【中文标题】Java HttpResponse 提取数据【英文标题】：Java HttpResponse Extract data 【发布时间】：2021-12-23 11:36:26 【问题描述】：我有一个 java 代码。此代码执行 http 请求并获得响应。响应返回了多个对象。我想创建一个 Map
每个地图实例将存储一个对象。我如何处理响应并存储在地图的数组列表中
这是我的代码

</soap:Envelope>我想将每个“结果”映射到一张地图。所以在这种情况下 ArrayList 将包含 13 个地图。第一张地图将是 地图1 "ID":"510004255", "客户密钥":"ffsdfsfdsf" ...
我应该如何处理响应以创建这样的地图列表
【问题讨论】：
【参考方案1】：我能够使用文档构建器和解析响应正文来解决问题。
if(response.getStatus()==200)
ArrayList<Map<String,String>> BU_Data = new ArrayList<Map<String,String>>();
DocumentBuilderFactory factory = DocumentBuilderFactory.newDefaultInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document res = builder.parse(new InputSource(new StringReader(response.getBody())));
NodeList resultList = res.getElementsByTagName("Results");
for(int i=0;i<resultList.getLength();i++)
Node p = resultList.item(i);
if(p.getNodeType()==Node.ELEMENT_NODE)
Element BU_Info = (Element) p;
NodeList ResultList = BU_Info.getChildNodes();
for(int j=0;j<ResultList.getLength();j++)
Node n = ResultList.item(j);
if(n.getNodeType()==Node.ELEMENT_NODE)
Element Result_Value = (Element) n;
System.out.println(Result_Value.getTagName()+" "+Result_Value.getTextContent());
System.out.println("------------------");
一个重要的事情是builder.parse。它需要一个 Inputsource 和字符串阅读器。如果你不使用它，你可能会得到格式错误的 URL 异常
