java - 如何使用 xml 正文调用 REST api

Question

我有一个用于登录的 REST api ( https://localhost/server/api/login )，它接受 xml 格式的参数，如下所示。

<?xml version="1.0" encoding="UTF-8" ?> 
<Request xmlns="http://www.xxxx.com/center/cbm/1.0.0">
  <Users>
    <User>
      <Type>userType</Type> 
      <Name>admin</Name> 
      <Password>password</Password> 
      <Captcha>On</Captcha> 
    </User>
   </Users>
 </Request>

如何使用 Java 调用它并接收响应。

Answer 1

您可以使用 Apache HTTP Client 4.x 执行 HTTP POST 请求:

String xmlString = "... your data ..."

HttpPost httpRequest = new HttpPost("https://localhost/server/api/login");
httpRequest.setEntity(new StringEntity(xmlString));

HttpClient httpclient = new DefaultHttpClient();
HttpResponse httpResponse = httpclient.execute(httpRequest, new BasicHttpContext());

if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK && httpResponse.getEntity() != null) {
  //handle response ok
} else {
  //handle error
}
