错误:请求实体太大

我收到express的以下错误:

POST /api/0.1/people 500 618ms

I am using meanstack. I have the following use statements in my express.js

//Set Request Size Limit
app.use(express.limit(100000000));

Within fiddler I can see the content-length header with a value of: 1078702

I believe this is in octets, this is 1.0787 megabytes.

I have no idea why express is not letting me post the json array I was posting previously in another express project that was not using the mean stack project structure.

就我而言,Content-type从请求标头中删除是可行的。

就我而言,问题出在Nginx配置上为了解决这个问题,我必须编辑文件:/etc/nginx/nginx.conf并将此行添加到服务器块中:

client_max_body_size 5M;

重新启动Nginx,问题消失了

sudo systemctl restart nginx

稍微不同的方法-有效负载太大

到目前为止,所有有用的答案都涉及增加有效负载限制。但是也可能是有效载荷确实太大但没有充分理由的情况。如果没有正当理由,请考虑一下为什么它这么it肿。

我们自己的经验

例如,在我们的案例中,一个Angular应用正在贪婪地发送有效载荷中的整个对象。当删除一个肿且多余的属性时,有效负载大小减少了100倍这显着提高了性能并解决了413错误。

如果有人尝试了所有答案,但还没有成功,并使用NGINX托管站点,则将此行添加到/ etc / nginx / sites-available

client_max_body_size 100M; #100mb
