HttpClient做接口测试时自定义参数长度

在做http接口测试的时候，老是要做一大堆的参数和值，整个界面看着相当别扭，于是就把参数部分组合放到一个方法中，把执行放到一个方法中，主函数就只要获取response字符串做处理做断言就好了，这样这个代码看上去清爽多了，这里用到了httpclient、dom4j、testng的jar包。

private static String[][] keyVlaueList = {{"cdkey","6SDK"},{"password","160489"}}; //根据需要自定义接口参数个数及参数值

private static List<NameValuePair> postPara = new ArrayList<NameValuePair>();

private static String responseEntiy;

        /**

*/

public static List<NameValuePair> getPostPara(String[][] keyVlaueList) throws DocumentException{

for(int i = 0;i<keyVlaueList.length;i++)

{

postPara.add(new BasicNameValuePair(keyVlaueList[i][0],keyVlaueList[i][1]));

}

return postPara;

CloseableHttpClient httpclient = HttpClients.createDefault();

post.setEntity(new UrlEncodedFormEntity(postPara));

responseEntiy = EntityUtils.toString(entiyResponse).trim();

responseEntiy = getResponse(url);

//获取的字符串：responseEntiy = <?xml version="1.0" encoding="UTF-8"?><response><error>0</error><message>1442.4</message></response>

//根据接口返回的字符类型做相应的解析，自由发挥！

try {

Document document = DocumentHelper.parseText(responseEntiy);

Element rootElement = document.getRootElement();  

Element nodeElement = rootElement.element("error");

String errorString = nodeElement.getTextTrim();

   if (!errorString.equals("0")){

    AssertJUnit.fail(responseEntiy);

   }

}catch (DocumentException e) {

e.printStackTrace();

}

}
