Question

我的项目列表中包含迷你地图的生成地点。地图上应该有2个点，并且这两个点之间有彩色的道路方向。

它应该看起来像这样：

这应该是静态图像，因为页面上会有许多不同方向的图片。但正如我所见，谷歌静态地图并不允许绘制这样的图像。两点之间只能有直线，如下所示：

但我需要指导......

我决定使用静态地图，因为在我的网络应用程序中，我收到了这两点的坐标，如果我使用静态地图，很容易将它作为变量放在我的PHP模板中。但是有可能以同样的方式接收静态图像的方向吗？

我找到了很少使用JavaScript API的解决方案，但是没有找到如何根据需要绘制静态图像...

Answer 1

您可以分两步完成。

从PHP代码执行指令请求以获取编码折线
使用步骤1中的编码折线与静态地图

E.g。

https://maps.googleapis.com/maps/api/directions/json?origin=Grodno&destination=Minsk&mode=driving&key=YOUR_API_KEY

这将在路线[0] - ＆gt; overview_polyline-＆gt; points

现在在静态地图中使用折线：

我为我的网站创建了一个小实用程序功能，可以完全满足您的需求：https://github.com/bdupiol/php-google-static-map-directions

给定原点，目的地和一系列航点（如果需要），它会为您提供干净的Google静态地图网址，并在这些点之间呈现行车路径，并设置正确的标记。

<强>的index.php

<?php

include "static-map-direction.php";

$origin = "45.291002,-0.868131";
$destination = "44.683159,-0.405704";
$waypoints = array(
    "44.8765065,-0.4444849",
    "44.8843778,-0.1368667"
  );

$map_url = getStaticGmapURLForDirection($origin, $destination, $waypoints);

echo '<img src="'.$map_url.'"/>';

我在PHP中使用Bedu33逻辑并在javascript中编写它以生成Google Maps静态图像，以防有人像我一样需要它。此代码使用iText-image-to-pdf

的响应

var request = directionsDisplay.directions.request;
var start = request.origin.lat() + ',' + request.origin.lng();
var end = request.destination.lat() + ',' + request.destination.lng();
var path = directionsDisplay.directions.routes[0].overview_polyline;
var markers = [];           
var waypoints_labels = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K"];
var waypoints_label_iter = 0;   
markers.push("markers=color:green|label:" + waypoints_labels[waypoints_label_iter] + '|' + start);

for(var i=0;i<request.waypoints.length;i++){
    //I have waypoints that are not stopovers I dont want to display them
    if(request.waypoints[i].stopover==true){
        markers.push("markers=color:blue|label:" + waypoints_labels[++waypoints_label_iter] + '|' + request.waypoints[i].location.lat() + "," +request.waypoints[i].location.lng());
    }           
}

markers.push("markers=color:red|label:" + waypoints_labels[++waypoints_label_iter] + '|' + end);

markers = markers.join('&');

alert("https://maps.googleapis.com/maps/api/staticmap?size=1000x1000&maptype=roadmap&path=enc:" + path + "&" + markers);

我今天一直在使用从距离矩阵返回的overview_polyline进行此操作，但是在某些情况下，将多义线添加到静态地图时不会在静态地图上绘制该多义线，但是在动态地图。随着Google的新定价的到来，我们不得不进行更改，因为我们当前的年付款额将另外增加1500％。静态地图的好处是您可以传递邮政编码/邮政编码和完整地址。您还可以传入变量，这使事情变得容易。
