java http接口传xml

实现Java HTTP接口传XML

流程步骤

首先，我们来看一下整件事情的流程。下面是实现Java HTTP接口传XML的步骤表格：

步骤	描述
步骤一	构建XML数据
步骤二	建立HTTP连接
步骤三	发送XML数据
步骤四	接收HTTP响应

代码示例

接下来，让我们一步步来实现吧！

步骤一：构建XML数据

// 创建一个XML文档对象
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.newDocument();

// 创建根节点
Element root = document.createElement("root");
document.appendChild(root);

// 创建子节点
Element child = document.createElement("child");
child.appendChild(document.createTextNode("Hello, World!"));
root.appendChild(child);

// 将XML转换为字符串
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(document), new StreamResult(writer));
String xmlString = writer.getBuffer().toString();

步骤二：建立HTTP连接

URL url = new URL("
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/xml");
connection.setDoOutput(true);

步骤三：发送XML数据

OutputStream outputStream = connection.getOutputStream();
outputStream.write(xmlString.getBytes());
outputStream.flush();

步骤四：接收HTTP响应

int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    String line;
    StringBuffer response = new StringBuffer();
    while ((line = reader.readLine()) != null) {
        response.append(line);
    }
    reader.close();
    System.out.println(response.toString());
} else {
    System.out.println("HTTP Error: " + responseCode);
}
