실제 매개 변수는 어디에 전달됩니까?

Question

나는 android와 함께 phonegap에서 일하고있다. 파일을 내 서버에 업로드하고 싶습니다. 나는이 링크에서 도움을 촬영 한 -

이는 다음과 같습니다 :이 클래스 내 fileuploader.java

package com.beetight; 

import com.phonegap.*; 
import android.os.Bundle; 

public class fileupload extends DroidGap { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     super.loadUrl("file:///android_asset/www/index.html"); 
    } 
}

이 내 fileuploader.js입니다 :

FileUploader.prototype.uploadByUri = function(server, file, params, fileKey, fileName, mimeType, callback, fail) { 

    return PhoneGap.exec(function(args) { 
     callback(args); 
    }, function(args) { 
if(typeof fail == 'function') { 
fail(args); 
} 
    }, 'FileUploader', 'uploadByUri', [server, file, params, fileKey, fileName, mimeType]); 
}; 
FileUploader.prototype.upload = function(server, file, params, fileKey, fileName, mimeType, callback, fail) { 

    return PhoneGap.exec(function(args) { 
if(typeof callback == 'function') { 
callback(args); 
} 
    }, function(args) { 
if(typeof fail == 'function') { 
fail(args); 
} 
    }, 'FileUploader', 'upload', [server, file, params, fileKey, fileName, mimeType]); 
}; 


FileUploader.Status = { 
PROGRESS: "PROGRESS", 
COMPLETE: "COMPLETE" 
} 

PhoneGap.addConstructor(function() { 
PhoneGap.addPlugin('fileUploader', new FileUploader()); 
PluginManager.addService("FileUploader","com.beetight.FileUploader"); 
}); 

이 내 전체 코드입니다 ..하지만 난 다음이 프로젝트를 실행 할 때마다 내가 아무것도하지 않습니다. 내가 어디 서버에 업로드하려는 내 서버 이름, 파일의 실제 매개 변수를 전달 해야할지 모르겠다. 그래서 내 서버 이름과 그 파일의 이름을 서버에 업로드하고 싶으면 어떻게 제안 해주십시오. 나는 phonegap 프로그램에서 매우 신선하다. 미리 알려주세요.

Answer 1

이 코드를 감안할 때 그것은 기대

var uploader = FileUploader(); 
uploader.upload("http://yourserver-here.com", //<-- this is where you put your server 
     "myfile.txt", //<-- The file you want to upload 
     {} , //Not sure what this parameters is for, perhaps adding QS to server path 
     "file", //Filekey, using the default from Fileuploader.java 
     "myfile.txt", //filename 
     "text/plain", //file mime-type 
     function(args) {  //callback. 
      alert("Callback"); //Not sure if this means success or if you have to check args 
     }, 
     function(args) {  //callback on failure. 
      alert("Failed"); 
     });
