我正在通过ajax将Image base64数据传递给我的php函数,但是对于大尺寸图像,Ajax不会发布数据。但是,相同的代码对于小图像非常适用。

数据太大,因此部分发布了,
ajax
count = 1; name='test' jQuery.ajax({ url:"/createImage.php", data:{img_data:srcdata,img_id:count,name:name}, type:"POST", contentType:"application/x-www-form-urlencoded", success:function(result) { alert(result); } });
PHP
print_r($_POST); // is empty when logging..
当我尝试获取php中的发布数据时,我越来越空了。使用base64时,ajax不发送数据的原因可能是什么?
我同意TrueBlueAussie的观点。这看起来像PHP中的服务器端设置。
打开php.ini文件,然后找到行upload_max_filesize。默认设置为2M,即2MB。尝试将其增加到3MB,然后查看是否仍然收到错误。
php.ini
upload_max_filesize
注意:您需要重新启动Apache / Nginx / webserver才能从php.ini文件中生效。
即使您将文件作为变量发送,application/x-www-form- urlencoded也可能在PHP中将其解释为实际的文件上传。php.ini您可以查看的另一个设置post_max_size是默认设置8M,这是您可以发布到PHP脚本的最大值。
application/x-www-form- urlencoded
post_max_size
