exports.postImportHomeworkAnnotations = async (req, res, next) =>{

const homework_id = req.body.homework_id;
const pag = parseInt(req.body.page);
const user = req.session.user;
const userTaget = req.body.user_target;
if(homework_id && pag ){
let compito = await CompitiModel.findById({_id : homework_id})
.populate('risultati.risultati')
if(compito.owner.user.toString() === user.objectId.toString()){
for (let i = 0; i < compito.risultati.length; i++) {
if(compito.risultati[i].risultati.owner.user.toString() === userTaget.toString() && compito.risultati[i].risultati.editable){
compito.risultati[i].risultati.blob_annotation.forEach(ele =>{
if(ele.page === pag){
//WHEN I RETURN HERE
return res.json({data : ele.blob_annotation});
}
})
//EXECUTE EVEN THAT
return res.json({data : {}});
}
}
}else{
//......
//..........
}
}
}
如何在第一次返回时正确返回并中断功能? 在该示例中,当我到达第一个返回时,代码将继续运行,甚至尝试使用res执行第二个返回,这会出错->错误:发送标头后无法设置标头。
