使用httpclient 調用selenium webdriver

時間 2019-11-06

標籤使用 httpclient 調用 selenium webdriver 欄目系統網絡简体版

原文原文鏈接

結合上次研究的selenium webdriver potocol ，本身寫http request調用remote driver代替selenium APIhtml

selenium web driver Json protocol 相關請看 http://www.cnblogs.com/tobecrazy/p/5020741.htmljava

我這裏使用的是Gson 和 httpclientweb

首先，起一個remote severchrome

 java -Dwebdriver.ie.driver="IEDriverServer.exe"   -Dwebdriver.chrome.driver="chromedriver.exe"  -jar selenium-server-standalone-2.48.0.jar

這裏要用到httpclient的Post 和delete methodapache

建立一個httpclient對象json

    HttpClient httpClient = HttpClients.createDefault();

建立一個post請求session

    JsonObject setCapability = new JsonObject();
        setCapability.addProperty("browserName","firefox");
        JsonObject capability = new JsonObject();
        capability.add("desiredCapabilities",setCapability);
        HttpPost httpPost = new HttpPost(base);

建立一個delete 請求app

     url = base + sessionId ;
         HttpDelete httpDelete = new HttpDelete(url);

從respose 中獲取session ID框架

HttpResponse response = httpClient.execute(httpPost);

		try {
			HttpEntity entity = response.getEntity();
			if (entity != null) {
				System.out.println("Response content length: "
						+ entity.getContentLength());

				String resultEntity = EntityUtils.toString(entity);
				System.out.println("Response content: " + resultEntity);
		        JsonObject result= new JsonParser().parse(resultEntity).getAsJsonObject();
		        JsonElement  sessionIdJson = result.get("sessionId");
		        if(!sessionIdJson.isJsonNull())
		        sessionId =sessionIdJson.getAsString();
		        JsonElement  valueJson = result.get("value");
		        
			 
				if(!valueJson.isJsonNull())
				{
					JsonObject tm=valueJson.getAsJsonObject();
					JsonElement elementIdJson = tm.get("ELEMENT");
					if(elementIdJson!=null)
					elementId=elementIdJson.getAsString();
				   
				}
			 

			}
		} finally {
			((Closeable) response).close();
		}

所有代碼以下：post
