我有最新的docker安装(没有boot2docker),我无法连接到本地运行的dockerized redis实例.你能告诉我这里我做错了什么吗？
创建了docker,将端口6379映射到127.0.0.1:6379
bash-3.2$ docker run -p 127.0.0.1:6379:6379 --name webmonitor-redis -d redis
3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9
docker ps输出:
bash-3.2$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3291541d58ab redis "/entrypoint.sh redis" 14 seconds ago Up 6 seconds 127.0.0.1:6379->6379/tcp webmonitor-redis
尝试从外部容器(但运行容器的同一主机)连接,连接失败:
bash-3.2$ ./src/redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> exit
如果我尝试从另一个容器连接,它可以工作..
bash-3.2$ docker run -it --link webmonitor-redis:redis --rm redis sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'
172.17.0.8:6379>
这是docker检查容器:
bash-3.2$ docker inspect 3291541d58ab

我目前正在寻找一种解决方案来选择(或突出显示)OpenLayers.Layer.Vector中的向量.
我已经构建了一个简单的网格表,用户可以在其中选择一个向量(以WKT格式的字符串给出),该向量应突出显示图层上的相应向量.当用户访问网站时,网格表中的所有向量都将绘制到地图上的矢量图层.
我发现我需要OpenLayers.Control.ModifyFeature的selectFeature(feature)函数或者OpenLayers.Control.SelectFeature(参见dev.openlayers.org/apidocs/files/OpenLayers/Control/SelectFeature-js.html的select(功能(可能不存在或不再存在？).请参阅邮件列表中的帖子:osgeo-org.1803224.n2.nabble.com/Programatically-Select-a-Feature-tt2192485.html# a2193928更多信息.
我尝试了以下但没有成功,所以我希望有人可以抓住这些代码行,并可以向我展示一个有效的代码片段;-)
// ... some initializing code
this.vlayer = new OpenLayers.Layer.Vector("VectorLayer"); // VectorLayer
// some controls
this.openLayerControlPoint = new OpenLayers.Control.DrawFeature(this.vlayer, OpenLayers.Handler.Point);
this.openLayerControlPolygon = new OpenLayers.Control.DrawFeature(this.vlayer, OpenLayers.Handler.Polygon);
this.openLayerControlModify = new OpenLayers.Control.ModifyFeature(this.vlayer, {
mode: OpenLayers.Control.ModifyFeature.RESHAPE | OpenLayers.Control.ModifyFeature.DRAG,
standalone: false
});
// just deactivate to make sure everything is really deactivated
this.openLayerControlPoint.deactivate();
this.openLayerControlPolygon.deactivate();
this.openLayerControlModify.deactivate();
// add the just created layer to the map
this.map.addLayer(this.vlayer);
// add all (deactivated) controls to the map
this.map.addControl(this.openLayerControlPoint);
this.map.addControl(this.openLayerControlPolygon);
this.map.addControl(this.openLayerControlModify);

我正在调试下面的问题,并发布我正在调试和处理的解决方案,解决方案或类似的问题发布在几个论坛上,但我认为解决方案有一个错误,当num [0] = 0或一般num [x] = x？我对么？如果我错了,请随时纠正我.
给定包含n + 1个整数的数组nums,其中每个整数在1和n之间(包括1和n),证明必须存在至少一个重复的数字.假设只有一个重复的数字,找到重复的数字.
注意:您不能修改数组(假设该数组是只读的).您必须仅使用常量O(1)额外空间.您的运行时复杂度应小于O(n2).数组中只有一个重复的数字,但它可以重复多次.
int findDuplicate3(vector<int>& nums)
{
if (nums.size() > 1)
{
int slow = nums[0];
int fast = nums[nums[0]];
while (slow != fast)
{
slow = nums[slow];
fast = nums[nums[fast]];
}
fast = 0;
while (fast != slow)
{
fast = nums[fast];
slow = nums[slow];
}
return slow;
}
return -1;
}
我想在openlayers 2.13中使用cubiccurve,并且我已经添加了必要的文件,但是绘制时绘制的是线而不是曲线.
文件可在网站上找到:http://trac.osgeo.org/openlayers/ticket/1715#no1
绘制曲线对我们来说非常重要,我无法控制自己的曲线.
可以帮助我吗？
有谁知道这个错误是什么？
