        })
        .fail(function() {

在Web服务器（Ubuntu 14.04上的Apache 2.4）http://www.mysite1.org/ ....我已经用这种方式修改了我的apache2.conf文件....

<Directory /var/www/cesarefortelegram>
        Order Allow,Deny
        Allow from all
        AllowOverride all
        Header set Access-Control-Allow-Origin "*"
</Directory>

按照这些说明How to allow Cross domain request in apache2。

我的网络浏览器控制台（网络标签..）

中仍然出现以下错误

Failed to load http://www.mysite1.org/cesarefortelegram/Telegram/OpenProntoSoccorso/API/getProntoSoccorsoDetailsByMunicipality.php?&municipality=Torino&distance=0: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.mysite2.com' is therefore not allowed access.

我在哪里做错了？

提前致谢

Answer 1

我发现我的apache2.conf文件中有错误....

这是正确的配置（忘了＆＃34; html＆＃34;＆＃34; www＆＃34;对不起......）......

<Directory /var/www/html/cesarefortelegram>
        Order Allow,Deny
        Allow from all
        AllowOverride all
        Header set Access-Control-Allow-Origin "*"
</Directory>

现在一切正常......

Answer 2

对我有用的Ubuntu Apache2解决方案 .htaccess编辑对我不起作用，我不得不修改conf文件。

nano /etc/apache2/sites-available/mydomain.xyz.conf

<IfModule mod_ssl.c>
    <VirtualHost *:443>

        ServerName mydomain.xyz
        ServerAlias www.mydomain.xyz

        ServerAdmin support@mydomain.xyz
        DocumentRoot /var/www/mydomain.xyz/public

        ### following three lines are for CORS support
        Header add Access-Control-Allow-Origin "*"
        Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
        Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        SSLCertificateFile /etc/letsencrypt/live/mydomain.xyz/fullchain.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/mydomain.xyz/privkey.pem

    </VirtualHost>
</IfModule>

然后键入以下命令
