This POST form of Multi download, download the result of the same file name, constantly covered, how to solve?

[#1]

Multi downloads with JMP 17 get downloaded files, but all files with the same name, and only one last downloaded file.

Thanks!

urls = {};
u = "https://apphq.ip.com/w1/api/index.php";
h = ["Content-Type" => "application/x-www-form-urlencoded; charset=UTF-8"];
d0 = Current Data Table();
For( j = 1, j <= 3, j++,
	gp = d0[j, "IP"];
	Insert Into(
		urls,
		"a=GetMainMonitor_Trend_w30&Money=0&apiv=w36&c=StockL2Data&StockID=" || gp ||
		"&PhoneOSNew=1&"
	);
);

requests = New Multi HTTP Request();
s0 = N Items( urls );
For( i = 1, i <= s0, i++,
	Try( rs = New HTTP Request( URL( u ), Method( "POST" ), JSON( urls[i] ), Headers( h ) ) );
	requests << Add( rs );
);
da = requests << Download( "show progress", "detailed" );

What can I do if the temporary file name is the same during concurrent downloads using JMP 17?

OK、Thanks!

I forgot all about it.

requests<<Add(rs,"test"||char(i));
