访问node服务器跨域,post请求变成了options,设置请求头后,获取不到post请求提交的数据
var http = require('http');
var url = require("url");
http.createServer(function (req, res) {
var urlObj = url.parse(req.url);
var pathname = urlObj.pathname;
// 关闭nodejs 默认访问 favicon.ico
if (!pathname.indexOf('/favicon.ico')) {
return;
};
let requestM=req.method;
res.writeHeader(200,{
"access-control-allow-origin": "*",
"access-control-allow-methods": "GET, POST, PUT, DELETE, OPTIONS",
"access-control-allow-headers": "Content-Type,Content-Length, Authorization, Accept,X-Requested-With",
"access-control-max-age": 10,
"Content-Type": "application/json"
});
if(requestM==="POST"){
var post = '';
// 通过req的data事件监听函数,每当接受到请求体的数据,就累加到post变量中
req.on('data', function(chunk){
post += chunk;
});
}
//获取不到post 请求过来的参数
}).listen(3000);
怎么post数据的,贴出来看下
另外我觉得在res写头没有必要写allow header 你的需求要求这么高吗
