因此，我试图在 IBM Concept Insights 上使用 Curl 在查询中传递多个 id（“概念数组”）。根据该站点上的文档，我应该能够做到，但我无法弄清楚如何使其工作-> http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/concept-见解/api/v2/?curl#conceptual_search

如果我使用链接上提供的“示例请求”并将其修改为至少在同一个获取数据命令上添加另一个查询，我认为这就是它的工作方式。

curl -u "{username}":"{password}" -G -d "ids=[\"/graphs/wikipedia/en-20120601/concepts/Artificial_intelligence\", \"/graphs/wikipedia/en-20120601/concepts/HTML\"]" "https://gateway.watsonplatform.net/concept-insights/api/v2/corpora/public/ibmresearcher/conceptual_search"

当我输入该命令时，我没有得到任何结果。甚至没有错误。

有什么想法吗？

请不要指出明显的......当然，我用我的凭据替换“{username}”：“{password}”。:)

而不是-d "ids=..."你应该使用--data-urlencode "ids=..."

这应该有效：

curl -u "%ci-username%":"%ci-password%" -G --data-urlencode "ids=[\"/graphs/wikipedia/en-20120601/concepts/Artificial_intelligence\", \"/graphs/wikipedia/en-20120601/concepts/HTML\"]" "https://gateway.watsonplatform.net/concept-insights/api/v2/corpora/public/ibmresearcher/conceptual_search"

在您的示例中，在POSTids请求中作为正文的一部分发送，但 API 期望它在查询中并且请求为GET。

试试下面的 curl 命令：

curl  -u "{username}":"{password}" "https://gateway.watsonplatform.net/concept-insights/api/v2/corpora/public/ibmresearcher/conceptual_search?ids=%5B%22%2Fgraphs%2Fwikipedia%2Fen-20120601%2Fconcepts%2FArtificial_intelligence%22%2C%20%22%2Fgraphs%2Fwikipedia%2Fen-20120601%2Fconcepts%HTML%22%5D&cursor=0&limit=10"

它将使用人工智能和HTML两个概念进行概念搜索。

输出：

您需要对 json 数组进行 url 编码，因此对于以下概念：

["/graphs/wikipedia/en-20120601/concepts/Artificial_intelligence", "/graphs/wikipedia/en-20120601/concepts/Machine_learning"]

使用在线 URL 编码器，例如http://meyerweb.com/eric/tools/dencoder/

%5B%22%2Fgraphs%2Fwikipedia%2Fen-20120601%2Fconcepts%2FArtificial_intelligence%22%2C%20%22%2Fgraphs%2Fwikipedia%2Fen-20120601%2Fconcepts%HTML%22%5D

最后ids=<encoded array>用作 URL 的一部分。
