Chapter 4.40. 文件服务

外部系统通过调用上传接口，可以把外部系统需要上传到的附件先通过此接口完成，如外边系统发起表单流程，需要先调用此接口。

名称

uploadService 文件上传服务。

请求路径：/seeyon/uploadService.do?method= processUploadService

参数：

返回值：string

成功则返回生成的附件id，如果多个文件上传则以"|"符号分割返回

示例：

      URL preUrl = null;
       URLConnection uc = null;
       preUrl = new URL("http://128.2.3.174/seeyon/uploadService.do?
       method = processUploadService"
           +"&senderLoginName="+"zy"
           +"&token="+"997a7cdc-2399-47e8-991e-96c859cccc7f");
       String s = parameters.toString();
       uc = preUrl.openConnection();
       HttpURLConnection hc = (HttpURLConnection) uc;
       hc.setDoOutput(true);
       hc.setUseCaches(false);
       hc.setRequestProperty("contentType", "charset=utf-8");
       hc.setRequestMethod("POST");
       BufferedInputStream  input=new BufferedInputStream(new FileInputStream("c:/LDAP集成设计文档.doc"));
       String BOUNDARY = "---------------------------7d4a6d158c9"; // 分隔符
       String fileName="LDAP集成设计文档.doc";
       StringBuffer sb = new StringBuffer();
       sb.append("--");
       sb.append(BOUNDARY);
       sb.append("\r\n");
       sb.append("Content-Disposition: form-data; \r\n name=\"1\"; filename=\""+fileName+"\"\r\n");
       sb.append("Content-Type: application/msword\r\n\r\n");
 
       hc.setRequestProperty("Content-Type",
           "multipart/form-data;boundary=" + "---------------------------7d4a6d158c9");
       byte[] end_data = ("\r\n--" + BOUNDARY + "--\r\n").getBytes();
       DataOutputStream dos = new DataOutputStream(hc.getOutputStream());
       dos.write(sb.toString().getBytes("utf-8"));
       int cc=0;
       while((cc=input.read())!=-1)
       {
           dos.write(cc);
       }
       dos.write(end_data);
       dos.flush();
       dos.close();
       FileOutputStream file = new FileOutputStream("c:/test.txt");
       InputStream is = hc.getInputStream();
       int ch;
       while ((ch = is.read()) != -1) {
            file.write(ch);
       }
       if (is != null)
       is.close();
 

上传下载本地调用：

     import com.seeyon.oainterface.impl.exportdata.FileDownloadExporter
      FileDownloadExporter exporter=new FileDownloadExporter();
      exporter.processDownload(token, fileId, out);
 
      import com.seeyon.oainterface.impl.exportdata.FileUploadExporter;
      FileUploadExporter  fileUpload=new FileUploadExporter();
      String outStr= fileUpload.processUpload(request);
