Ajax找不到网址 [英] Ajax not finding url

问题描述

我一直在研究的一个简短问题，但似乎无法解决.

Quick question I have been working at but can't seem to get it fixed.

我有一个ajax调用，但是它没有从php文件中得到响应，它似乎正在加载404.

I have a ajax call but it is not getting a response from the php file, it seems to be loading a 404 instead.

地址栏中的网址为"mydomain.com/checkcity/"

The url in the address bar is "mydomain.com/checkcity/"

带有ajax的文件的位置是"/php/advert/script.php"

The location of the file with the ajax is "/php/advert/script.php"

要调用的php文件的位置为"/php/advert/available.php"

The location of the php file to be called is "/php/advert/available.php"

我通过htaccess使用虚拟网址.

I am using virtual urls through the use of htaccess.

这是我的ajax调用:

Here is my ajax call:

    $.ajax({
        type: "POST",
        url: "/available.php",
        data: "city="+city,
        success: function(response){
        alert(response);
}
});

这是我的htaccess文件:

Here is my htaccess file:

    <IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

</IfModule>

我注意到的一件事是，当我在地址栏中搜索url时，它将加载php文件，而不仅仅是使用ajax调用.

One thing I noticed is when I search the url in the address bar it will load the php file just not with the ajax call.

我目前正在Apache 2.2本地主机上运行它

I am running this currently on Apache 2.2 localhost

谢谢您的建议.

推荐答案

我假设您在浏览器的错误日志/控制台中看到了 404 错误消息?它还应该显示正在返回 404 响应的 URL ，根据您的请求，该响应将是: http://www.mysite.com/available.php .

I'm assuming that you're seeing the 404 error message in the error log/console for your browser? It should also be displaying the URL that is returning the 404 response which, given your request, would be: http://www.mysite.com/available.php.

问题是您的ajax调用在 URL 参数的开头包含一个/.这表示网站的根域(即，它指向 http://www.mysite.com/available.php ).

The problem is that your ajax call contains a / at the start of the URL parameter. This signifies the root domain of the website (i.e. it points to http://www.mysite.com/available.php).

url: "/available.php",

解决方案

只需将url参数更改为以下正确 URL s

url: "http://www.mysite.com/php/advert/available.php",

OR

url: "/php/advert/available.php",

OR

url: "available.php",

OR

url: "./available.php",

---

说明代码

$.ajax({
    type: "POST",
    url: "/php/advert/available.php",
    data: "city="+city,
    success: function(response){
        alert(response);
    }
});
