使用wiremock模拟返回数据

       步骤如下：

　　1. 下载wiremock-body-transformer-1.1.3.jar及wiremock-standalone-2.3.1.jar

       2. 在__file文件中创建一个file，存放json格式的返回数据，内容如下

       cat __file/dsp.json

    }
  ],
  "id": "$(id)",
  "bidid": "1138050_182500_52476"
}

　　

       3. 设置mapping的json格式如下：

       cat mappings/test.json

       

{
    "request": {
        "url": "/api/dsp",
        "method": "POST"
    },
    "response": {
        "status": 200,
        "bodyFileName": "dsp.json",
        "headers": {
            "Content-Type": "text/xml; charset=utf-8"
        },
        "transformers": ["body-transformer"]
    }
}  

　　4.  运行脚本如下：

java -cp "wiremock-body-transformer-1.1.3.jar:wiremock-standalone-2.3.1.jar" com.github.tomakehurst.wiremock.standalone.WireMockServerRunner --extensions com.opentable.extension.BodyTransformer --port 9990

     5. 然后访问http://xxxx:9990/api/dsp即可得到2中的返回。
