我收到此错误:
无法发布/.
以下是我正在尝试执行的代码。
var express = require('express');
var bodyParser = require('body-parser');
var _ = require('underscore');
var db = require('./db.js');
var bcryptjs = require('bcryptjs');
var middleware = require('./middleware.js')(db);
var http = require('http').Server(app);
var app = express();
var PORT = process.env.PORT || 3000;
var todos = [];
var todoNextId = 1;
app.use(express.static(__dirname + '/public'));
app.use(bodyParser.json());
app.get('/', function(req, res) {
res.send('Todo API Root');
});
app.get('/todos', middleware.requireAuthentication, function(req, res) {
var query = req.query;
var where = {
userId: req.user.get('id')
};
if (query.hasOwnProperty('completed') && query.completed === 'true') {
where.completed = true;
} else if (query.hasOwnProperty('completed') && query.completed === 'false') {
where.completed = false;
}
if (query.hasOwnProperty('q') && query.q.length > 0) {
where.description = {
$like: '%' + query.q + '%'
};
}
db.todo.findAll({
where: where
}).then(function(todos) {
res.json(todos);

res.status(500).send();
});
});
app.get('/todos/:id', middleware.requireAuthentication, function(req, res) {
var todoId = parseInt(req.params.id, 10);
db.todo.findOne({
where: {
id: todoId,
userId: req.user.get('id')
}
}).then(function(todo) {
if (!!todo) {
res.json(todo.toJSON());
} else {
res.status(404).send();
}
}, function(e) {
res.status(500).send();
});
});
app.post('/todos', middleware.requireAuthentication, function(req, res) {
var body = _.pick(req.body, 'description', 'completed');
db.todo.create(body).then(function(todo) {
req.user.addTodo(todo).then(function () {

res.send(404).json({
error: 'No todo with id'
});
} else {
res.status(204).send();
}
}, function() {
res.status(500).send();
});
});
app.put('/todos/:id', middleware.requireAuthentication, function(req, res) {
var todoId = parseInt(req.params.id, 10);
var body = _.pick(req.body, 'description', 'completed');
var attributes = {};
if (body.hasOwnProperty('completed')) {
attributes.completed = body.completed;
}
if (body.hasOwnProperty('description')) {
attributes.description = body.description;
}
db.todo.findOne({
where: {
id: todoId,

}
}).then(function(todo) {
if (todo) {
todo.update(attributes).then(function(todo) {
res.json(todo.toJSON());
}, function(e) {
res.status(400).json(e);
});
} else {
res.status(404).send();
}
}, function() {
res.status(500).send();
});
});
app.post('/users', function(req, res) {
var body = _.pick(req.body, 'email', 'password');
db.user.create(body).then(function(user) {
res.json(user.toPublicJSON());
}, function(e) {
res.status(400).json(e);
});
});
app.post('/users/login', function (req, res) {
var body = _.pick(req.body, 'email', 'password');
var userInstance;
db.user.authenticate(body).then(function (user) {
var token = user.generateToken('authentication');
userInstance = user;
return db.token.create({
token: token
});
}).then(function (tokenInstance) {
res.header('Auth',
tokenInstance.get('token')).json(userInstance.toPublicJSON());
}).catch(function () {
res.status(401).send();
});
});
app.delete('/users/login', middleware.requireAuthentication,
function (req, res) {
req.token.destroy().then(function () {
res.status(204).send();
}).catch(function () {
res.status(500).send();
});
});
db.sequelize.sync({force: true}).then(function() {
app.listen(PORT, function() {
console.log('Express listening on port ' + PORT + '!');
});
});
这是我的app.js文件
app.post('/users', function(req, res) {
var body = _.pick(req.body, 'email', 'password');
db.user.create(body).then(function(user) {
res.json(user.toPublicJSON());
}, function(e) {
res.status(400).json(e);
});
});
我一直在尝试这个但没有通过。不确定我的html文件是否正确。想要创建一个html文件来发布,但我的拒绝回复。
答案 0 :(得分:2)
您不能toLocalIterator
到POST
,因为您尚未为/
POST
的{{1}}请求定义路由处理程序(您只有一个/
来自GET
)。
