将标头添加到 PostHttp 处理器或 Apache Nifi [英] Add header to PostHttp processsor Apache Nifi

问题描述

我试图在我的 apache nifi 中的 post 请求标头中添加一个自定义标头，我已经看到在配置选项卡中有要作为 http 标头发送的属性(正则表达式)我对正则表达式不是很熟悉，不知道如何添加标题及其值，如下所示:token : READ ?

Im trying to add a custom header in my post request header in apache nifi, I have seen that in the configuration tab there's Attributes to send as http header (regex) I'm not very familiar with regex, any idea how to add a header and its value like the following : token : READ ?

推荐答案

PostHttp 的作为 HTTP 标头发送的属性(正则表达式)"属性可以接受正则表达式，但它可以很好地指定单个属性名称，例如令牌.如果您有多个要命名的属性，则可以使用管道将它们或"在一起:

PostHttp's "Attributes to Send as HTTP Headers (Regex)" property can accept a regex, but it will work just fine to specify a single attribute name like token. If you had multiple attribute you wanted to name, you could use a pipe to "or" them together:

token|attrib2|attrib3

对于您选择的每个属性，属性名称和值将作为 HTTP 标头名称和值发送.

For each attribute you selected, the attribute name and value are sent as the HTTP header name and value.
