将本地文件从电子推送到服务器PHP

Question

js and electron. I have a problem to push my local images file to my remote server. The server is using php. Here's my client side code :

 var documentList = []; var stmtDoc = db.prepare("SELECT * FROM `tb_dokumen_pasien`"); while(stmtDoc.step()) { var rowDoc = stmtDoc.getAsObject(); var data = fs.createReadStream(__dirname + "/resources/" + rowDoc['id'] + "/" + rowDoc['doc_name']); var document = { "document_name" : rowDoc['doc_name'], "data" : data } documentList.push(document); } 

And after that I create an ajax post request to my remote server :

 $.ajax({ url: "http://url/web_api.php?action=test_upload", type: 'POST', data : { "document_list": documentList }, dataType: "json", success: function(response) { console.log(response); } }); 

When I test it, in my developer tools console I've got this message :

internal/streams/BufferList.js:15 Uncaught TypeError: Cannot read property 'length' of undefined

And the file is not sent to the server. Can anyone help me how can I solve this? Thanks

Answer 1

for a while I found the working solution for this problem is use base64 format to send it to the remote server :

 var documentList = []; var stmtDoc = db.prepare("SELECT * FROM `tb_dokumen_pasien`"); while(stmtDoc.step()) { var rowDoc = stmtDoc.getAsObject(); var data = fs.createReadStream(__dirname + "/resources/" + rowDoc['id'] + "/" + rowDoc['doc_name']); var base64 = Buffer.from(data).toString('base64'); var document = { "document_name" : rowDoc['doc_name'], "data" : base64 } documentList.push(document); } 

And I still finding the best approach instead of using base64, Thanks
