最近想系统学习一下express，所以找来大师的《Node与Express》膜拜，问题不少，记录下来，供大家参考交流： 1 模板渲染上下文的赋值 res.locals 是这么个情况： 模板文件views/partials/weather.hbs <div class="weatherWidget"> {{#each partials.weather.locations}} <div class="location"> <h3>{{name}}</h3> <a href="{{forecastUrl}}"> <img src="{{iconUrl}}" alt="{{weather}}"> {{weather}}, {{temp}} </a> </div> {{/each}} <small>Source: <a href="http://www.wunderground.com">Weather Underground</a></small> </div> 应用文件meadowlark.js /* 给res.locals.partials对象添加数据的中间件 */ app.use(function(req, res, next){ if(!res.locals.partials) res.locals.partials = {}; res.locals.partials

Using Express.js and NodeJS, Can you send JSON via redirect in the response body
