要在Android HTTP服务器中使用外部脚本,可以使用Android的Asset Manager将外部脚本文件作为资源添加到项目中,然后将其输出到客户端。以下是一个示例,其中使用Asset Manager加载JavaScript文件并在HTTP响应中输出:
private void serveScriptFile(HttpRequest request, HttpResponse response) throws IOException {
AssetManager assetManager = getAssets();
InputStream inputStream = null;
OutputStream outputStream = null;
try {
inputStream = assetManager.open("script.js");
response.setResponseCode(HttpResponse.HTTP_OK);
response.setHeader("Content-Type", "text/javascript");
outputStream = response.getOutputStream();
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, bytesRead);
}
} catch (IOException e) {
response.setResponseCode(HttpResponse.HTTP_NOT_FOUND);
outputStream.write("File not found".getBytes());
} finally {
if (inputStream != null) inputStream.close();
if (outputStream != null) outputStream.close();
}
}
请注意,此代码假定您的外部脚本文件名为“script.js”,并将其放在您的项目的“assets”文件夹中。在客户端请求调用“serveScriptFile”方法时,它将输出“script.js”文件的内容作为HTTP响应。
