REST 保证 - org.apache.http.NoHttpResponseException: <server_address>:80 未能响应
REST Assured - org.apache.http.NoHttpResponseException: <server_address>:80 failed to respond
我间歇性地遇到 REST Assured 3.0.3 的这个问题，相应的代码行在 for 循环中。
这是一个简单的 GET 调用，如下所述：
response = given().setBaseUri(someBaseUri).setBasePath(someEndPoint).param("key", "value").header("X-Authorization-Token", my_auth_token).get();
我发现了几个建议使用 ConnectionConfig 解决问题的 Whosebug 答案，但我不知道如何在使用 REST Assured 时解决问题。
下面是完整的轨迹：

请帮忙
添加这段代码似乎解决了这个问题。即使使用速度较慢的暂存测试服务器，我也没有遇到过这个问题。
Response response = given()...get();
ConnectionConfig connectionConfig = new ConnectionConfig();
connectionConfig.closeIdleConnectionsAfterEachResponse();
不过我不明白的是，ConnectionConfig 对象如何与 Response 对象一起工作。
如果您了解 RestAssured http 连接建立机制，RestAssuredConfig 的每个新对象都会创建与服务器的新 httpclient 连接。对于少数 API 调用，可能会以块的形式接收到响应，在这种情况下，服务器可能会间歇性地关闭连接，并且由于此连接处于陈旧状态和 NoHttpResponse，客户端不知道它错误被抛出。
要处理此间歇性问题，最好的方法是使用一些重试机制来创建新的 http 连接并关闭之前发生 NoHttpResponseException 的连接。
更好的代码示例：
given().config(RestAssuredConfig.config().connectionConfig(
ConnectionConfig.connectionConfig().closeIdleConnectionsAfterEachResponse()
)
Apache Http Client 5.0 中存在相同问题
org.apache.hc.core5.http.NoHttpResponseException: localhost:8443 failed to respond
