将原始数据发布到流
问题
您希望将原始文本数据发布到流中。
解决方案
使用 HTTP In 节点监听 Content-Type 设置为 text/plain 的 POST 请求，并将发布的数据作为 msg.payload 访问。
示例
[{"id":"3e1c5107.c1e3ae","type":"http in","z":"3045204d.cfbae","name":"","url":"/hello-raw","method":"post","swaggerDoc":"","x":120,"y":920,"wires":[["cf679478.309868"]]},{"id":"cf679478.309868","type":"template","z":"3045204d.cfbae","name":"page","field":"payload","fieldType":"msg","format":"handlebars","syntax":"mustache","template":"<html>\n <head></head>\n <body>\n <h1>Hello {{ payload }}!</h1>\n </body>\n</html>","x":290,"y":920,"wires":[["f3c1a3f0.0c3e6"]]},{"id":"f3c1a3f0.0c3e6","type":"http response","z":"3045204d.cfbae","name":"","x":430,"y":920,"wires":[]}]
[~]$ curl -X POST -d 'Nick' -H "Content-type: text/plain" https://:1880/hello-raw
<html>
<head></head>
<body>
<h1>Hello Nick!</h1>
</body>
</html>
讨论
当 HTTP In 节点接收到 Content-Type 标头设置为 text/plain 的请求时，它将请求体作为 msg.payload 提供。
var name = msg.payload;
