如何使用nodejs http API模拟web form表单提交？

Question

现在一个应用需要访问不同域下的TAM安全认证服务，需要模拟form表单提交到WebSEAL，先谢谢了。以下是我目前尝试的http请求写法：varhttp=require('http');varquerystring=require('querystring');varpost_options={host:'192.168.1.22',port:'80',path:'/pkmslogin.form',method:'post',auth:'username:123456','login-form-type':'pwd',headers:{'Content-Type':'application/x-www-form-urlencoded'}};varpost_data=querystring.stringify({username:'username',password:'123456','login-form-type':'pwd'});//Setuptherequestvarpost_req=http.request(post_options,function(res){res.setEncoding('utf8');console.log(JSON.stringify(res.headers));res.on('data',function(chunk){console.log('Response:'+chunk);});});console.log(JSON.stringify(post_req.headers));//postthedata//post_req.write(post_data);post_req.end();

Answer 1

还需注意以下两点：
//1、在头中设置好内容长度
headers:{
'Content-length':post_data.length,
'Content-Type':'application/x-www-form-urlencoded'
}
varpost_data=querystring.stringify({
username:'username',
password:'123456',
'login-form-type':'pwd'
});
//2、参数写入到流中
post_req.write(post_data);
