项目需求

项目中需要对影像作差值处理之后自动发布，自动发布就要生成xml或者json数据存入geoserver文件中，我刚开始以为放到文件夹中就可以，但是需要重新启动geoserver才可以，这样的话功能会就会显得很鸡肋，后来查看了网上的大神的资料才知道geoserver是有restapi，但是在使用过程中也遇到一些问题，最终功夫不负有心人，解决了相关问题，所以记录一下。

项目实现

geoserver的RESTAPI写的其实很清楚，就是发送请求接收请求即可。
代码是用python实现的，以生成发布栅格影像为例（其中包括增删查改内容）。
涉及到发布栅格影像那就包括对其中几个文件夹进行操作
workspace、coveragestore、coverage、layer
其中增加删除等先后顺序弄错的话，作者就在这里绕了半天，特别需要注意，其他倒没有什么难点。

代码实现

1、增加工作区（找到工作区相关API介绍）

 # TODO 查询指定工作区
    def getworkspaces(self):
        headers = {'Accept': 'application/xml'}
        response = requests.get('http://localhost:8080/geoserver/rest/workspaces/'+self.workspace,
                                auth=('admin', 'geoserver'), headers=headers)
        return response.status_code  # todo  查看工作区下的数据存储 
 # todo 新增工作区
    def addworkspace(self):  
        headers = {'content-type': 'application/xml'}
        response = requests.post(self.basicworkspaceurl,
                                 data=open('workspaces.xml').read(), auth=('admin', 'geoserver'), headers=headers)
        print(response.status_code)

其中workspaces.xml内容如下（包含的是你要增加的工作区名字）

<?xml version="1.0" encoding="UTF-8"?>
<workspace>
	<name>TheWaterQualityComparision</name>
</workspace>

2、增加coveragestore(找到coveragestore相关API介绍)

# 查看coveragestore,其中coveragename是其名字，还有指定其对应的工作区
  def getcoveragestore(self,coveragename):
        headers = {'Accept': 'application/xml'}
        response = requests.get('http://localhost:8080/geoserver/rest/workspaces/' + self.workspace+"/coveragestores/"+coveragename,
                                auth=('admin', 'geoserver'), headers=headers)
        return response.status_code  
 # 新增coveragestore,其中coveragename是其名字，还有指定其对应的工作区
    def addcoveragestroe(self,coveragestorepath): # TODO 新增coveragestore
        headers = {'content-type': 'application/xml'}
        response = requests.post(self.basicworkspaceurl+"/"+self.workspace+"/coveragestores",
                                 data=open(coveragestorepath+'/coveragestore.xml').read(), auth=('admin', 'geoserver'), headers=headers)
        print(response.status_code)

其中coveragestore.xml内容如下（name,描述，存储路径、工作区名字）

<?xml version="1.0" encoding="UTF-8"?>
<coverageStore>
  <name>20192929cha</name>
  <description>testapi2</description>
	<type>GeoTIFF</type>
	<enabled>true</enabled>
  <url>file://G:\Water_enviroment_Data\2016\2016_calss.tif\C\CHA.tif</url>
  <workspace>
		<name>TheWaterQualityComparision</name>  
  </workspace>
</coverageStore>

3、新增coverage(coverages的API)

 def addcoverage(self,coveragename,coveragepath):    #TODO 新增coverage
        headers = {'Accept': 'application/xml', 'content-type': 'application/xml'}
        url=self.basicworkspaceurl+"/"+self.workspace+"/coveragestores/"+coveragename+"/coverages"
        ps = requests.post(url=url, auth=('admin', 'geoserver'), data=open(coveragepath+'/coverage.xml').read(), headers=headers)
        return ps.status_code

其中coverages.xml内容如下（详情请查看官网）

<?xml version="1.0" encoding="UTF-8"?>
<coverage>
  <name>20192929cha</name>
  <nativeName>20192929cha</nativeName>

按照上述顺序执行完成之后，我们访问网站即可查看我们发布的数据。

4、关于删除发布的数据以及工作区
需要按照顺序执行，否则将会报错
删除工作区–>需要先删除工作区里面的数据存储内容。否则直接删除工作区删除不了（很重要）
要删除数据存储的内容，必须先删除数据存储里面的layer和coverage.必须具有优先级
workspace(coveragestore（layer\coverages）)

def deletelayer():  # TODO 删除layer
    headers = {'content-type': 'application/xml'}
    response = requests.delete(
        'http://localhost:8080/geoserver/rest/workspaces/TheWaterQualityComparision/layers/2016_2018CHA'
        , auth=('admin', 'geoserver'), headers=headers)
    print(response.status_code)
def  deletecovrerage():  # todo 删除coverages
    headers = {'content-type': 'application/xml'}
    response = requests.delete(
        'http://localhost:8080/geoserver/rest/workspaces/TheWaterQualityComparision/coveragestores/2016_2018TN/coverages/2016_2018CHA'
        , auth=('admin', 'geoserver'), headers=headers)
    print(response.status_code)
def deletecoverageStore(): # todo 删除coveragestore
    headers = {'content-type': 'application/xml'}
    response = requests.delete('http://localhost:8080/geoserver/rest/workspaces/TheWaterQualityComparision/coveragestores/2016_2018CHA'
                               , auth=('admin', 'geoserver'), headers=headers)
    print(response.status_code)
def deleteworkspace():   #TODO 删除工作区
    headers = {'content-type': 'application/xml'}
    response = requests.delete('http://localhost:8080/geoserver/rest/workspaces/TheWaterQualityComparision'
                            , auth=('admin', 'geoserver'), headers=headers)
    print(response.status_code)

5、关于geoserver样式设置
geoserver可支持SLD、CSS、YSLD、MBStyle四种方式定义Style。可查看官网进行学习
其中css需要下载相应插件进行安装

解压并复制到$GEOSERVER_HOME/webapps/geoserver/WEB-INF/lib目录重启GeoServer

在这里插入图片描述
具体可以查看网站学习css样式配置

同时也可以在Udig中配置好样式复制粘贴到geoserver样式设置中
