POST /api/0.1/people 500 618ms

我用的是meanstack。我有以下使用语句在我的express.js

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

在fiddler中,我可以看到内容长度头的值为:1078702

我想这是八位字节,这是1.0787兆字节。

我不知道为什么express不让我发布json数组,我之前在另一个express项目中发布,该项目没有使用平均堆栈项目结构。


当前回答

在我的例子中,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,并在服务器块中添加这一行:

client_max_body_size 5M;

重新启动Nginx,问题就消失了

sudo systemctl restart nginx

其他回答

一个稍微不同的方法——有效载荷太大了

到目前为止,所有有用的答案都涉及增加有效载荷限制。但也可能是载荷确实太大了,但没有好的理由。如果没有合理的理由,那么首先考虑一下为什么它会如此膨胀。

我们自己的经验

例如,在我们的例子中,一个Angular应用贪婪地在有效负载中发送了整个对象。当删除一个臃肿和冗余的属性时,有效负载大小减少了100倍。这极大地提高了性能并解决了413错误。

就我而言…setting parameterLimit:50000修复了这个问题

app.use( bodyParser.json({limit: '50mb'}) );
app.use(bodyParser.urlencoded({
  limit: '50mb',
  extended: true,
  parameterLimit:50000
}));

只要加上这一行就能解决问题

app.use(express.json({limit: '50mb'}));

还建议大家将整个图像发送到后端,然后转换它,而不是从前端发送数据

我也面临着这个问题,我犯了一个愚蠢的错误,重复了app.use(bodyParser.json()),如下所示:

app.use(bodyParser.json())
app.use(bodyParser.json({ limit: '50mb' }))

通过删除app.use(bodyParser.json()),解决了这个问题。

将以下配置传递给服务器以增加请求大小。

app.use(express.json({ extended: false, limit: '50mb' }))
app.use(express.urlencoded({ limit: '50mb', extended: false, parameterLimit: 50000 }))
