Chapter 4.37. 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);
