我使用 Express.js 4.2 版并想解析一个大帖子 (150K - 1M)，但收到错误消息“请求实体太大”。似乎限制是 100 K。我现在不知道如何更改 Express 4 中的限制。在 Express 3.x 中我刚刚做了 -
app.use(express.json({limit: '5mb'}));
app.use(express.urlencoded({limit: '5mb'}));
How can I change the limit in Express 4 ?

With Express 4 you have to install the body-parsermodule and use that instead:
使用 Express 4，您必须安装body-parser模块并使用它：
var bodyParser = require('body-parser');
// ...
app.use(bodyParser.json({limit: '5mb'}));
app.use(bodyParser.urlencoded({limit: '5mb'}));

Mscdex's code works, but we should add another parameter to avoid warning now.
Mscdex 的代码有效，但我们现在应该添加另一个参数以避免警告。
app.use(bodyParser.urlencoded({limit: '5mb', extended: true}));

This is dependent on whether you are receiving data as JSON or via parameterized URL query.
这取决于您是以 JSON 形式接收数据还是通过参数化 URL 查询接收数据。
I had the same problem sending a large JSON buffer. The file was ~ 43KB and I was incoming from my middleware to an express API.
我在发送大型 JSON 缓冲区时遇到了同样的问题。该文件大约为 43KB，我从中间件传入一个快速 API。
I handled it as such:
我是这样处理的：
app.use(bodyParser.json({limit: '5mb'}));
app.use(bodyParser.urlencoded({ extended: false }));
This corrected the issue for me, when the body was a large JSON object.
当主体是一个大型 JSON 对象时，这为我纠正了这个问题。
