Codeigniter 重定向 returns 字符串而不是将其传递给 url

Question

这是我使用 ajax 登录的控制器。 Login.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login extends CI_Controller {

public function index(){
    $this->load->view('login');
}

public function checkLogin(){
    if($this->input->is_ajax_request() && isset($_POST['email']) && isset($_POST['password'])){#restrict direct access from browser
        if(empty($this->input->post('email')) || empty($this->input->post('password'))){
            echo "not";
        }else{
            if(filter_var($this->input->post('email'), FILTER_VALIDATE_EMAIL) === false){
                echo "not";
            }else{
                $data = array(
                        'email' => $this->input->post('email'),
                        'password' => md5($this->input->post('password'))
                    );
                if($this->db->select('*')&&
                $this->db->from('users')&&
                $this->db->where($data)){
                    if($this->db->count_all_results() > 0){
                        redirect('homepage'); #REDIRECT
                    }else{
                        echo "not";
                    }
                }

            }
        }

    }else{
        show_error("No direct script access allowed");
    }
}
}

这是我的 javascript 文件：

$(document).ready(function(){
$("#login-form").submit(function(event){
    event.preventDefault();
    $.ajax({
        url: 'http://citest.local/login/checkLogin',
        type: 'POST',
        data: {
                email: $.trim($("#email").val()),
                password: $.trim($("#password").val())},
    })
    .done(function(result) {
        if(result == "not"){
            $(".has-feedback").addClass('has-error');
            $(".glyphicon").addClass('glyphicon-remove');
        }else{
            $(".has-feedback").removeClass('has-error');
            $(".glyphicon").removeClass('glyphicon-remove');
            $(".has-feedback").addClass('has-success');
            $(".glyphicon").addClass('glyphicon-ok');
            console.log(result);
        }
    });
});
});

这是我控制器的重定向功能返回到控制台的结果：

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title>Simple Contacts</title>
<link rel="stylesheet" href="">
</head>
<body>

</body>
</html>

.htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# Disable rewrite for valid directory/files     
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d 

#map all request urls to a specific controller method
RewriteRule ^(.*)$ index.php?/{controller}/{method}/ [L]
</IfModule>

<IfModule !mod_rewrite.c>
  # If we don't have mod_rewrite installed, all 404's
  # can be sent to index.php, and everything works as normal.
  # Submitted by: ElliotHaughin

  ErrorDocument 404 /index.php
</IfModule>

站点配置 (nginx)

server {
    listen 80;

    root /home/user/trytry/ci_test;
    index index.html index.htm index.php;

# Make site accessible from http://localhost/
server_name citest.local;

# unless the request is for a valid file (image, js, css, etc.), send to bootstrap
if (!-e $request_filename)
{
    rewrite ^/(.*)$ /index.php?/ last;
    break;
}   

location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to displaying a 404.
    try_files $uri $uri/ =404;
    # Uncomment to enable naxsi on this location
    # include /etc/nginx/naxsi.rules
}

# Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
#location /RequestDenied {
#   proxy_pass http://127.0.0.1:8080;    
#}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html
#
#error_page 500 502 503 504 /50x.html;
#location = /50x.html {
#   root /usr/share/nginx/html;
#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini

    # With php5-cgi alone:
#   fastcgi_pass 127.0.0.1:9000;
    # With php5-fpm:
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
#   deny all;
#}
}

为什么重定向不能正常工作？它 returns 字符串而不是重定向 url。请帮忙！ :(

Answer 1

AJAX 不是为那样工作而设计的。您的重定向代码

redirect('homepage'); #REDIRECT

将您的 ajax 请求重定向到该页面，然后该页面从主页视图获取信息，然后将其作为 AJAX 响应传回。

如果你想重定向，你应该通过AJAX传回一个成功或失败的消息，然后使用JavaScript在浏览器中重定向

Codeigniter 重定向 returns 字符串而不是将其传递给 url

Codeigniter redirect returns string instead of passing it to the url

php

ajax

.htaccess
