兄弟，解决了47001问题了吗？

因为我发起post连接的服务器的域名，跟保存图片的域名不是同一个，这样可以吗？

final String newLine = "\r\n"; final String boundaryPrefix = "--"; // 定义数据分隔线 String BOUNDARY = "============" + "1234567890" + "============"; // 服务器的域名 URL url = new URL(urls); // 建立http连接 System.out.println("url:"+url); // 创建url资源 HttpURLConnection conn = (HttpURLConnection) url.openConnection(); // 设置允许输出 conn.setRequestMethod("POST"); // 设置维持长连接 conn.setDoOutput(true); // 设置允许输入 conn.setDoInput(true); // 设置不用缓存 conn.setUseCaches(false); // 设置传递方式 conn.setRequestProperty("Connection", "Keep-Alive"); // 设置文件字符集: conn.setRequestProperty("Charset", "UTF-8"); // 转换为字节数组 conn.setRequestProperty("Content-Type","multipart/form-data; boundary=" + BOUNDARY); //获取图片URL imgUrl = new String(readFromUrl(storageUrl),"UTF-8"); byte[] imgByte = readFromUrl(imgUrl); System.out.println("imgUrl:" + imgUrl); // 上传文件 StringBuilder sb = new StringBuilder(); StringBuffer sb1=new StringBuffer(); sb.append(boundaryPrefix); sb.append(BOUNDARY); sb.append(newLine); // 文件参数 sb.append("Content-Disposition: form-data;name=\"image\";filename=\"" + imgUrl +"\""); sb.append(newLine); sb.append("Content-Type:"+URLConnection.guessContentTypeFromName(imgUrl)); // 参数头设置完以后需要两个换行，然后才是参数内容 sb.append(newLine); sb.append(newLine); System.out.println("-----111111-----"); conn.connect(); OutputStream out = new DataOutputStream(conn.getOutputStream()); byte[] head = sb.toString().getBytes("utf-8"); out.write(head); System.out.println("sb:\n\r"); System.out.println(sb.toString()); InputStream in = new URL(imgUrl).openStream(); byte[] bufferOut = new byte[1024]; int bytesRead = -1; while ((bytesRead = in.read(bufferOut)) != -1) { out.write(bufferOut, 0, bytesRead); } in.close(); System.out.println(imgUrl); byte[] foot = ("\r\n" + boundaryPrefix + BOUNDARY + boundaryPrefix + "\r\n").getBytes("utf-8"); System.out.println("\r\n" + boundaryPrefix + BOUNDARY + boundaryPrefix + "\r\n"); out.write(foot); out.flush(); out.close(); LOG是： tomcat default url:https://api.weixin.qq.com/wxa/msg_sec_check?access_token=31_XXXXXXXXNIQ tomcat default imgUrl:https://XXX/9D9000001B78E1F0014601F49.jpg tomcat default -----111111----- tomcat default sb: tomcat default tomcat default --============1234567890============ tomcat default Content-Disposition: form-data;name="image";filename="https://XXX/9D9000001B78E1F0014601F49.jpg" tomcat default Content-Type:image/jpeg tomcat default tomcat default https://XXX/9D9000001B78E1F0014601F49.jpg tomcat default tomcat default --============1234567890============--
