刚刚试了一下,在openresty.1.2.7.5下有问题
*45 writev() failed (22: Invalid argument), client: 10.68.143.131, server: 10.66.23.99, request: "GET /qrcode?size=6&fg_color=00FF00&bg_color=fff700&case=1&txt=12a&margin=2&level=0&hint=2&ver=3 HTTP/1.1", host: "10.66.23.99"
在1.2.6.3下则无问题,估计是nginx1.2.6和nginx 1.2.7的区别,不知道哪里有冲突了
