Create a Pull request using curl with a for loop in bash

Edited

How would I go to create a PR using curl but referring to a for loop so it would loop through multiple repos, declared in a variable.

 

#!/bin/bash
## declare an array variable
declare -a LIST=("repo1" "repo2")

## now loop through the above array
for i in "${REPOS[@]}"
do
   echo "$i"
   # or do whatever with individual element of the array

#      -u myuser:password \
#      --request POST \
#      --header 'Content-Type: application/json' \
#        --data '{
#            "title": "My_PR_Created",
#            "source": {  
#                "branch": {
#                  "name": "BranchForTest"
#         }
#     }
#  }'
done
Outcome: it runs but doesn't create the PR's

Hey @cesar ramirez ,

Welcome to Atlassian Community!

 

I did some tests in my own repositories, and was able to get the bash script working by using the following code : 

#!/bin/bash

 
REPOS=("repo_1" "repo_2")

 
# Loop the array of repos

for i in "${REPOS[@]}"

do

   printf "\n\n Attempting to create PR for repository:  $i \n\n"
 

  curl -v https://api.bitbucket.org/2.0/repositories/<workspace>/"$i"/pullrequests/ \

      -u bitbucket_username:app_password \

      --request POST \

      --header 'Content-Type: application/json' \

      --data '{

            "title": "My_PR_Created",

            "source": {

                "branch": {

                  "name": "name_of_source_branch"

         }

     }

  }'

done

I've added the verbose flag ( -v ) in the curl command so it prints out more information about the request, such as the status code and the response from the API, and you can use it to analyze if the request was successful or not, and if not, have more details about the failure reason such as authentication issue, or missing data in the body of the request.

Also note that you need to use your bitbucket username(not the e-mail address), which you can find in your account's personal settings, along with an App Password (not your account password)  as the credentials for authentication.

Could you please try using the above and let us know how it goes? 

Thank you, @cesar ramirez .

Kind regards,

Patrik S

Thank you Patrick, I am in the process of testing it. I really appreciate your response.

How would you merge those PR?, I have these, but I get a syntax error.

 

 

#!/bin/bash

#Loop Works with array, but once we introuduce the API it doesn't

## declare an array variable
declare -a REPOS=("name")

## now loop through the above array
for i in "${REPOS[@]}"
do
   echo "$i"
   # or do whatever with individual element of the array

  curl -v https://api.bitbucket.org/2.0/repositories/{name}/"$i"/pullrequests/{id_number}/merge' \
     -u my username:token \
     --request POST \
     --header 'Content-Type: application/json' \
        --data '{
            "type": "<string>",
            "message": "<string>",
                "close_source_branch": true,
                  "merge_strategy": "merge_commit"
         }'

Hey @cesar ramirez ,

Could you share what is the specific error your script is returning? 

Also, the Bitbucket API endpoint used to merge a pull request requires you to pass the pull request ID number as part of the URL, as documented here. Checking in the code you have shared, I don't see any variables being populated with the pull request ID number, and this is likely the reason why the API call is failing.

If you want to merge all the open pull requests in a repository programmatically, you would need to first get the PR IDs by calling the List Pull Request endpoint, and then use the list of PR IDs returned to then call the Merge Pull Request endpoint for each PR ID. 

Thank you, @cesar ramirez .

Kind regards,

Patrik S
