HTML转PDF目前最优解决方案：headless chrome

网上关于headless chrome大多是科普，只是单纯介绍其功能，一些细节仍然需要补充

前置条件：

• chrome
  
  虽然网上都是使用的Google Chrome Canary ，但我没进行测试
  

	const char a[] = "/c \"C:/Program Files (x86)/Google/Chrome/Application/chrome.exe\" --headless --disable-gpu --print-to-pdf-no-header --print-to-pdf=D:/212.pdf file:///D:/1.html";
	//本人的功能诉求比较简单，就是单纯需要不带页眉页脚的pdf而已
	int rt = ShellExecuteA(NULL, "open", "cmd.exe",a, NULL, SW_HIDE);

参数介绍：

• /c
  这是cmd 的参数，执行完关闭窗口

• “C:/Program Files (x86)/Google/Chrome/Application/chrome.exe”
  chrome路径
  设置环境变量就可以摆脱前面冗余的目录

• –headless --disable-gpu
  开启无GUI的chrome

• –print-to-pdf-no-header
  不显示页眉页脚（如果需要页眉页脚直接删除此参数）

• –print-to-pdf=D:/212.pdf
  转化出来的pdf存放位置

• file:///D:/1.html
  待转化的html文件路径

其中–print-to-pdf-no-header和–print-to-pdf=D:/212.pdf都是必须的，即：不可以写成–print-to-pdf-no-header=D:/212.pdf

扩展参数介绍

// The background color to be used if the page doesn't specify one. Provided as
// RGBA integer value in hex, e.g. 'ff0000ff' for red or '00000000' for

// TODO(crbug.com/571003): Once PasswordStore no longer uses the Keyring or

// Use the given address instead of the default loopback for accepting remote

此为headless chrome的命令（绝对原汁原味），包括非常多的功能，需要者自取
headless chrome（需要*，没*看上面代码即可）

以上就是全部内容，希望大家不要和我走一样的弯路，节约时间
能用Google就不要bing，能用bing就别用百度，搜索引擎是发散思维，百度用着用着就成信息茧房了。
