Answer 1

您可以像这样发送

const resize = (filepath: string, output: string, width: number = 256, height: number = 256) => {
  const proc = spawn("gm", ["convert", filepath, "-resize", `${width}x${height}`, output]);

  return new Promise((resolve, reject) => {
    let err = "";
    proc.stderr.on("data", chunk => {
      err += chunk.toString();
    });

    const onEnd = (code: number) => (code ? reject(err) : resolve());

    proc.on("close", onEnd);
    proc.on("end", onEnd);
  });
};

resize("C:/Users/Desktop/file.jpg", "C:/Users/Desktop/sfile.jpg");

将middleware插入管道：

app.Use(async (context, next) =>
{
    context.Response.Headers.Add("Time-Allow-Origin", new[] { "value1", "value2", "value3" });

    await next();
});
