当选择语言为中文时，当登录用户账号密码不符时，跳转到http://*******/login页面，无任何内容显示。
语言为英文时，出错信息正常：
需要修改源码2个文件：
1.appinventor-sources\appinventor\appengine\war\login.jsp
<center><p><a href="/login/sendlink" style="text-decoration:none;">${passwordclickhereLabel}</a></p></center>
修改为：
<center><p><a href="/login/sendlink?locale=<%= locale %>" style="text-decoration:none;">${passwordclickhereLabel}</a></p></center>
2.appinventor-sources\appinventor\appengine\src\com\google\appinventor\server\LoginServlet.java
1.修改调用 fail()，大概有11处。
fail(req, resp, ************);
修改为：
fail(req, resp, locale,**********);
2.修改 fail()函数，1处
private void fail(HttpServletRequest req, HttpServletResponse resp, String error) throws IOException {
resp.sendRedirect("/login/?error=" + sanitizer.sanitize(error));
return;
}修改为：
private void fail(HttpServletRequest req, HttpServletResponse resp,String locale, String error) throws IOException {
resp.sendRedirect("/login/?locale="+ locale +"&error=" + URLEncoder.encode(sanitizer.sanitize(error)));
return;
}3.修改sendlink页面
} else if (page.equals("sendlink")) {
out = setCookieOutput(userInfo, resp);
out.println("<head><title>" + bundle.getString("requestreset") + "</title></head>\n");
out.println("<body>\n");
out.println("<h1>" + bundle.getString("requestlink") + "</h1>\n");
out.println("<p>" + bundle.getString("requestinstructions") + "</p>\n");
out.println("<form method=POST action=\"" + req.getRequestURI() + "\">\n");
out.println(bundle.getString("enteremailaddress") + ": <input type=text name=email value=\"\" size=\"35\"><br />\n");
out.println("<p></p>");
out.println("<input type=submit value=\"" + bundle.getString("sendlink") + "\" style=\"font-size: 300%;\">\n");
out.println("</form>\n");
return;
}替换为：
} else if (page.equals("sendlink")) {
out = setCookieOutput(userInfo, resp);
out.println("<head><title>" + bundle.getString("requestreset") + "</title></head>\n");
out.println("<body>\n");
out.println("<h1>" + bundle.getString("requestlink") + "</h1>\n");
out.println("<p>" + bundle.getString("requestinstructions") + "</p>\n");
out.println("<form method=POST action=\"" + req.getRequestURI() + "\">\n");
out.println(bundle.getString("enteremailaddress") + ": <input type=text name=email value=\"\" size=\"35\"><br />\n");
out.println("<p><input type=hidden name=locale value=\""+ locale + "\"></p>");
out.println("<input type=submit value=\"" + bundle.getString("sendlink") + "\" style=\"font-size: 300%;\">\n");
out.println("</form>\n");
return;
}4.linksent加上语言
resp.sendRedirect("/login/linksent/");
替换为：
resp.sendRedirect("/login/linksent/?locale=" + locale);
