java 接口自動化測試之數據請求的簡單封裝

      我們自己用java寫接口自動化測試框架或者做個接口自動化測試平台的話,是需要自己進行相關的請求的,因此我們需要簡單的封裝下httpclient,我新建了一個http工具類,將get方法和post方法進行了一個簡單的封裝。

     如果是開發的話,比如APP開發,無論是iOS還是Android,是需要將數據請求進行十分嚴密的封裝的,因為需要對各種網絡狀態,請求狀態做相應的判斷處理,因為需要通過這些判斷來做出相應的UI交互界面來給用戶提示,那么我們做接口測試的話是不需要這么嚴密的,因為測試的前提就是要保證測試環境的穩定,我們只考慮接口在正常的訪問下通過對傳參的各種控制來判斷接口是否做出了正確的數據傳輸。

     前幾篇已經記錄下了簡單的HTTPClient的get和post請求,下面是對它們進行了個簡單的封裝,使之更容易被我們使用

		connectionMgr.setDefaultMaxPerRoute(connectionMgr.getMaxTotal());

		return result;
	}

	public static String httpPost(String url,Map<String, Object>params)
	{
		HttpClient client = HttpClients.createDefault();
		String result = null;
		try {
			HttpPost post = new HttpPost(url);
			//添加post提交參數
			ArrayList<NameValuePair> pairList = new ArrayList<NameValuePair>();
		    for(Map.Entry<String, Object> entry:params.entrySet())
		    {
		    	NameValuePair pair = new BasicNameValuePair(entry.getKey(), entry.getValue().toString());
		    	pairList.add(pair);
		    }
		    
		    post.setEntity(new UrlEncodedFormEntity(pairList,"UTF-8"));
		    
		    HttpResponse response = client.execute(post);
		    //獲取狀態碼

			}
		    
		} catch (Exception e) {
            e.printStackTrace();

}

 做個簡單的測試:

               HttpUtil util = new HttpUtil();
		Map<String, Object> params = new HashMap<String, Object>();
		params.put("q", "good");
		params.put("salt", "1496238482428");
		params.put("sign", "02E15CDAF871B698FE04EE32FD2CF155");
		params.put("from", "en");
		params.put("appKey", "7743eee7f7e11d75");
		params.put("to", "zh-CHS");

		String result = util.httpPost(urlStr, params);
		System.out.println(result);

 輸出結果:

      如果不需要傳入參數,把第二個傳入的參數置為空即可,這只是簡單地封裝了下,在后續要寫的自動化測試框架我們可能還是要加入各種各樣的判斷以及日志輸出,畢竟測試最重要的還是斷言等這樣的測試結果。
