java - 有没有办法防止 Apache CloseableHttpClient 抛出 HttpResponseException？

Question

我正在使用 Apache HttpComponents (4.5.11) 来测试 Web API。

对于负面测试(例如发送错误的请求)，我还想检查响应正文，但 CloseableHttpClient 抛出 HttpResponseException 以及响应的状态代码，而不是返回实际的回复。有没有办法防止这种情况，或者我应该切换到另一个库(例如 RestAssured)？

这是我的做法:

try (CloseableHttpClient httpClient = HttpClients.createDefault();
        CloseableHttpResponse response = httpClient.execute(request)) {
     ResponseHandler<String> handler = new BasicResponseHandler();
     String body = handler.handleResponse(response);
     //Deserialize and perform response assertions..
} catch(HttpResponseException e){
    //Exception is caught here..
}

pom.xml 依赖项:

    <dependency>
      <groupId>org.apache.httpcomponents</groupId>
      <artifactId>httpclient</artifactId>
      <version>4.5.11</version>
    </dependency>

我不确定是否理解这个问题。没有什么可以阻止您直接从响应对象获取状态代码并读取响应内容。

try (CloseableHttpClient httpClient = HttpClients.createDefault();
     CloseableHttpResponse response = httpClient.execute(request)) {
    int statusCode = response.getStatusLine().getStatusCode();
    final HttpEntity entity = response.getEntity();
    if (entity != null) {
        try (InputStream inputStream = entity.getContent()) {
            // Do something useful with the response
        }
    }
}
