【问题描述】：

我尝试使用 Cloudinary 构建我的 opengraph 图像，并通过一些转换来添加文本。

这是我尝试做的：

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 URL 中堆叠了太多转换？

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，它也起作用了：

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 长度可能是问题所在。

【问题讨论】：

标签： cloudinary http-error

【解决方案1】：

问题不在于每个 URL 的转换次数。问题是转换本身太长了。请考虑使用named transformations 来缩短它。

【讨论】：

你的意思是整个转换，基于几个转换？命名转换是个好主意，我会看看我能为始终相同的转换做什么。
是的，整个转换（所有转换组件组合在一起）。祝你好运:)
我删除了一些转换，它可以工作，谢谢。
