如何在 Mule 3 中拆分函数后删除 %20（URI 编码 space）

Question

我正在使用 split 函数根据结果创建一个数组，因此我可以使用 foreach 循环。 foreach 循环包含 HTTP 请求连接器，它将数组作为有效负载并循环遍历不同的 ID。问题是当数组进入循环时它显示 space 符号 (%20)，这使得请求错误。没有 space 标志一切正常。所以我的问题是如何删除 http 请求中的 spaces？下面我添加了输入和输出

拆分前

5598f15c-e4fb-482f-ba41-0ced971ec737,f6cb0890-3650-47c0-ba53-202229c8c5df,0de65b3b-b2c0-4dba-a54a-2bbef4e3bcf2

在上面的 Id 上拆分

#[java.util.Arrays.asList(flowVars.Id.split(','))]

和 Mime 类型 application/java。在 split() 之后，它创建了一种 java.lang.String

0 = 5598f15c-e4fb-482f-ba41-0ced971ec737
1 = f6cb0890-3650-47c0-ba53-202229c8c5df
2 = 0de65b3b-b2c0-4dba-a54a-2bbef4e3bcf2

我在 HTTP 请求连接器中使用下一个作为基本路径（我滥用了基本路径，所以我可以动态添加内容或负载；）

/request/change/odata/serviceRequest?$filter=id eq#[payload]

进入循环时我看到这个 URL

https://service.request.com/request/change/serviceRequest?$filter=id%20eq5598f15c-e4fb-482f-ba41-0ced971ec737/%20

预期的结果需要这样；

https://service.request.com/request/change/serviceRequest?$filter=id eq 5598f15c-e4fb-482f-ba41-0ced971ec737

Answer 1

这真是在滥用基本路径。它不打算以这种方式使用。滥用 basePath 生成的 URL 与预期不同。将空格编码为“%020”是一个标准，应该不会导致任何问题。

尝试改为设置查询参数并在每次迭代中更改其值。类似于：

        <http:request config-ref="HTTP_Request_Configuration" path="/somepath" method="{METHOD}" doc:name="HTTP {METHOD}">
            <http:request-builder>
                <http:query-params expression="#[flowVars.params]"/>
            </http:request-builder>
        </http:request>

并使表达式成为整个字符串，而不仅仅是 id，将 flowVars.params 设置为类似以下内容：{"$filter": "id eq #[payload]"}
