WebDriver之JsonWireProtocol

WebDriver之JsonWireProtocol###

JsonWireProtocol说明
JsonWireProtocol(以下简称JWP)是通过使用webdriver与remote server进行通信的web service 协议。通过http请求，完成和remote server的交互。

交互过程
下面，我将列出一系列http请求，利用JSP和remote server进行通信，来进行浏览器操作。（注：书写格式为：GET URL 参数）

1. 打开浏览器
即，创建一个新的browser session。
POST http://10.236.122.10:4444/wd/hub/session
{desiredCapabilities:{browserName: 'chrome' }}
结果返回：

{
"status": 0,
"sessionId": "277e823a-8be2-48eb-9001-971cc1bff9c4",
"state": null,
"value": {
"platform": "XP",
"acceptSslCerts": true,
"javascriptEnabled": true,
"browserName": "chrome",
"chrome": {
"userDataDir": "C:\Users\GUOLIA~1\AppData\Local\Temp\scoped_dir4600_564"
},
"rotatable": false,
"locationContextEnabled": true,
"webdriver.remote.sessionid": "277e823a-8be2-48eb-9001-971cc1bff9c4",
"version": "41.0.2272.118",
"takesHeapSnapshot": true,
"cssSelectorsEnabled": true,
"databaseEnabled": false,
"handlesAlerts": true,
"browserConnectionEnabled": false,
"nativeEvents": true,
"webStorageEnabled": true,
"applicationCacheEnabled": false,
"takesScreenshot": true
},
"class": "org.openqa.selenium.remote.Response",
"hCode": 28232762
}

记住上面返回的
"sessionId": "277e823a-8be2-48eb-9001-971cc1bff9c4"
2. 打开一个url
比如，打开百度首页：

POST
http://10.236.122.10:4444/wd/hub/session/277e823a-8be2-48eb-9001-971cc1bff9c4/url
{url :'http://www.baidu.com' }

3. 查找输入框

POST
http://10.236.122.10:4444/wd/hub/session/277e823a-8be2-48eb-9001-971cc1bff9c4/elements
{using:'css selector',value:'#kw'}

返回：
{
"status": 0,
"sessionId": "b6d34570-8300-4507-b60c-ab7cd1fe6536",
"state": "success",
"value": [
{
"ELEMENT": "0"
}
],
"class": "org.openqa.selenium.remote.Response",
"hCode": 30641031
}
记住返回值， 下面要用。
"ELEMENT": "0"
4. 输入元素

POST
http://10.236.122.10:4444/wd/hub/session/277e823a-8be2-48eb-9001-971cc1bff9c4/element/0/value
{value:[hello,world]}

*** 5. 查找OK按钮***
http://10.236.122.10:4444/wd/hub/session/277e823a-8be2-48eb-9001-971cc1bff9c4/elements
{using:'css selector',value:'#su'}
4. 点击OK
http://10.236.122.10:4444/wd/hub/session/277e823a-8be2-48eb-9001-971cc1bff9c4/element/1/click

返回点击成功了：
{
"status": 0,
"sessionId": "277e823a-8be2-48eb-9001-971cc1bff9c4",
"state": "success",
"value": null,
"class": "org.openqa.selenium.remote.Response",
"hCode": 11068806
