curl: (26) couldn't open file
提问by halkujabra
I am getting this error, when I am trying to call a box api through curl.
当我尝试通过 curl 调用 box api 时，出现此错误。
curl: (26) couldn't open file
Can't find why! I am calling this api with a correct file name-
找不到原因！我用正确的文件名调用这个 api-
curl https://upload.view-api.box.com/1/documents \
-H "Authorization: Token YOUR_API_TOKEN" \
-H "Content-type: multipart/form-data" \
-F file=@A_correct_file_name
I have seen all the three already asked questions but 2 of them are unanswered and one is specific to facebook.
我已经看到了所有三个已经问过的问题，但其中两个没有答案，一个是特定于 facebook 的。

Sorry guys! My bad. I had not included extension of the file in the file name. After including it, it worked. I am answering this in case someone does the same mistake in future.
对不起大家！我的错。我没有在文件名中包含文件的扩展名。包含它后，它起作用了。我正在回答这个问题，以防将来有人犯同样的错误。

I was having a similar problem after changing to PHP 5 (I was using the @upload method and it was deprecated, so I had to start using CURLFile), and the solution to my problem was found in this stack.
改用PHP 5后也遇到了类似的问题（我用的是@upload方法，已经弃用了，所以不得不开始使用了CURLFile），我的问题的解决方法是在这个stack中找到的。
Solution:curl upload won't work with relative paths, use the full path instead
解决方案：curl 上传不适用于相对路径，请改用完整路径

I was having this problem this morning but I solved with this
我今天早上遇到了这个问题，但我解决了这个问题
fileUpload=@\"file, with comma .txt\"
So you have to put some double quotes around the file name if you have commas in the file name ( \" )
因此，如果文件名中包含逗号（ \" ），则必须在文件名周围加上一些双引号

For my case, using relative path didn't work. But changing it to a absolute path fixes it.
就我而言，使用相对路径不起作用。但是将其更改为绝对路径可以修复它。
This failed
这失败了
curl -i -X POST -H "Content-Type: multipart/form-data" \
-F "file=@~/Downloads/xxx.csv" http://localhost:6708/upload
This worked
这有效
curl -i -X POST -H "Content-Type: multipart/form-data" \
-F "file=@/Users/myself/Downloads/xxx.csv" http://localhost:6708/upload

I had a similar problem with relative paths like @Guilherme did too. I was running my bash script with:
我在相对路径方面也有类似的问题，比如@Guilherme。我正在运行我的 bash 脚本：
bash test/script.sh
However, my file was in the same directory level as the bash script and not the testdirectory (where I was calling bash from), so the script could not find my file.
但是，我的文件与 bash 脚本位于同一目录级别，而不是test目录（我从中调用 bash 的位置），因此脚本找不到我的文件。
Solution for me:
1. cd into /test and run bash script.sh from there
2. Use absolute paths
我的解决方案：
1. cd 进入 /test 并从那里运行 bash script.sh
2. 使用绝对路径

Luis Cruz is correct: quotes are required around the filename, but I needed to use the 'file' keyword, not 'fileUpload', as is it shown in the question.
Luis Cruz 是正确的：文件名周围需要引号，但我需要使用“file”关键字，而不是“fileUpload”，如问题所示。
curl -X GET \
-H 'Content-Type: multipart/form-data' \
-F file=@"/path/to/file.ext" \
'http://host:port/path/to/dir'
