ctx中的body无法找到

学习koa的时候看到廖雪峰大大的文章 其中有一段写的总是报错找不到name

代码如下

router.get('/', async (ctx, next) => {
    ctx.response.body = `
Index
        

            
Name: 
            
Password: 
            

        
`;
});

router.post('/signin', async (ctx, next) => {
    var
        name = ctx.request.body.name || '',
        password = ctx.request.body.password || '';
    console.log(`signin with name: ${name}, password: ${password}`);
    if (name === 'koa' && password === '12345') {
        ctx.response.body = `
Welcome, ${name}!
`;
    } else {
        ctx.response.body = `
Login failed!
        
Try again
`;
    }
});

 经过一番调试终于找到报错的原因 因为每个函数中少了

await next();

 

所以修改后的代码为

router.get('/', async (ctx, next) => {
    await next();
    ctx.response.body = `
Index
        

            Name: 
            Password: 
            
        
`;
        
});

router.post('/signin', async (ctx, next) => {
    await next();
    var
        name = ctx.request.body.name || '',
        password = ctx.request.body.password || '';
    console.log(`signin with name: ${name}, password: ${password}`);
    if (name === 'koa' && password === '12345') {
        ctx.response.body = `
Welcome, ${name}!
`;
    } else {
        ctx.response.body = `
Login failed!
        
Try again
`;
    }
    
});
