【中文标题】在 solr 上收到错误请求 (400)

【英文标题】：Getting bad request (400) on solr

【发布时间】：2015-10-20 03:36:32

【问题描述】：

solr 遇到了一个奇怪的问题。 使用HttpWebRequest(C#) 请求网址时出现bad request(400) 错误

我们正在使用以下代码 HttpWebRequest 请求 = (HttpWebRequest)HttpWebRequest.Create(solrFinalUrl); HttpWebResponse 响应 = ttpWebResponse)request.GetResponse(); 流接收流 = response.GetResponseStream(); StreamReader readStream = new StreamReader(receiveStream,Encoding.UTF8); String jsonString = readStream.ReadToEnd();

但是当我在浏览器上点击 url 时，它会给出预期的结果。
