利用BitBucket API 获取 [commit/branc

Bitbucket 给我们提供了很多API， 我们可以利用它来做一些自动化的工作， 比如commit就有这些API:
https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositories/%7Busername%7D/%7Brepo_slug%7D/commit

1. 获取两个commit的diff：
   API :GET https://api.bitbucket.org/2.0/repositories/{username}/{repo_slug}/diff/{spec}

• {username} 就是username, 此次repo所属的用户（私有库）
• {repo_slug} 就是打开bitbucket库后，显示在URL里的库名
• {spec} 就是commit, 可以是2个commit， 这样写A..B， 也可以是一个commit， 这样写A， 一个commit对比的对象是A 的parent commit。
  举例:

curl  -u yourbitbucketemail@xx.com:yourpassword https://api.bitbucket.org/2.0/repositories/lt-dev/report-center/diff/d3178a2

curl  -u yourbitbucketemail@xx.com:yourpassword https://api.bitbucket.org/2.0/repositories/lt-dev/report-center/diff/d3178a2..5b5fda5

2. 获取一个branch的所有commit:
   https://api.bitbucket.org/2.0/repositories/{username}/{repo_slug}/commits?until={branch}
   举例：

curl  -u yourbitbucketemail@xx.com:yourpassword https://api.bitbucket.org/2.0/repositories/lt-dev/db-update/commits?until=test1&limit=0&start=0

3. 获取一个pull request 的diff:
   https://api.bitbucket.org/2.0/repositories/{username}/{repo_slug}/pullrequests/{pullrequestID}/diff
   举例：

curl  -u yourbitbucketemail@xx.com:yourpassword https://api.bitbucket.org/2.0/repositories/lt-dev/backend/pullrequests/7272/diff

4. 发起一个pull request, 记得带上content-type.

curl https://api.bitbucket.org/2.0/repositories/lt-dev/db-update/pullrequests   
-u yourbitbucketemail@xx.com:yourpassword  
--request POST   
--header 'Content-Type: application/json'     
--data '{
    "title": "API TEST",
    "source": {
        "branch": {
            "name": "test1"
        }
    },
    "destination": {
        "branch": {
            "name": "test2"
        }
    }
}'

得到的结果跟你运行git log是一样的，可以用正则表达式做进一步的信息提取工作。
比如我用golang, 提取本次diff改动到的文件：

resBody:={diffcontent}
regex := regexp.MustCompile(`diff --git a(.+) b/`)
allDiffs := regex.FindAllStringSubmatch(resBody, -1) 
for _, difs := range allDiffs {
    for index, dfs := range difs {
        if index > 0 {
            diffFiles = append(diffFiles, dfs)
        }
    }
}
sort.Strings(diffFiles)
return diffFiles

记录个暂时没找到答案的问题：
当用Bitbucket API 做2个branch的Diff的时候(逆向Diff)，发现有个文件。但在Bitbucket页面做用同样的branch做pull request的时候却没有Diff？？
