内容图文
HttpClient oHttpClient = new HttpClient(); // make post-method PostMethod post = new PostMethod(_sPostUri); post.setRequestHeader("FileExt",sFileExt); //post.setRequestHeader("Content-Type","multipart/form-data"); if (_btContent != null) { ByteArrayRequestEntity entity = new ByteArrayRequestEntity(_btContents); post.setContentChunked(true); post.setRequestEntity(entity); } int httpResult = 0; try { httpResult = oHttpClient.executeMethod(post); //获取返回值 文件名称 sfilename = post.getResponseBodyAsString(); } catch (Exception ex) { post.releaseConnection(); System.out.println("提交数据时失败"); } finally { post.releaseConnection(); } temp_WebClient = new WebClient();temp_WebClient.Headers.Add("FileExt", "jpg");fileBytes = File.ReadAllBytes("c:\\1.jpg");responseArray = temp_WebClient.UploadData("http://localhost/fileuploader.do", "POST", fileBytes);resStr = Encoding.UTF8.GetString(responseArray); 两段程序都是向一个网址post一个文件，改怎么用php实现，求代码，谢谢！
回复讨论(解决方案)
如果要实现向一个网址post一个文件，php中可以用curl提交。你可以搜索一下用法。
试过了，报了一堆错，我对java是一窍不通，我测试提交到我的php服务器端一点问题都没有，可正式提交到另外一台java服务器的do文件后，就报错，几天了，郁闷死，求助。
