概述

GIS是对于我来说是一个全新的，没有接触过的东西，需求是，需要往GeoServer中添加一个要素，如何做呐？

解决

网上的解决方案，大多如下图，可是自己试着做的时候，发现大多仍旧存在很多问题
在这里插入图片描述

点开GML看到了其中的数据类型
在这里插入图片描述

如下图1:

看到一篇帖子后将xml做如下构造:

需要注意的是，
INSERT标签下的第一个标签为图层名，xmlns对应工作区
在这里插入图片描述

而geom对应图层中的geom
在这里插入图片描述
Polist从图1拿

结果:

请求xml和结果xml

总结一下，由于Geoserver及Gis一套是完全新的、没接触过的东西，为此，在构建的时候，遇到大多问题，都是新知识的问题，不知道这个是什么，不知道要怎么做，只能盲目的搬抄网上案例，回过头来看，从网上案例也可知道，它就是生成一个xml发送给geoserver的过程，那么这样的话，也就不用一开始浪费大量的时间，一直在写前端代码，使用postman发送请求不就可以了嘛？这是第一个问题，第二个是面对新东西的时候，不愿意去一点一点的看它，比如一开始就没有去分析图层的GML，从某种程度来说，新的知识领域是相互对应和映照的，为此一点点的看、一点点分析其意义是必要的，也是应该的，这样才能解决你想解决的问题
