一. 下載 phantomjs
具體下載方式 再也不詳細說明了.
二. 建立一個 rasterize.js 文件 (放在哪裏都行, 我這裏是放在了項目中) . 代碼內容以下
var page = require('webpage').create(),
system = require('system'),
address, output, size;
if (system.args.length < 3 || system.args.length > 5) {
console.log('Usage: rasterize.js URL filename [paperwidth*paperheight|paperformat] [zoom]');
console.log(' paper (pdf output) examples: "5in*7.5in", "10cm*20cm", "A4", "Letter"');
phantom.exit(1);
} else {
address = system.args[1];
output = system.args[2];
page.viewportSize = { width: 600, height: 600 };
if (system.args.length > 3 && system.args[2].substr(-4) === ".pdf") {
size = system.args[3].split('*');
page.paperSize = size.length === 2 ? { width: size[0], height: size[1], margin: '0px' }
: { format: system.args[3], orientation: 'portrait', margin: '1cm' };
}
if (system.args.length > 4) {
page.zoomFactor = system.args[4];
}
page.open(address, function (status) {
if (status !== 'success') {
console.log('Unable to load the address!');
phantom.exit();
} else {
window.setTimeout(function () {
page.render(output);
console.log("ok");
phantom.exit();
}, 200);
}
});
}
三 . C# 調用 phantomjs
private static string[] GeneratePdf(string relativeUrl, string pdfName, int isA4 = 0)
{
try
{
string url = relativeUrl;
string fileNameWithOutExtention = pdfName + DateTime.Now.ToString("_yyyyMMdd_HHmmssffff");
string pdfSavePath = Path.Combine("本身寫路徑", string.Format("{0}.pdf", fileNameWithOutExtention));
string filePath = Path.Combine("本身寫路徑", "phantomjs.exe");
string jsPath = Path.Combine("本身寫路徑", "rasterize.js");
string argument = string.Empty;
if (isA4 != 0)
{
argument = string.Format(" --ignore-ssl-errors=yes {0} \"{1}\" {2} \"{3}\" ", jsPath, url, pdfSavePath, "A4");
}
else
{
argument = string.Format(" --ignore-ssl-errors=yes {0} \"{1}\" {2} ", jsPath, url, pdfSavePath);
}
using (System.Diagnostics.Process exep = new System.Diagnostics.Process())
{
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.FileName = filePath;
startInfo.Arguments = argument;
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
startInfo.RedirectStandardInput = true;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
exep.StartInfo = startInfo;
exep.Start();
exep.WaitForExit();
char[] res = new char[2];
exep.StandardOutput.Read(res, 0, res.Length);
string sRes = new string(res);
if (sRes == "ok")
{
}
}
return new string[] { pdfSavePath };
}
catch (Exception e)
{
}
return new string[] { null, null };
}
