转换标志TRUE插入操作失败 [英] Insert operation with convert flag TRUE fails

问题描述

我使用xdocreport生成WORD文件的报告。

在生成的报告中，我使用MIME-TYPE application / application创建了 InputStreamContent vnd.openxmlformats-officedocument.wordprocessingml.document（MS WORD - DOCX）写入Google Drive：

  //使用xdocreport创建Word文件流
 OutputStream2InputStream outputStream = new OutputStream2InputStream（）; // buffer 
 report.process（context，outputStream）; 
 //为Google Drive创建输入流
 InputStreamContent inputStream = new InputStreamContent（application / vnd.openxmlformats-officedocument.wordprocessingml.document，
 outputStream.getInputStream（））; 
 inputStream.setLength（outputStream.size（））; 
  

写入MSWORD DOCUMENT WORKS FINE（CONVERT = FALSE）：

  File file = new File（）; 
插入insertOperation = service.files（）。insert（file，inputStream）.setConvert（false）; 
 file.setTitle（test.docx）; 
 file.setMimeType（inputstream.getType（））; 
文件结果= insertOperation.execute（）; 
  

导致在我的Google云端硬盘中创建WORD DOCX文件。

使用CONVERT = TRUE FAILS写入输入流

  File file = new File （）; 
插入insertOperation = service.files（）。insert（file，inputStream）.setConvert（true）; 
 file.setTitle（test）; 
 //file.setMimeType（inputstream.getType（））; //这里有什么？ 
文件结果= insertOperation.execute（）; 
  

结果

1。当不设置MIME类型时：新创建的文件 result 具有 0字节和 MIME类型：application / vnd。 google-apps.kix

2。当设置MIME类型： MIME-TYPE设置为application / vnd.google-apps.document并且convert = true时，结果为400：BAD REQUEST。

我做错了什么？

解决方案

这是一个常见问题。请勿在请求元数据中设置MIME类型。 Google云端硬盘将决定要转换为的MIME类型。

您的行标记为 //此处？应该保留出去。

I am generating reports resulting in WORD files using xdocreport.

From the generated report, I create a InputStreamContent with MIME-TYPE "application/vnd.openxmlformats-officedocument.wordprocessingml.document" (MS WORD - DOCX) to write to Google Drive :

// create Word file stream using xdocreport
OutputStream2InputStream outputStream = new OutputStream2InputStream(); // buffer
report.process(context, outputStream);
// create inputstream for Google Drive
InputStreamContent inputStream = new InputStreamContent("application/vnd.openxmlformats-officedocument.wordprocessingml.document",
        outputStream.getInputStream());
inputStream.setLength(outputStream.size());

WRITING MSWORD DOCUMENT WORKS FINE (CONVERT= FALSE) :

File file = new File();
Insert insertOperation = service.files().insert(file, inputStream).setConvert(false);
file.setTitle("test.docx");
file.setMimeType(inputstream.getType());
File result = insertOperation.execute();

Resulting in a WORD DOCX file created on my Google Drive.

WRITING SAME INPUTSTREAM WITH CONVERT=TRUE FAILS

File file = new File();
Insert insertOperation = service.files().insert(file, inputStream).setConvert(true);
file.setTitle("test");
//file.setMimeType(inputstream.getType()); // what here ? 
File result = insertOperation.execute();

RESULT

1. When NOT setting the mime type : newly created File result has 0 bytes and MIME-type: application/vnd.google-apps.kix

2. When setting the mime type : MIME-TYPE set to "application/vnd.google-apps.document" and convert = true, results in 400: BAD REQUEST.

What am I doing wrong ?

解决方案

This is a common problem. Don't set a MIME type in the request metadata. Google Drive will decide the MIME type to convert to.

Your line marked // what here ? should be left out.
