如何将数组（JSON数组）转换为Map？

2024-01-02

我的脚本返回一个数组（JSON 数组），如下所示：

[{redirectCount=0, encodedBodySize=60962, unloadEventEnd=0, responseEnd=1601.699999999255, domainLookupEnd=995.7999999896856, unloadEventStart=0, domContentLoadedEventStart=1970.3999999910593,

我需要打印Key / Pair值就像我从a打印的Map如下 ：

Map<String, ?> map = cap.asMap();
for ( Map.Entry<String, ?> entry : map.entrySet()) 
{
    System.out.println(entry.getKey() + " value is " + entry.getValue());
}

我尝试点击以下链接，但仍然没有成功：

  • 如何打印 json 对象和数组值？ https://stackoverflow.com/questions/23733020/how-can-i-print-json-objects-and-array-values
  • 如何将从控制器类返回的 JSON 数组打印到 jsp 页面 https://stackoverflow.com/questions/35501208/how-to-print-json-array-returned-from-controller-class-to-jsp-page
  • JSON - 迭代 JSONArray https://stackoverflow.com/questions/6697147/json-iterate-through-jsonarray

我收到的 JSON 格式是否可能与常规 JSON 格式不同？

我当前的代码基于Selenium它使用一个JavaScript读取性能统计信息如下：

String netData = ((JavascriptExecutor)driver).executeScript(scriptToExecute).toString();
System.out.println(netData);

JavaDocs of executeScript() https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/JavascriptExecutor.html#executeScript-java.lang.String-java.lang.Object...-提到以下内容：

如果脚本有返回值（即如果脚本包含 return 语句），则将执行以下步骤：

  • 对于 HTML 元素，此方法返回一个 WebElement
  • 对于小数，返回 Double
  • 对于非十进制数，返回 Long
  • 对于布尔值，返回一个布尔值
  • 对于所有其他情况，将返回一个字符串。
  • 对于数组，返回一个列表，其中每个对象都遵循上述规则。我们支持嵌套列表。
  • 对于映射，返回值遵循上述规则的映射。
  • 除非值为null或者没有返回值，其中返回null

对于不太复杂的 json，您可以尝试手动执行...

首先删除 { 和 [

jsontext = jsontext.replaceAll ("[\\[\\]{}]", "");

然后使用 , 分隔符分割 json 数组

String[] items = jsontext.split(",");

然后对于每个项目，使用 = 分隔符进行拆分，然后填充到数组中

Map<String, String> array;

for (String s: items){

    String[] item = s.split("=");
    if(item.length == 2){
        array.put(item[0].trim(), item[1].trim());
    }else{
        System.out.println("Error with: "+ s);
    }
}

如果你想 ？作为你的地图数组，那么你必须自己进行从 String 到 Int 的转换，等等......

对于更复杂的 json（数组中的数组等），您可能必须首先解析并保存内部数组，然后解析外部数组。
