如何将数组(JSON数组)转换为Map? [英] How to convert a Array (JSON Array) to Map?

问题描述

我的脚本向我返回了一个数组(JSON数组)，如下所示:

My script returns me a Array (JSON Array) as follows :

我需要打印 Key / Pair 值，就像我从 Map 中进行打印一样，如下所示:

I need to print the Key / Pair values just like I print from a Map as follows :

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

我尝试遵循以下链接，但仍然没有成功:

I have tried to follow the following links but still no success:

• 如何打印JSON数组从控制器类返回到jsp页面
• JSON-遍历JSONArray

• How can i print json objects and array values?

我接收到的JSON格式是否可能与常规JSON格式不同?

Is it possible the JSON format I am recieving is different from the regular JSON formats?

我当前的代码基于 Selenium ，后者使用 Javascript 读取性能统计信息，如下所示:

My current code is based on Selenium which uses a Javascript to read the performance statistics as follows :

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

href ="https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/JavascriptExecutor.html#executeScript-java.lang的

JavaDocs .String-java.lang.Object ...-"rel =" nofollow noreferrer> executeScript() 提到以下内容:

JavaDocs of executeScript() mentions the following :

如果脚本具有返回值(即，如果脚本包含return语句)，则将执行以下步骤:

If the script has a return value (i.e. if the script contains a return statement), then the following steps will be taken:

• 对于HTML元素，此方法返回一个WebElement
• 对于小数，返回一个Double
• 对于非十进制数字，将返回Long
• 对于布尔值，返回布尔值
• 对于所有其他情况，将返回一个字符串.
• 对于数组，请按照上面的规则返回一个列表，其中包含每个对象.我们支持嵌套列表.
• 对于地图，请返回一个具有遵循上述规则的值的地图.
• 除非该值为null或不存在返回null的返回值，否则

推荐答案

对于不太复杂的json，您可以尝试手动执行...

for not so complicated jsons, you can try doing it manually...

先删除{和[

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

然后使用，分隔符分割json数组

then split the json array using the , separator

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

然后针对每个项目，使用=分隔符进行拆分，然后填充到您的数组中

then for each item, split using the = separator, and then populate into your array

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);
    }
}

如果要?作为您的地图数组，那么您必须自己进行从String到Int等的转换...

if you want ? as your map array, then you have to do your own conversion from String to Int, etc...

对于更复杂的json(数组中的数组等)，您可能必须先解析并保存内部数组，然后再解析外部数组.

for more complicated jsons (arrays within arrays, etc), you may have to resolve and save the inner arrays first, then resolve the outer arrays.
