考慮以下代碼，其中BaseAddress定義了部分URI路徑。using (var handler = new HttpClientHandler())using (var client = new HttpClient(handler)){    client.BaseAddress = new Uri("http://something.com/api");    var response = await client.GetAsync("/resource/7");}我希望這能向發(fā)出GET請求http://something.com/api/resource/7。但事實(shí)并非如此。經(jīng)過一些搜索，我找到了這個(gè)問題和答案：HttpClient與BaseAddress。建議將其放置/在末尾BaseAddress。using (var handler = new HttpClientHandler())using (var client = new HttpClient(handler)){    client.BaseAddress = new Uri("http://something.com/api/");    var response = await client.GetAsync("/resource/7");}它仍然不起作用。這里是文檔：HttpClient.BaseAddress這是怎么回事？
