jmeter 与 json

1、添加一个 http信息头管理：

Add new value for Name = “Content-Type” and value = “application/json” (without quotes).

2、增加一个http sample ：

使用body data进行json格式数据请求

3、json响应内容截取：

a、增加一个 BSF POSTPROCESSOR选择js语言，script内容如下：

// Turn the JSON into an object called 'SearchResponse'
eval('var SearchResponse = ' + prev.getResponseDataAsString());

// Create a variable called haveBoots_# containing the number of matching URLs
// For Each Result
//     Create a variable called haveBoots and assign it the URL
vars.put("haveBoots_#", SearchResponse.responseData.results.length);

for (var counter = 1; counter <= SearchResponse.responseData.results.length; counter++)
{
    var x = SearchResponse.responseData.results[counter - 1];

   // haveBoots = theUrl
   vars.put("haveBoots" + counter, x.unescapedUrl);
}

b、增加一个 BEANSHELL POSTPROCESSOR  

import org.json.JSONArray;
import org.json.JSONObject;

String jsonString = prev.getResponseDataAsString();
JSONArray equipmentParts = new JSONArray(jsonString);
JSONArray parts = new JSONArray();

for(int i=0;i<equipmentParts.length();i++ ){
    JSONObject equipmentPart = equipmentParts.getJSONObject(i).getJSONObject("equipmentPart");
    JSONObject allAttributes = equipmentPart.getJSONObject("allAttributes");
    JSONObject part = new JSONObject();
    part.put("partId",allAttributes.getLong("equipmentPartId"));
    part.put("partNumber",allAttributes.getString("compositePartName"));
    // add more here
    parts.put(part);
}

vars.put("jsonResponse", parts.toString());后续直接使用  ${jsonResponse}即可

c、增加一个正则表达提取器 

下面再增加一个 foreach控制器，将 books的变量传递到bookname变量中，在http请求中使用${bookname}即可
