HTML5 fileWriter.write不写入本地文件

问题描述

我正在研究HTML5 FileSystem-API的教程。
基本上我想把文件写到我的机器上。我使用python的simpleHTTPServer来为网站服务。一旦我加载网页，控制台不会引发错误，我收到一条消息，表明写入成功。但我无法在我的机器上的任何地方找到该文件。这是我的代码：

I am working on the tutorial for HTML5 FileSystem-API.Basically I would like to write a file to my machine. I am using python's simpleHTTPServer to serve the website. Once I load the webpage, the console doesn't raise an error and I get a message that the write was successful. But I can't find the file anywhere on my machine. Here is my code:

function onInitFs(fs) {

  fs.root.getFile('zz11zzlog.txt', {create: true}, function(fileEntry) {

    // Create a FileWriter object for our FileEntry (log.txt).
    fileEntry.createWriter(function(fileWriter) {

      fileWriter.onwriteend = function(e) {
        console.log('Write completed.');
      };

      fileWriter.onerror = function(e) {
        console.log('Write failed: ' + e.toString());
      };

      // Create a new Blob and write it to log.txt.
      var blob = new Blob(['Lorem Ipsum'], {type: 'text/plain'});

      fileWriter.write(blob);

    }, errorHandler);

  }, errorHandler);

}

function errorHandler(e) {
  var msg = '';

  switch (e.code) {
    case FileError.QUOTA_EXCEEDED_ERR:
      msg = 'QUOTA_EXCEEDED_ERR';
      break;
    case FileError.NOT_FOUND_ERR:
      msg = 'NOT_FOUND_ERR';
      break;
    case FileError.SECURITY_ERR:
      msg = 'SECURITY_ERR';
      break;
    case FileError.INVALID_MODIFICATION_ERR:
      msg = 'INVALID_MODIFICATION_ERR';
      break;
    case FileError.INVALID_STATE_ERR:
      msg = 'INVALID_STATE_ERR';
      break;
    default:
      msg = 'Unknown Error';
      break;
  };

  console.log('Error: ' + msg);
}
window.webkitRequestFileSystem(window.TEMPORARY, 1024*1024, onInitFs, errorHandler);

推荐答案

如果写入成功，该文件将以chrome或chromium写入本地文件系统配置目录默认 - > 文件系统目录。

If the write was successful, the file would be written to local filesystem at chrome or chromium configuration directory at Default -> File System directory.
