A collection of simple demos of Koa
实例代码
const main = cxt =>{
cxt.throw(500);
}
改为
const main = cxt =>{
cxt.response.status = 500;
}
下面代码运行不到
app.on('error', (err, cxt) =>{
console.error('server error', err);
});
curl是linux的命令,这里假如我模拟一个Post请求,请求本地的3000端口,,请求为files: 本地的文件的真是路径(例如C:\Users\xx\Desktop\koa-demos-master.zip),
const files = ctx.request.body.files || {} 就是直接拿到了 C:\Users\xx\Desktop\koa-demos-master.zip这个路径了,然后下面又是遍历,,结果下面 又对这个files遍历了
const
filePath = path.join(tmpdir,file.name)
file.name肯定会是undefined,然后文件肯定是不能上传,我想问的就是在windows上这个例子该怎么写啊?如何更好然后模拟测试呢?不知道怎么写?
127.0.0.1:3000
文档最后一段:
Usefule Links
拼写有误,应该为 Useful Links
代码
const Koa = require('koa');
const fs = require('fs.promised');
const app = new Koa();
const main = async function (ctx, next){
ctx.response.type = 'html';
ctx.response.body = await fs.readFile('./demos/template.html', 'utf8');
}
app.use(main);
app.listen(3000);
报错

运行环境:ARM VPS + ubuntu
运行 $ docker image build -t koa-demo . 之后,提出如下错误:
[Warning] The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
是否可以看下怎么解决,谢谢。
现在首先判断xml,返回xml,
习惯默认返回html
所以建议把html放在第一个判断
