java - HttpGet get = new HttpGet(url);给予异常(exception)

Question

我正在尝试做一件非常简单的事情，几天前它还在工作。

CloseableHttpClient client = HttpClientBuilder.create().build();
            HttpGet get = new HttpGet(url);
            HttpResponse response = client.execute(get);

出现以下错误

Caused by:
            java.lang.IllegalStateException: Unsupported cookie spec: default
                at org.apache.http.cookie.CookieSpecRegistry.getCookieSpec(CookieSpecRegistry.java:110)

我之前使用过时的客户端遇到过这个错误，我将其更改为使用 HTTPClientBuilder。我不确定它为什么在 HTTPGet 上给出。非常感谢任何帮助。

Answer 1

这是 apache httpclient 的一个错误，版本 4.4 beta 1 有这个错误，但版本 4.3.6 对我来说工作正常。

如果您使用的是 maven，请在 pom 中使用以下内容:

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.3.6</version>
    </dependency>

并且在他们修复此错误之前不要将其更新到 4.4。
