HCL Domino AppDevPack - writeAttachments

Question

新的V1.0.2具有将附件上载到domino文档的新功能。我的上传代码是成功的，只要我使用的文件<= 48KB。只要我试图上传一个更大的文件，上传就会发生，在domino文档中我找到了一个大小合适的附件-但是文件已经损坏了！

以下是我的代码(对应于appdev pack文档中较大文件的示例代码)：

for (var x = 0; x < files["tskFile"].length; x++) {          
          let sFilename = files["tskFile"][x].originalname;         
          let sPath = files["tskFile"][x].path;
          let buffer = fs.readFileSync(sPath);
          const writable = await db.bulkCreateAttachmentStream({});
          writable.on('error', e => {
            // An error occurred and the stream is closed
            console.error("Error on write ", e)
          });
          writable.on('response', response => {
            // The attachment content was written to the document and a
            // response has arrived from the server
            console.log(">> File " + sFilename + " saved to doc ")
          });
          let error;         
          // Write the image in n chunks
          let offset = 0;
          const writeRemaining = () => {
            if (error) {
              return;
            }
            let draining = true;
            while (offset < buffer.length && draining) {
              const remainingBytes = buffer.length - offset;
              let chunkSize = 16 * 1024;
              if (remainingBytes < chunkSize) {
                chunkSize = remainingBytes;
              }                            
              const chunk = new Uint8Array(
                buffer.slice(offset, offset + chunkSize),
              );
              draining = writable.write(chunk);              
              offset += chunkSize;
            }

            if (offset < buffer.length) {
              // Buffer is not draining. Write some more once it drains.              
              writable.once('drain', writeRemaining);
            } else {
              writable.end();                           
            }
          };          
          writable.file({
            unid: unid,
            fileName: sFilename,
          });
          writeRemaining();
        } // end forall attachments

下面是我的服务器的notes.ini变量：

PROTON_MAX_WRITE_ATTACHMENT_MB=30, 
PROTON_MAX_ATTACHMENT_CHUNK_KB=50, 
PROTON_MIN_ATTACHMENT_CHUNK_KB=8

是我的错误还是AppDevPack中的bug？有没有人尝试过这个新功能？

Answer 1

我可以在64位Windows上用Proton重现类似的问题。在Linux上运行Proton时，我无法重现。我使用的客户端代码与您的不同，但我99%确定这是Proton中仅限Windows的错误。当我们有更多信息时，我们将更新此答案。同时，你能在Linux上试用Proton吗？

我们已经找到了一个修复，它将包含在我们的下一个drop中。感谢您的这份报告！
