Powershell curl 双引号

Question

I am trying to invoke a curl command in powershell and pass some JSON information.

Here is my command:

curl -X POST -u username:password -H "Content-Type: application/json" -d "{ "fields": { "project": { "key": "key" }, "summary": "summary", "description": "description - here", "type": { "name": "Task" }}}"

I was getting globbing errors and "unmatched braces" and host could not be resolved, etc.

Then I tried prefixing the double quotes in the string with the backtick character, but it could not recognize the - character in the description json field

thanks

EDIT 1:

When I wrote the curl command in a regular batch file, I used double quotes and no single quotes. Also, in the -d string, I escaped all the double quotes with \\ and the command worked.

In this case, my curl is actually pointing to curl.exe. I specified the path, just didn't list it here. Also I tried adding single quotes around -d and I got:

curl: option -: is unknown curl: try 'curl --help' or 'curl --manual' for more information

Seems like it cannot recognize the - character in the JSON

Answer 1

Pipe the data into curl.exe, instead of trying to escape it.

$data = @{
    fields = @{
        project = @{
            key = "key"
        }
        summary = "summary"
        description = "description - here"
        type = @{
            name = "Task"
        }
    }
}

$data | ConvertTo-Json -Compress | curl.exe -X POST -u username:password -H "Content-Type: application/json" -d "@-"

curl.exe reads stdin if you use @- as your data parameter.

PS: I strongly suggest you use a proper data structure and ConvertTo-Json , as shown, instead of building the JSON string manually.

简单方法（用于简单测试）：

curl -X POST -H "Content-Type: application/json" -d '{ \"field\": \"value\"}'
