java - 如何使用 apache httpclient 创建 get 请求，url 中带有 "bad"符号(需要编码)？

Question

我正在尝试创建自动测试(java)。服务应该能够正确处理请求:返回 json 而不是 java 堆栈跟踪。

在这个测试中，我有类似 #host/some/path/?param=% 的情况

好的，% 是不正确的符号，应该进行编码。当您是开发人员并创建发送请求的服务时。但这是一个测试。

所以问题是:如何在不编码的情况下使用 url“按原样”创建获取响应？目前我正在使用 apache httpclient (4.5.2)

目前我没有什么特别的:

public void fetchGet(String uri) {
    HttpGet getRequest = new HttpGet(uri);

    HttpClient client = HttpClientBuilder.create().build();

    try {
        response = client.execute(requestBase);
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        requestBase.abort();
    }
}

使用BasicHttpRequest而不是HttpGet来撰写请求消息

CloseableHttpClient client = HttpClientBuilder.create().build();
BasicHttpRequest request = new BasicHttpRequest("GET", "all kind of c%.p");

try (CloseableHttpResponse response1 = client.execute(new HttpHost("www.google.com"), request)) {
    System.out.println(response1.getStatusLine());
    EntityUtils.consume(response1.getEntity());
}

此代码产生以下消息交换
