CI中使用phpqrcode问题
请问下 我使用phpqrcode 来生成二维码时, 直接在controllers目录的文件下 能正常生成, 但是调用模型在模型里调用QRcode::png()函数就生成不了, 什么原因呢?
回复讨论(解决方案)
你在模板中是怎么写的?
QRcode::png() 得到的是图片数据流
我是直接写的 QRcode:png() 然后就输不出二维码
什么原因呢? 大神指教呀
让你告诉我你是怎么写的,就那么难吗?
QRcode::png("http://www.baidu.com"); 就这样
就这一句???
对 测试用的 所以写的简单的
public function test(){
QRcode::png("http://www.baidu.com");
}
你自己都说了 直接在controllers目录的文件下 能正常生成, 但是调用模型在模型里调用QRcode::png()函数就生成不了
那你不给看是怎么调用的,怎么找问题?
难道你认为是 QRcode::png("http://www.baidu.com"); 本身错了?
调用是直接controllers 下的文件里调用的 调用函数
public function test(){
// QRcode::png("http://www.baidu.com"); // 这样可以直接输出
Modules::load('ayment_gateway/payment_gateway)->test(); // 调用后就不可以
}
Modules::load('ayment_gateway/payment_gateway)->test(); 输出的是什么?

看到了吧?有BOM 头!
