我在使用apache httpclient时遇到了一个非常奇怪的问题，我在尝试向本地服务器执行发布请求时遇到“目标主机未指定”错误，它在Windows 10中工作但在Ubuntu中不起作用。
这是代码
public JSONObject sendServerRequest(JSONObject message, String url, String secret) throws Exception {
SimpleDateFormat sdf = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss");
String timestamp = sdf.format(Calendar.getInstance().getTimeInMillis());
message.put(Web.auth.timeStamp, timestamp);
HttpClient httpClient = HttpClientBuilder.create().build();
HttpPost req = new HttpPost(url);
StringEntity resp = new StringEntity(message.toString());
req.addHeader("content-type", "application/json");
req.addHeader("Authorization", hmac(secret, message.toString()));
req.setEntity(resp);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = httpClient.execute(req, responseHandler);
return new JSONObject(response);
}
我将以下网址传递给此功能
public static class urls {
// private static final String serverAddress = "http://192.168.100.5:8000";
private static final String serverAddress = "http://192.168.0.19:8000";
public static final String shopRegistration = serverAddress + "/shop/signup";
