我正在Node.js Express中创建一个API,它可能会收到大量请求.我真的很想知道请求有多大.
//....
router.post('/apiendpoint',function(req,res,next) {
console.log("The size of incoming request in bytes is");
console.log(req.????????????); //How to get this?
});
//....
解决方法
您可以使用req.socket.bytesRead,也可以使用
request-stats模块.
var requestStats = require('request-stats');
var stats = requestStats(server);
stats.on('complete',function (details) {
var size = details.req.bytes;
});
详细信息对象如下所示：
{
ok: true,// `true` if the connection was closed correctly and `false` otherwise
time: 0,// The milliseconds it took to serve the request
req: {
bytes: 0,// Number of bytes sent by the client
headers: { ... },// The headers sent by the client
method: 'POST',// The HTTP method used by the client
path: '...' // The path part of the request URL
},res : {
bytes: 0,// Number of bytes sent back to the client
headers: { ... },// The headers sent back to the client
status: 200 // The HTTP status code returned to the client
}
}
因此,您可以从details.req.bytes获取请求大小.
另一个选项是req.headers [‘content-length’](但有些客户端可能不会发送此标头).
