Question

我有来自<vector>, <string>, <chrono>, <stdio>, <iomanip>, <iostream>, <fstream>, <strsafe>, <math.h>, <thread>, <mutex>, <ctime> Jenkins $ BUILD_URL / api / json的以下输出：

curl

我正在尝试提取启动构建作业的“userId”，因为当前可用的Jenkins插件由于某种原因而无法正常工作。

这是我尝试的但它给了我一个错误：

我认为这与某些“.actions []”块中没有“.causes []”的事实有关，如果是这样的话，是否有可能提取“userId”？

Answer 1

使用jq，您可以使用post-fix“？”来防止不存在运算符，例如在你的情况下：

.actions[].causes[]?.userId? | select(.)

Answer 2

Jenkins拥有自己的api语法，允许您过滤api输出。您可以使用xml版本并指定xpath。在您的情况下，以下网址应该为您提供userId。

curl -g https://ip.us-west-2.compute.amazonaws.com/job/Company-Analytics-Prod-Deploy_New/24/api/xml?xpath=//*/action[1]/cause/userId

Answer 3

如何挖掘和修剪输出：

$ curl -s --insecure -u itaig:password  https://ip.us-west-2.compute.amazonaws.com/job/Company-Analytics-Prod-Deploy_New/24/api/json |
   jq -r '.actions[]' | grep userId | cut -d ":" -f2 | tr -d '"," '

如何使用jq从Jenkins构建URL上的curl中提取userId？
