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

对我来说，主要的技巧是

app.use(bodyParser.json({
  limit: '20mb'
}));

app.use(bodyParser.urlencoded({
  limit: '20mb',
  parameterLimit: 100000,
  extended: true 
}));

bodyParse。json第一 bodyParse。urlencoded第二

其他回答

2016年，以上都不适合我，直到我显式设置'类型'除了'限制'身体解析器，示例:

  var app = express();
  var jsonParser       = bodyParser.json({limit:1024*1024*20, type:'application/json'});
  var urlencodedParser = bodyParser.urlencoded({ extended:true,limit:1024*1024*20,type:'application/x-www-form-urlencoded' })

  app.use(jsonParser);
  app.use(urlencodedParser);

如果有人尝试了所有的答案，但还没有任何成功，并使用NGINX托管站点，将这一行添加到/etc/nginx/sites-available

client_max_body_size 100M; #100mb

表达4.17.1

app.use( express.urlencoded( {
    extended: true,
    limit: '50mb'
} ) )

以下代码解决了我的问题:

var bodyParser = require('body-parser');
var urlencodedParser = bodyParser.urlencoded({ extended: false, limit: '5mb' });

在我的例子中，添加这些行是不够的:

var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));

我尝试在urlencoded函数上添加parameterLimit选项，正如文档所述，错误不再出现。

parameterLimit选项控制参数的最大数量在url编码的数据中是允许的。如果请求包含更多参数大于此值时，将返回一个413给客户端。默认值为1000。

试试下面的代码:

var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: "50mb"}));
app.use(bodyParser.urlencoded({limit: "50mb", extended: true, parameterLimit:50000}));
