我要把本地的文件上传到服务器上面去：
<p:fileUpload value="#{resourceListAction.file}" id="file" mode="simple"></p:fileUpload>
<p:commandButton value="上传文件" action="#{resourceListAction.insertResource()}" type="submit" ajax="false" update="reFreshData">
</p:commandButton>
后端insertResource方法调用upload方法
/**
* 上传文件到服务器
*/
public boolean upload(UploadedFile file,String resname) throws Exception{
Saml2SignResponse response = (Saml2SignResponse) JsfHelper.getSessionValue("loginUser");
String tenantId = response.getTenantId();
String savePath = "http://www.pdsdemo.com:8280/fsc/v1/"+tenantId+"/"+resname;
try{
InputStream in = new BufferedInputStream(file.getInputstream());
try{
byte[] buffer = new byte[64*1024];
FileOutputStream fileOutputStream = new FileOutputStream(savePath);
while(in.read(buffer)>0){
fileOutputStream.write(buffer);
}
}finally{
in.close();
}
return true;
}catch (Exception e) {
// TODO: handle exception
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_FATAL,e.getClass().getName(),e.getMessage());
FacesContext.getCurrentInstance().addMessage(null, message);
return false;
}
}
savePath为路径 ，但是服务器端有鉴权（身份认证），鉴权通过才能上传文件，需要在请求头 加参数Authorization 有一个demo是用jsp 、ajaxForm来搞的 设置了请求头：
function selectfile(){
var ofileName = $("#upload_file_input");
var fname = ofileName[0].value;
fname = fname.replace(/\/g, "/");
var filename=fname.substr(fname.lastIndexOf(""/"")+1, fname.length);
var options = {
target: ""#upload_file_input"",
url:""http://www.pdsdemo.com:8280/fsc/v1/""+filename,
type:"POST",
beforeSend:function(request){
request.setRequestHeader("Authorization", "Bearer <%=token%>");
},
success: function(data) {
var savefilename = data.path.substr(data.path.lastIndexOf(""/"")+1, data.path.length);
window.opener.document.getElementById("concreteMaterial.filename").value = savefilename;
window.opener.document.getElementById("concreteMaterial.filesize").value = data.size;
}
};
// 将options传给ajaxForm
$(""#upload_form"").ajaxForm(options);
}
<form method="POST" id="upload_form" >
<input id="upload_file_input" type="file" size="3" name="file" onchange="selectfile();"/>
<input type="submit" name="submit" value="submit">
</form>
我该如何改造我的代码达到效果呢？ 各位大牛求方案 |

可以使用filter 解决吧… 或者删除权限了..上传文件

你这是 服务端和客户端要验证TOKEN，你给的例子上，人家用的是http POST请求，在http head里添加 Authorization，用来存token。
你要学着来，就按下面代码 public class Upload
{
public Upload(){
String filePath="D:\DataSocketServer.java";
String fileName="DataSocketServer.java";
try{
URL url=new URL("http://localhost:8080//TestServlet3");
HttpURLConnection connection=(HttpURLConnection)url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
BufferedOutputStream out=new BufferedOutputStream(connection.getOutputStream());
File file=new File(filePath);
FileInputStream fis=new FileInputStream(file);
byte[] bytes=new byte[1024];
int numReadByte=0;
while((numReadByte=fis.read(bytes,0,1024))>0){
out.write(bytes,0,numReadByte);
}
out.flush();
fis.close();
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args){
new Upload();
}
}
