使用Cloudinary的URL API时，是否存在最大转换次数或最大URL长度？

Question

我尝试使用Cloudinary构建我的opengraph图像，并进行一些转换以添加文本。

这就是我试图做的事情：

https://res.cloudinary.com/nho/image/fetch/e_blur:2000,c_crop,ar_1200:630,b_white/e_grayscale/w_1200/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vMjAxNy8xMC9jaHJvbWUtZW1vamktMTI4cHgtbWF4LnBuZw==,h_1.0,w_1.0,fl_relative,c_limit/b_rgb:3d2e68,o_40/w_1120,c_fit,l_text:georgia_80:Chrome%20fails%20showing%20big%20emojis,g_north_west,x_42,y_43,co_black,o_50/w_1120,c_fit,l_text:georgia_80:Chrome%20fails%20showing%20big%20emojis,g_north_west,x_41,y_42,co_black,o_75/w_1120,c_fit,l_text:georgia_80:Chrome%20fails%20showing%20big%20emojis,g_north_west,x_40,y_40,co_white/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vYXNzZXRzL3Bob3RvLWRlLW5pY29sYXMtaG9pemV5LmpwZw==,g_south_west,x_40,y_40,c_fill,w_60,r_max/l_text:georgia_50:nicolas-hoizey.com,g_south_west,x_112,y_40,co_black/l_text:georgia_50:nicolas-hoizey.com,g_south_west,x_111,y_41,co_white/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vYXNzZXRzL2xvZ29zL3R3aXR0ZXIucG5n,g_south_east,x_220,y_40,c_fill,w_50,r_max/l_text:georgia_50:nhoizey,g_south_east,x_40,y_40,co_black/l_text:georgia_50:nhoizey,g_south_east,x_41,y_41,co_white/https://nicolas-hoizey.com/2017/10/chrome-emoji-128px-max.png

我知道语法很好，但我收到400 Bad Request错误。

如果我删除了添加文本的最后一个转换（/l_text:georgia_50:nhoizey,g_south_east,x_41,y_41,co_white），它就会起作用：

https://res.cloudinary.com/nho/image/fetch/e_blur:2000,c_crop,ar_1200:630,b_white/e_grayscale/w_1200/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vMjAxNy8xMC9jaHJvbWUtZW1vamktMTI4cHgtbWF4LnBuZw==,h_1.0,w_1.0,fl_relative,c_limit/b_rgb:3d2e68,o_40/w_1120,c_fit,l_text:georgia_80:Chrome%20fails%20showing%20big%20emojis,g_north_west,x_42,y_43,co_black,o_50/w_1120,c_fit,l_text:georgia_80:Chrome%20fails%20showing%20big%20emojis,g_north_west,x_41,y_42,co_black,o_75/w_1120,c_fit,l_text:georgia_80:Chrome%20fails%20showing%20big%20emojis,g_north_west,x_40,y_40,co_white/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vYXNzZXRzL3Bob3RvLWRlLW5pY29sYXMtaG9pemV5LmpwZw==,g_south_west,x_40,y_40,c_fill,w_60,r_max/l_text:georgia_50:nicolas-hoizey.com,g_south_west,x_112,y_40,co_black/l_text:georgia_50:nicolas-hoizey.com,g_south_west,x_111,y_41,co_white/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vYXNzZXRzL2xvZ29zL3R3aXR0ZXIucG5n,g_south_east,x_220,y_40,c_fill,w_50,r_max/l_text:georgia_50:nhoizey,g_south_east,x_40,y_40,co_black/https://nicolas-hoizey.com/2017/10/chrome-emoji-128px-max.png

这是否意味着我在一个网址中堆叠了太多的转换？

更新

我后来尝试减少第一个文本的长度（添加3次以创建阴影），从Chrome%20fails%20showing%20big%20emojis到Chrome%20fails，它也有效：

https://res.cloudinary.com/nho/image/fetch/e_blur:2000,c_crop,ar_1200:630,b_white/e_grayscale/w_1200/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vMjAxNy8xMC9jaHJvbWUtZW1vamktMTI4cHgtbWF4LnBuZw==,h_1.0,w_1.0,fl_relative,c_limit/b_rgb:3d2e68,o_40/w_1120,c_fit,l_text:georgia_80:Chrome%20fails,g_north_west,x_42,y_43,co_black,o_50/w_1120,c_fit,l_text:georgia_80:Chrome%20fails,g_north_west,x_41,y_42,co_black,o_75/w_1120,c_fit,l_text:georgia_80:Chrome%20fails,g_north_west,x_40,y_40,co_white/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vYXNzZXRzL3Bob3RvLWRlLW5pY29sYXMtaG9pemV5LmpwZw==,g_south_west,x_40,y_40,c_fill,w_60,r_max/l_text:georgia_50:nicolas-hoizey.com,g_south_west,x_112,y_40,co_black/l_text:georgia_50:nicolas-hoizey.com,g_south_west,x_111,y_41,co_white/l_fetch:aHR0cHM6Ly9uaWNvbGFzLWhvaXpleS5jb20vYXNzZXRzL2xvZ29zL3R3aXR0ZXIucG5n,g_south_east,x_220,y_40,c_fill,w_50,r_max/l_text:georgia_50:nhoizey,g_south_east,x_40,y_40,co_black/l_text:georgia_50:nhoizey,g_south_east,x_41,y_41,co_white/https://nicolas-hoizey.com/2017/10/chrome-emoji-128px-max.png

所以我怀疑URL长度可能是个问题。

Answer 1

问题不在于每个网址的转化次数。问题是转型本身太长了。请考虑使用named transformations来缩短它。
