Question

我尝试发布base64代码保存为图片，但在尝试提交base64代码时，我无法发布文本框的值。

是否有限制通过发布表单发送给代码？

由于无法获得以下文本框的值，我收到错误：

ADODB.Stream错误＆＃39; 800a0bb9＆＃39;

参数类型错误，超出可接受的范围，或彼此冲突。

我的HTML代码

<form method="POST" action="?X=1" id="myForm">
    <input type="text" name="img_val" id="img_val" value="" />
    <input type="submit" value="Submit Largest Code" />
</form>

我的ASP代码：

<%

IF LEN(Request("X"))>0 THEN

base64String = Trim(Request.Form("img_val"))
Set tmpDoc = Server.CreateObject("MSXML2.DomDocument")
Set nodeB64 = tmpDoc.CreateElement("b64")
nodeB64.DataType = "bin.base64"
nodeB64.Text = Mid(base64String, InStr(base64String, ",") + 1)
set bStream = server.CreateObject("ADODB.stream")
bStream.type = 1
call bStream.Open()
call bStream.Write(nodeB64.NodeTypedValue)
caminho=Server.MapPath("/SS/imagem.png")
call bStream.SaveToFile(caminho, 2)
call bStream.close()
set bStream = nothing

END IF
%>
