将中文文件名重命名为 jarsigner 程序支持的文件名
将文件名按 UTF-8 编码进行 URL 编码。

$encodename = urlencode(iconv('GB2312','UTF-8',$filename));

判断是否和原来的文件名相同

if ($encodename !== $filename) {

如果不相同则重命名

rename($argv[1] . DIRECTORY_SEPARATOR . $filename, $argv[1] . DIRECTORY_SEPARATOR . $encodename);

完整 rename.php 源代码如下

    <?php
    foreach(scandir($argv[1]) as $filename) {
    $encodename = urlencode(iconv('GB2312','UTF-8',$filename));
    if ($encodename !== $filename) {
    rename($argv[1] . DIRECTORY_SEPARATOR . $filename, $argv[1] . DIRECTORY_SEPARATOR . $encodename);
    echo 'rename ' . $filename . ' to ' . $encodename . "
";
    }
    }
    ?>

在程序中将请求还原成相应的文件名
确定需要判断的路径

String urlprefix = "file:///android_asset/www/";

判断当前请求是否属于该路径

if (url.startsWith(urlprefix)) {

属于该路径时，判断当前请求是否包含参数

if (url.contains("?") || url.contains("#")) {

获取文件路径

String relativePath = "www/" + url.substring(urlprefix.length());

尝试按路径打开文件

stream = cordova.getActivity().getAssets().open(relativePath);

不能打开文件时，返回异常信息作为文件内容

    StringWriter stringWriter = new StringWriter();
    PrintWriter printWriter = new PrintWriter(stringWriter, true);
    e.printStackTrace(printWriter);
    byte[] bytes = new byte[0];
    try {
    bytes = stringWriter.toString().getBytes("UTF-8");
    } catch (UnsupportedEncodingException e2) {
    e2.printStackTrace();
    }
    stream = new ByteArrayInputStream(bytes);

获取文件的 MIME 类型

String mimetype = FileHelper.getMimeType(url, cordova);

返回该文件

return new WebResourceResponse(mimetype, "UTF-8", stream);

完整 UrlFilter.java 源代码如下

    public WebResourceResponse shouldInterceptRequest(String url) {
    String urlprefix = "file:///android_asset/www/";
    if (url.startsWith(urlprefix)) {
    if (url.contains("?") || url.contains("#")) {
    return super.shouldInterceptRequest(url);
    } else {
    String relativePath = "www/" + url.substring(urlprefix.length());
    InputStream stream;
    try {
    stream = cordova.getActivity().getAssets().open(relativePath);
    } catch (IOException e) {
    StringWriter stringWriter = new StringWriter();
    PrintWriter printWriter = new PrintWriter(stringWriter, true);
    e.printStackTrace(printWriter);
    byte[] bytes = new byte[0];
    try {
    bytes = stringWriter.toString().getBytes("UTF-8");
    } catch (UnsupportedEncodingException e2) {
    e2.printStackTrace();
    }
    stream = new ByteArrayInputStream(bytes);
    }
    String mimetype = FileHelper.getMimeType(url, cordova);
    return new WebResourceResponse(mimetype, "UTF-8", stream);
    }
    } else {
    return super.shouldInterceptRequest(url);
    }
    }
