大家好,又见面了,我是你们的朋友全栈君。
我有这个InputStream:
InputStream inputStream = new ByteArrayInputStream(myString.getBytes(StandardCharsets.UTF_8));
如何将其转换为ServletInputStream?
我努力了:
ServletInputStream servletInputStream = (ServletInputStream) inputStream;
但不起作用。
编辑:
我的方法是这样的:
private static class LowerCaseRequest extends HttpServletRequestWrapper {
public LowerCaseRequest(final HttpServletRequest request) throws IOException, ServletException {
super(request);
}
@Override
public ServletInputStream getInputStream() throws IOException {
ServletInputStream servletInputStream;
StringBuilder jb = new StringBuilder();
String line;
String toLowerCase = “”;
BufferedReader reader = new BufferedReader(new InputStreamReader(super.getInputStream()));
while ((line = reader.readLine()) != null) {
toLowerCase = jb.append(line).toString().toLowerCase();
}
InputStream inputStream = new ByteArrayInputStream(toLowerCase.getBytes(StandardCharsets.UTF_8));
servletInputStream = (ServletInputStream) inputStream;
return servletInputStream;
}
}
我正在尝试将所有请求都转换为小写。
