篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了LoadRunner如何对GIS服务器进行性能测试相关的知识，希望对你有一定的参考价值。
1、需求了解
首先确定对gis服务器压测的测试范围，形成具体的测试用例，gis平台都是通过网页端的javascript api调用的gis集群服务接口，通过LR录制上一步中的业务操作，找到javascript向gis服务器请求的地址做参数化后形成压测脚本，实现对GIS服务器的压力测试。
2、测试范围
ARCGIS性能测试主要范围有三个：ARCGIS生成基础地图服务、空间查询服务、为地图提供数据的服务接口的性能,本文主要对ARCGIS生成基础地图服务性能测试进行介绍。
3、测试工具
LoadRunner 11
4、测试步骤
4.1脚本准备
利用loadrunner对地图查询业务进行录制，录制脚本如下：
1 Action() 2 { 3 lr_start_transaction("查询"); 4 5 web_custom_request("0_4", 6 "URL=http://xxx.xx.x.xxx:xxxx/arcgis/rest/services/xxx/{服务名称}/MapServer/0?f=json", 7 "Method=GET", 8 "Resource=0", 9 "Referer=http://xxx.xx.x.xxx:xxxx/xxxgis/aigis/map.html?module=%E4%B8%9A%E5%8A%A1%E5%88%86%E5%B8%83", 10 "Mode=HTML", 11 "EncType=application/x-www-form-urlencoded", 12 EXTRARES, 13 "Url=0?f=json", "Referer=http://xxx.xx.x.xxx:xxxx/xxxgis/aigis/map.html?module=%E4%B8%9A%E5%8A%A1%E5%88%86%E5%B8%83", ENDITEM, 14 LAST);

其中主要参数为服务名称、行政代码和geometry，服务名称为系统中的行政区划服务，包括AdminProvince（省级）、AdminDistrict（市级）与AdminCounty（县级）等；where=CODE+like+%{查询地区行政区划码}%25%27（根据具体项目决定）；geometry代表空间查询使用的几何要素。
