Geoserver跨域解决方法
Geoserver跨域解决方法
参考来源：https://blog.csdn.net/GIS_Lyn/article/details/84744184
首先两种方式发布GeoServer，分别是Jetty与Tomcat
两种方式跨域 cross origin 解决方法不同，看完继续看第三种解决方法
方法1： Jetty发布的解决方法 自动安装的geoserver版本

方法2：Tomcat发布的Geoserver跨域解决方法
To add CORS headers, I simply added to $CATALINA_HOME/conf/web.xml the following lines:
/usr/tomcat/conf/web.xml设置添加参数如下：
CorsFilter
org.apache.catalina.filters.CorsFilter
cors.allowed.origins
http://localhost:8080,http://192.168.30.114:8888
cors.allowed.methods
GET,POST,HEAD,OPTIONS,PUT
cors.allowed.headers
Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers,Authorization
cors.exposed.headers
Access-Control-Allow-Origin,Access-Control-Allow-Credentials
cors.support.credentials
true
cors.preflight.maxage
10
CorsFilter

function Base64_Encode(str) {
var c1, c2, c3;
var base64EncodeChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
var i = 0, len = str.length, string = '';
while (i < len) {
c1 = str.charCodeAt(i++) & 0xff;
if (i === len) {
string += base64EncodeChars.charAt(c1 >> 2);
string += base64EncodeChars.charAt((c1 & 0x3) << 4);
string += "==";
break;
}
c2 = str.charCodeAt(i++);
if (i === len) {
string += base64EncodeChars.charAt(c1 >> 2);
string += base64EncodeChars.charAt(((c1 & 0x3) << 4) | ((c2 & 0xF0) >> 4));
string += base64EncodeChars.charAt((c2 & 0xF) << 2);
string += "=";
break;
}
c3 = str.charCodeAt(i++);
string += base64EncodeChars.charAt(c1 >> 2);

string += base64EncodeChars.charAt(c3 & 0x3F);
}
return string;
};
//geoserver服务rest api封装
function rest_gs_layers(gs_url,callback)

$.ajax({

},
success: function (c) {
if(callback) {
callback(c);
}
},
error: function (ex) {
alert(ex.responseText);
}
}
);
};
方法3：使用代理
自己写一个proxy.php,proxy.ashx,proxy.xxx
proxy.config
proxy.ashx 代理arcgis rest的方法
