從JSON響應中提取和處理

Question

我正在通過輸入酒店名稱進行酒店搜索.Below是有效的JSON響應。這是一家酒店搜索的迴應。我已經運行了15個線程，並且針對與此類似的不同酒店，我還有14個JSON響應。在這個迴應中，您可以看到提供者使用數組值的「提供者」和「結果」。我的要求是找出有多少優惠，即每家提供商共有15家酒店。

Answer 1

以下是BeanShell的代碼：

import java.util.HashMap; 
import java.util.Map; 

results_count = Integer.parseInt(vars.get("results_matchNr")); 
providers_count = Integer.parseInt(vars.get("providers_matchNr")); 
log.info("total results " + results_count); 
Map results = new HashMap(); 
Map providers = new HashMap(); 

for(i=1; i<=providers_count; i++){ 
    log.info("iteration " + i); 
    temp = vars.get("providers_"+i); 
    log.info("provider_name " + temp); 
    providers.put(i-1, temp); 
} 
log.info("providers: " + providers); 

int provider_index = -1; 
String provider_name = ""; 

for(i=1; i<=results_count; i++){ 
    log.info("iteration " + i); 
    provider_index = Integer.parseInt(vars.get("results_"+i)); 
    log.info("provider_index " + provider_index); 
    provider_name = providers.get(provider_index); 
    log.info("provider name :" + provider_name); 
    if(results.get(provider_name) == null){ 
     log.info("ading key for the first time " + provider_name); 
     results.put(provider_name, 1); 
    } 
    else{ 
     log.info("second time " + provider_name); 
     int existing = results.get(provider_name); 
     log.info("exisiting value " + existing); 
     int updateValue = existing+1; 
     log.info("updated value: " + updateValue); 
     results.put(provider_name, updateValue); 
    } 
} 

log.info("results-providers mapping " + results); 

int threadNum = ctx.getThreadNum(); 

// if you want to log something to jmeter.log file 

// Pass true if you want to append to existing file othewise false. 
f = new FileOutputStream("G:\\naveen\\mywork\\testing\\performance\\tools\\jmeter\\examples\\result.csv", true); 
p = new PrintStream(f); 
this.interpreter.setOut(p); 
String output = "thread number#" + threadNum + " " + results; 
print(output); 
f.close(); 

添加BeanShell的後處理器採樣，並添加上面的代碼。

添加JSONPATH提取得到的提供商，並添加以下語法：

$.providers[*].name 

添加另一個JSONPATH提取得到的結果/報價，並添加以下語法：

$.results[*].providerIndex 

注意：更改文件位置以根據您的機器在beanshell代碼中存儲結果。

以下是將被保存到文件中的結果：

thread number#0 {Expedia.dk=1, Agoda.com=2, Hotels.com=1, getaroom.com=1} 
thread number#1 {Expedia.dk=1, Agoda.com=2, Hotels.com=1, getaroom.com=1} 

//兩行兩個線程。在這裏，Agoda.com提供商有兩個優惠，所以計數是2，剩下的提供商每個都有一個優惠。

說明：驗證了2個用戶的腳本。結果文件中會出現兩個條目（一個線程 - >一行）。根據您對beanshell代碼（與文件編寫相關的代碼）的要求來調整窗口。
