问题描述
目标概述：(1) 将 XML 文件保存到 IntelliJ 中的字符串元素 (2) 将请求 XML 发送到 http 端点 (3) 从 http 端点获取响应 XML>
到目前为止，我已经能够读取 XML 响应，但在尝试发送请求时不断收到错误消息。我的工作方法没有实现 REST 方法，但更愿意在我的项目中使用这些方法。由于我仍在学习，因此这是一种基本的方法，因此非常感谢任何提示。想更近些
到目前为止，我的尝试是将 xml 请求设置为要发送到端点的字符串，然后从同一端点读取响应。下面是我尝试过的代码，它尚未严重依赖 REST 方法。每当我尝试发送请求时，都会收到一条错误消息，指出不允许使用此方法。是否有关于我可以编辑的当前代码的建议以使此请求正常工作？

我想更接近这种格式
@Test
@RestAssuredMethod(config = "src/test/resources/config/sampleRest.json")
public void getResponse() throws IOException {
Response response3 = given().log().all()
.when().get("updateFiles/")
.then().assertthat()
.statusCode(HttpStatus.SC_OK) //SC_OK = 200
.body("status[0].model",equalTo("Success"))
.header("Content-Type",containsstring("application/json"))
.log().all(true)
.extract().response();
String firstResponse = response3.jsonPath().get("status[0].model");
asserts.assertEquals(firstResponse,"SUCCESS","Response does not equal SUCCESS");
List allResponses = response3.jsonPath().getList("status[0].model");
System.out.println("**********" + favoriteModels);
asserts.assertTrue(allResponses.contains("Success"),"There are no success responses");
}
编辑：这是我尝试使用完整 REST 方法集成的工作发送/接收响应：
package com.chillyfacts.com;
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class Send_XML_Post_Request {
public static void main(String[] args) {
try {
String url = "<enterEndpointHere>";
URL obj = new URL(url);
HttpURLConnection httpconnection = (HttpURLConnection) obj.openConnection();
httpconnection.setRequestMethod("POST");
httpconnection.setRequestProperty("Content-Type","text/xml; charset=utf-8");
httpconnection.setDoOutput(true);
String xml = "<pasteXMLRequestHere>"
DataOutputStream writeRequest = new DataOutputStream(httpconnection.getoutputStream());
writeRequest.writeBytes(xml);
writeRequest.flush();
writeRequest.close();
String responseStatus = httpconnection.getResponseMessage();
System.out.println(responseStatus);
BufferedReader in = new BufferedReader(new InputStreamReader(
httpconnection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println("\n **** RESPONSE FROM ENDPOINT RECEIVED ****: \n\n" + response.toString() + "\n\n *************** END OF RESPONSE *************** \n");
} catch (Exception e) {
System.out.println(e);
}
}
}
