Espruino HTTP POST

More than 1 year has passed since last update.

Espruino で HTTP GET リクエストは例があるので簡単にできる。POST でデータ送信する例がなかったので、調べたメモ。

var data = JSON.stringify({"metrics1":10.0});
var request = require("http").request(
    {host:"harvest.soracom.io", method:"POST", path:"/", headers:{
        "content-type":"application/json",
        "content-length": data.length,
        "connection":"close"
    }},
    response=>{
        var content = "";
        response.on("data", data=>{
            content += data;
        });
        response.on("close", ()=>{
            console.log(content);
        });
        response.on("error", err=>{
            console.log("error", err);
        });
    });
request.write(data);
request.end();

Content-length は、サーバ側の実装の都合上、たいてい必要になる。Connection: close は、開発時サーバが single thread の時のための安全設定。
