struts2服务）时，文件始终为null并使服务崩溃。
这是cordova应用程序代码：
enviarLogs: function(archivo, url){
log.info("inicio-fileManager.enviarArchivo");
//obtenemos el archivo que deseamos enviar
log.logFolder.getFile(archivo,{create: false, exclusive:false},
function logCapturado(adjunto){
log.info("fileManager.enviarArchivo: archivo encontrado, preparando envio");
//notificaciones.alertar("Salida URI: "+encodeURI(adjunto.fullPath));
//notificaciones.alertar("Salida URI: "+encodeURI(adjunto.toURL()));
//var location = "/data/data/ve.com.megasoft.MobilePOS/files/logs/MobilePOSLOGS2015-01-26.txt";
//opciones del archivo
var fileOptions = new FileUploadOptions();
fileOptions.fileKey ="myFile";
fileOptions.fileName = archivo;
fileOptions.mimeType = "text/plain";
//fileOptions.chunkedMode = false;
//fileOptions.headers = {
//Connection: "close"
//};
//identificacion de procedencia del archivo
var info = new Object();
info.value1 = "test";
info.value2 = "Case";
fileOptions.params = info;
//realizamos el envio del archivo
var ft = new FileTransfer();
ft.upload(
//location,
adjunto.toURL(),
encodeURI(url),
fileManager.success,
fileManager.fail,
fileOptions,
true
);
},
function logNoCapturado(error){
log.error("fileManager.enviarArchivo: Archivo no encontrado, cancelando envio");
notificaciones.alertar(
"no se encuentra el log solicitado, no se realizara el envio de informacion",
undefined,
"Error"
);
}
);
log.info("fin-fileManager.enviarArchivo");
}
以下是struts2服务中的操作：
package ve.com.megasoft;
import java.io.File;
import org.apache.commons.io.FileUtils;
import java.io.IOException;
import com.opensymphony.xwork2.ActionSupport;
public class UploadFile extends ActionSupport{
private static final long serialVersionUID = 1L;
private File myFile;
private String myFileContentType;
private String myFileFileName;
private String destPath;
public String execute() {
/* Copy file to a safe location */
destPath = "C:\\test";
try{
System.out.println("Src File name: " + myFile);
System.out.println("Dst File name: " + myFileFileName);
File destFile = new File(destPath, myFileFileName);
FileUtils.copyFile(myFile, destFile);
}catch(IOException e){
e.printStackTrace();
return ERROR;
}
return SUCCESS;
}
public File getMyFile() {
return myFile;
}
public void setMyFile(File myFile) {
this.myFile = myFile;
}
public String getMyFileContentType() {
return myFileContentType;
}
public void setMyFileContentType(String myFileContentType) {
this.myFileContentType = myFileContentType;
}
public String getMyFileFileName() {
return myFileFileName;
}
public void setMyFileFileName(String myFileFileName) {
this.myFileFileName = myFileFileName;
}
}
感谢您的帮助，希望您能帮助我。
编辑：添加了包：
