我在PUT请求上收到HTTP 404,如下所示:
$(function(){
$("#showMovies").click(function() {
$.ajax({

因此,每当我尝试执行我的放置请求时,总是会收到找不到状态码404的错误,并且我的发布和删除工作也很好,这只是我的放置请求,我可以做什么来解决它。另外,由于我忘记添加功能,因此我也可以在Web浏览器中使用它
app.put('/movielist/id',(req,res) =>{
let update = req.body;
mysqlConnection.query("UPDATE movielist SET year_released = '2000' WHERE idmovielist = '6'",
[update.year_released, update.idmovielist,req.params.id],
(err, results) => {
if (!err) {
res.send("Movie list is updated");
} else {
console.log(err);
}
});
});
也是我的发帖请求代码
app.post('/movielist/addMovie',(req, res) => {
mysqlConnection.query("INSERT INTO movielist (idmovielist, name, thumnail_path, description, year_released,language_released) VALUES ('10', 'Bubble Gum', 'yourieiri.jpg', 'Disturbing', '2007', 'french');",
req.body,
(err,rows) => {
if (!err) {
res.send("Movie is added");
} else {
console.log(err);
}
});
});
app.get('/movielist',(req,res)=> {
mysqlConnection.query("SELECT * FROM movielist", (err, rows,fields)=> {
if (!err) {
res.send(rows);
} else {
console.log(err);
}
});
});
app.delete('/movielist/:id',(req,res) => {
mysqlConnection.query("DELETE FROM movielist WHERE idmovielist = ?",[req.params.id],(err,rows,fields) =>{
if (!err) {
res.send("Movie is deleted");
} else {
console.log(err);
}
});
});
app.post('/movielist/addMovie',(req, res) => {
mysqlConnection.query("INSERT INTO movielist (idmovielist, name, thumnail_path, description, year_released,language_released) VALUES ('10', 'Bubble Gum', 'yourieiri.jpg', 'Disturbing', '2007', 'french');",
req.body,
(err,rows) => {
if (!err) {
res.send("Movie is added");
} else {
console.log(err);
}
});
});
app.put('/movielist/:id',(req,res) =>{
let update = req.body;
mysqlConnection.query("UPDATE movielist SET year_released = '2000' WHERE idmovielist = '6'",
[update.year_released, update.idmovielist,req.params.id],
(err, results) => {
if (!err) {
res.send("Movie list is updated");
} else {
console.log(err);
}
});
});
答案 0 :(得分:0)
I think you need to change this:
app.put('/movielist/id',(req,res) =>{
to this:
app.put('/movielist/:id',(req,res) =>{
In nodejs with express framework, in order to use /link/parameter/, parameter needs to be declared with :.
