我正在尝试从我的 Java 客户端代码对 URL 进行 HTTP POST。它是一个标准的普通独立 java 类但我反复收到以下错误。我在网上搜索但找不到任何合适的解决方案。我已经提供了以下所有信息。

下面是我得到的错误。

PostMethod filePost = new PostMethod(targetURL); 

filePost.getParams().setBooleanParameter(HttpMethodParams.USE_EXPECT_CONTINUE, false);

Part[] parts = {new FilePart(targetFile.getName(), targetFile)};

filePost.setRequestEntity(new MultipartRequestEntity(parts, filePost.getParams()));

HttpClient client = new HttpClient(); 

client.getHttpConnectionManager().getParams().setConnectionTimeout(8000); 

int status = client.executeMethod(filePost)

java.net.SocketException：连接重置

您能否请教代码有什么问题以及为什么我每次都遇到此连接超时。它非常严重地影响了我的工作，所以你们能帮我找到解决这个问题的方法吗？

当您没有正确配置服务器（协议/IP/端口）时，通常会出现超时。你能从浏览器发出请求吗？有防火墙问题吗？
