Unable to store server side response file
Aug 3 2018 9:00 AM
Hi,
I need to generate and download pdf file on server in node js. I have created api for that. When i directly call api in browser, it works fine and download file but when I call file from axios post, it of my client side code, it is not downloding file. Following is my code. Please suggest.
app.get(
"/getpdf/*"
,
function
(req, res) {
var
query =
"SELECT UserId,UserName,Password,UserType,Mobile,Status,Password1,Password2,Password3,replace(CONVERT(VARCHAR(10), DateCreated, 103),'01/01/1900','-') FROM AppUsers"
;
var
fields =
"User Id,Username,Password,Usertype,Mobile,Status,Password1,Password2,Password2,Created Date"
;
//GetPDF(res, query, fields);
GetCSV(res, query);
});
function
GetPDF(res, qry, fields) {
var
request =
new
sql.Request();
// query to the database and get the records
request.query(qry,
function
(err, result) {
if
(err) {
console.log(err);
res.send(err);
}
else
{
let rdata = result.recordsets[0];
var
ShowLabel =
true
;
var
JSONData = result.recordsets[0];
var
arrData =
typeof
JSONData !=
'object'
? JSON.parse(JSONData) : JSONData;
var
number_of_rows = rdata.length;
var
table_body =
'<html><head>'
;
table_body +=
'<style>table {border-collapse: collapse;border-radius:6px;width:90%;font-family:Trebuchet MS;} .rd{font-weight:bold;} .rd {font-weight: bold; font-size:18px;background:#2980B9;color:#fff}'
;
table_body +=
' .r1 {background-color:#F6F6F6;color:#666666;}'
;
table_body +=
' .r2 {background-color:#E9E9E9;color:#666666;}'
;
table_body +=
'td {border: 1px solid grey;text-align: left;padding: 4px;}'
;
table_body +=
'table.print-friendly tr td, table.print-friendly tr th {page-break-inside: avoid;}'
;
table_body +=
'</style></head><body>'
;
table_body +=
'<center><h1>Appuser List</h1>'
;
table_body +=
'<div class="table-responsive">'
;
table_body +=
'<table class="table">'
;
var
str_Fields = fields.split(
','
);
table_body +=
'<tr class="rd">'
;
for
(i = 0; i < str_Fields.length; i++) {
if
(i % 6 == 0)
{
table_body +=
'</tr><tr class="rd">'
;
}
table_body +=
'<td>'
+ str_Fields[i] +
'</td>'
;
}
table_body +=
'</tr>'
;
for
(
var
i = 0; i < arrData.length; i++) {
var
cssclass =
''
;
if
(i % 2 == 0) {
cssclass =
'r1'
;
}
else
{
cssclass =
'r2'
;
}
table_body +=
'<tr class="'
+ cssclass +
'">'
;
var
k = 0;
for
(
var
index
in
arrData[i]) {
if
(k % 6 == 0) {
table_body +=
'</tr><tr class="'
+ cssclass +
'">'
;
}
table_body +=
'<td>'
;
table_body += arrData[i][index];
table_body +=
'</td>'
;
k++;
}
table_body +=
'</tr>'
;
}
table_body +=
'</table></div></center></body></html>'
;
var
d =
new
Date();
var
fname = d.getDate() +
""
+ d.getMonth() +
""
+ d.getYear() +
""
+ d.getHours() +
""
+ d.getMinutes() +
""
+ d.getSeconds();
res.header(
'Content-Disposition'
,
'attachment; filename='
+ fname +
'.pdf'
);
pdf.create(table_body, options).toStream(
function
(err, stream) {
stream.pipe(res);
});
}
});
}
Client side code:
ExportPdf()
{
axios.get(
'http://127.0.0.1:9000/getpdf/*'
, {data:
this
.data}).then(res => {
});
},
