在Android中访问SD卡上传文件到我的PHP服务器使用phonegap

问题描述

我想从SD卡中选择一个文件并上传到服务器。是否有可能通过手机访问android中的SD卡作为我们如何从图库中上传图片和上传。我通过示例，但都是指定文件的名称也像例如：mnt / sdcard / read.txt。但我只想转到SD卡，以便用户可以选择自己的文件是可以做到的。

解决方案

  U很容易做到这一点非常简单
 
 window.requestFileSystem（LocalFileSystem.PERSISTENT，0，onFileSystemSuccessUpload，失败）; 
 
函数onFileSystemSuccessUpload（fileSystem）{
 //通过root获取目录条目并访问所有文件夹
 var directoryReader = fileSystem.root.createReader（）; 
 
 //获取目录中所有条目的列表
 directoryReader.readEntries（successReader，fail）; 
 
} 
 
函数successReader（entries）{
 var i; 
 for（i = 0; i< entries.length; i ++）{
 //alert（entries [i] .name）; 
 if（entries [i] .isDirectory == true）
 {
 var directoryReaderIn = entries [i] .createReader（）; 
 directoryReaderIn.readEntries（successReader，fail）; 
 
 
 $ b if（entries [i] .isFile == true）
 {
条目[i] .file（uploadFile，fail）; 
} 
} 
}; 
 
 function uploadFile（file）{
 var target =; //上传到服务器上的url 
 var ft = new FileTransfer（），path =file：//+ file.fullPath，name = file.name; 
 ft.upload（path，target，win，fail，{fileName：name}）; 
 // var ft = new FileTransfer（）; 
 //ft.upload(file.fullPath，target，win，fail，options）; 
 
 
函数win（r）{
 alert（Code =+ r.responseCode）; 
 alert（Response =+ r.response）; 
 alert（Sent =+ r.bytesSent）; 
 
 
函数失败（错误）{
 alert（发生错误：Code =+ error.code）; 
} 
} 
  

I want to go to select a file from sdcard and upload it to server. is it possible to access the sdcard in android via phonegap as how we are picking a image from gallery and uploading. I went through samples but all are specifying the file name also like eg: mnt/sdcard/read.txt. But i want to goto only sdcard so that user can select his own file is it possible to do.

解决方案

U can easily do that its very easy

    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccessUpload, fail);

    function onFileSystemSuccessUpload(fileSystem) {
     // get directory entry through root and access all the folders
             var directoryReader = fileSystem.root.createReader();

    // Get a list of all the entries in the directory
    directoryReader.readEntries(successReader,fail);

          }

      function successReader(entries) {
        var i;
        for (i=0; i<entries.length; i++) {
           //alert(entries[i].name);
           if(entries[i].isDirectory==true)
           {
             var directoryReaderIn = entries[i].createReader();
            directoryReaderIn.readEntries(successReader,fail);

           }

            if(entries[i].isFile==true)
             {
          entries[i].file(uploadFile, fail);
           }
        }
    };

 function uploadFile(file) {
var target=""; //the url to upload on server
     var ft = new FileTransfer(),path = "file://"+ file.fullPath,name = file.name;
                ft.upload(path, target, win, fail, { fileName: name });
               // var ft = new FileTransfer();
              //ft.upload(file.fullPath, target, win, fail, options);


            function win(r) {
                alert("Code = " + r.responseCode);
               alert("Response = " + r.response);
                alert("Sent = " + r.bytesSent);
            }

            function fail(error) {
                alert("An error has occurred: Code = " + error.code);
            }
}
