我正在尝试向Jenkins API提交POST以创建新作业。我按照API文档使用Postman来提出具体请求。
当我发出请求时，服务器返回ERROR 500并出现以下错误：

我看了一下我的config.xml文件，文件顶部没有空格。除此之外，我不确定它在说什么。我用Google搜索并查看了SO但没有发现任何与在CLI之外使用此API有关的内容。任何人都有成功的经验或指点吗？
这是我对API发布的帖子请求：
POST /createItem?name=Tes234t6.dev HTTP/1.1
Host: XXX.XXX.XXX.XXX:8080
Content-Type: text/xml

尽管Jenkins API说要发布“config.xml”，但你实际上并没有发送文件，而是发布了xml数据。
我这样做的方法是使用Postman插件进行chrome，并将config.xml文件的内容直接添加到RAW输入。这对我有用。
希望这能让其他人感到沮丧。

我也偶然发现了这个问题但你的解决方案对我们没有用。所以，如果有人谷歌搜索这个问题，这是另一种可能的解决方案。
我们的 Jenkins （通过AJP连接）前面有一个 Apache 。使用Jeknins版本1.534（或以下）时，一切正常。升级到1.535或更高版本后，我们在尝试通过REST-API创建作业时遇到上述错误。这并不是一直发生的，而是20个工作岗位中的一个。
事实证明，这只发生在通过Apache调用REST-API（然后使用ajp转发给Jeknins）时。解决方案是直接对Jenkins进行REST调用。
