【问题描述】:
我收到此错误,但找不到任何原因。
我已在 amazon aws 上部署了此代码。是因为代码的异步执行吗? Stackoverflow 说我要添加更多细节,但我没有更多。
以下是我的代码快照。
"Error: write EPIPE
at Object.exports._errnoException (util.js:870:11)
at exports._exceptionWithHostPort (util.js:893:20)
at WriteWrap.afterWrite (net.js:763:14)"
module.exports.register = function(client, body, s, rclient, redis, callback){
console.log("inside registration module function");
console.log(body);
console.log("mobile no", body.mobile_no);
client.connectAsync()
.then(()=>
{
return client.queryAsync('select count(*) from users where mobile_no=$1',[body.mobile_no]);})
.then(res=>{
console.log("connection successful");
if(res.rows[0].count==0)
{
return client.queryAsync('insert into users(mobile_no, email, city, uname, password) values ($1, $2, $3, $4, $5)', [body.mobile_no, body.email, body.city, body.uname, body.password])
.then(()=>{
return client.queryAsync('select uid from users where mobile_no=$1',[body.mobile_no]);
})
.then(res=>{
var uid = JSON.stringify(res);
uid = JSON.parse(uid).rows[0].uid;
console.log("uid: ", uid);
console.log(uid);
console.log(s);
rclient.set(s,uid,redis.print);
const response = {
statusCode:201,
body: JSON.stringify({
sid: s,
message: 'user registered',
}),
};
console.log('success');
return Promise.promisify(response);
})
.then(res=>{
callback(null, res);
})
}
else
{
console.log("It is already registered mobile no");
const response = {
statusCode:412,
body: JSON.stringify({
sid: '',
message: 'error: mobile no already registered',
}),
};
Promise.promisify(response);
}
})
.then(res=>{
callback(null, res);
})
.then(()=>{
client.end();
rclient.quit();
})
.catch(err=>{
console.log(err.stack);
console.log("error occured");
})
}
【问题讨论】:
-
该错误是在哪里产生的?
-
管道到关闭的流时引发 EPIPE 错误
-
是你的节点版本
-
我的节点版本是v4.3.2。 api有时会正常执行。但是,有时它会给出上述错误
