编辑：好的，我发现这绝对是一个身份验证问题：这个简短的Python脚本做得很好：
import requests
from requests.auth import HTTPBasicAuth
URL = "https://wiki.myCompany.corp/confluence-dev/rest/api/content/180158489";
r = requests.get(URL, auth = HTTPBasicAuth('myUser', 'myPass'), verify=False)
r.raise_for_status()
print(r.json())
为什么它对Java不起作用？？
初步问题：
我试图使用Apache httpclient/httpcore编写一个简单的Http请求来获取Confluence页面的内容，但我得到的只是状态404。
这是我的代码：
String url = "https://wiki.mycompany.corp/confluence-dev/rest/api/content/180158489";
HttpHost proxy = new HttpHost("proxy.myCompany.at", 57165);
DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("myUsername", "myPassword");
provider.setCredentials(AuthScope.ANY, credentials);
HttpClientBuilder builder = HttpClientBuilder.create();
builder.setDefaultCredentialsProvider(provider);
builder.setRoutePlanner(routePlanner);
HttpClient client = builder.build();
HttpGet get = new HttpGet(url);
HttpResponse r = client.execute(get);
System.out.println(r.getStatusLine().toString());
输出：HTTP/1.1 404未找到
当我在浏览器中打开URL时，只要我登录，我就会得到正确的合流JSON。当我注销并尝试在浏览器中打开该URL时，我会得到一个JSON
{
"statusCode":404,
"data":
{
"authorized":false,
"valid":true,
"allowedInReadOnlyMode":true,
"errors":[],"successful":false
},
"message":"No content found with id: ContentId{id=180158489}",
"reason":"Not Found"
}
所以对我来说，这看起来像是不知何故，我的代码中的身份验证无法正确工作。
你知道这里会出什么问题吗？
好的，我找到了解决方案（不知何故）。在我的Java代码中，身份验证不起作用（无论出于什么原因，我在多个示例中看到过这样做…）。
不管怎样，如果我手动设置标题，就像这样：
HttpGet request = new HttpGet(url);
String authorizationString = "Basic " + Base64.getEncoder().encodeToString(("myUser:myPass").getBytes()).replace("\n", "");
request.setHeader(HttpHeaders.AUTHORIZATION, authorizationString);
HttpClient client = HttpClientBuilder.create().build();
HttpResponse response = client.execute(request);
System.out.println(response.getStatusLine().toString());
结果：
HTTP/1.1 200 OK
