小编j0n*_*ech的帖子

我正在使用PostgreSQL开发一个Node.js应用程序并在Heroku上托管.我的问题是我收到了如下身份验证错误:

14:32:05 web.1     | { [error: no pg_hba.conf entry for host "193.40.244.196", user "username", database "database_name", SSL off]

我需要在Spring Security conf中禁用缓存控制头.

根据文档,一个简单的http.headers.disable()应该这样做,但我仍然看到了

Cache-Control:no-cache, no-store, max-age=0, must-revalidate
Expires:0
Pragma:no-cache

回复中的标题.

我目前的安全配置是:

http.antMatcher("/myPath/**") // "myPath" is of course not the real path
    .headers().disable()
    .authorizeRequests()
     // ... abbreviated
    .anyRequest().authenticated();

到目前为止我尝试过的事情:

application.properties

我添加了这security.headers.cache=false条线,但没有区别.

使用过滤器

我尝试了以下过滤器:

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
  chain.doFilter(request, new HttpServletResponseWrapper((HttpServletResponse) response) {
      @Override
      public void setHeader(String name, String value) {
        if (name.equalsIgnoreCase("Cache-Control")) {
          value = "";
        } else if (name.equalsIgnoreCase("Expires")) {
          value = "";
        } else if …

我有一个对话框,里面有一个列表(TextView里面有一堆s LinearLayout)ScrollView.布局如下:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ProgressBar
        android:id="@+id/delete_progress"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:visibility="gone" />

    <ScrollView
        android:id="@+id/filename_scroll"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

        <LinearLayout
            android:id="@+id/filename_container"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
        </LinearLayout>
    </ScrollView>

    <View
        android:id="@+id/horisontal_separator"
        android:layout_width="fill_parent"
        android:layout_height="1dp"
        android:background="@android:color/darker_gray" />

    <LinearLayout
        android:id="@+id/button_container"
        android:layout_width="match_parent"
        android:layout_height="48dp" >

        <Button
            android:id="@+id/load_button"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:text="@string/button_load"
            android:gravity="center"
            android:layout_weight="1" />

        <View
            android:layout_width="1dp"
            android:layout_height="fill_parent"
            android:background="@android:color/darker_gray" />

        <Button
            android:id="@+id/delete_button"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:text="@string/button_delete"
            android:gravity="center"
            android:layout_weight="1" />
    </LinearLayout>

</LinearLayout>

它看起来像只有列表中的几个项目:

但是当屏幕上有更多东西可以放入时(实际需要滚动),我的按钮会被推到屏幕下方.当一直滚动到底部时,它看起来像这样:

我需要LinearLayout包含按钮作为页脚,它不应该滚动到任何地方,显然不会消失.我试图摆弄布局高度和重量,但无济于事.

我有一个显示评论的活动.注释本身有一个布局,所以我不能只使用ListView.

我用循环添加注释,程序遍历整个循环(通过LogCat检查),但只将第一个View(注释)添加到linearlayout.

我的代码(实际上fillComments参数将不是String []):

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.comment_layout);
    String[] comments = {"kommentaar 1", "kommentaar 2", "kommentaar 3"};
    mTitle = (TextView) findViewById(R.id.comments_title);
    mTextArea = (EditText) findViewById(R.id.comment_editor);
    mAddButton = (Button) findViewById(R.id.add_comment);
    mCommentArea = (LinearLayout) findViewById(R.id.comments_area);

    mTitle.setText(getIntent().getStringExtra("name"));
    fillComments(comments);
}

private void fillComments(String[] comments) {
    View comment;
    TextView commentator;
    TextView commentDate;
    TextView commentText;
    LayoutInflater inflater = getLayoutInflater();

    for (String s : comments) {
        Log.d("Comment adder", "Adding comment " + s);
        comment = inflater.inflate(R.layout.comment_row_layout, null);
        commentator = (TextView) comment.findViewById(R.id.commentator);
        commentDate = …

我正在使用node.js 的node-postgres模块,我在插入数据时遇到问题.

功能:

function addItems(listId, listItems, handle) {
    if (!listItems) {
        handle(listId);
        return;
    }
    var client = dbConnector.getClient(),
        important,
        dateArray,
        dateString,
        i,
        prepStatement;
    client.connect();
    for (i in listItems) {
        console.log(listItems[i]);
        dateArray = listItems[i].itemdate.split('-');
        dateString = dateArray[1] + '-' + dateArray[0] + '-' + dateArray[2];
        if (listItems[i].important) {
            important = 'true';
        } else {
            important = 'false';
        }
        prepStatement = {
            name: 'insert task',
            text: 'INSERT INTO listitem (todolist_id, name, deadline, description, important, done, created) VALUES ($1, $2, $3, …
