IBM Watson Concept Insights概念搜索使用Curl传递多个/一组id作为参数

Question

所以，我试图在IBM Concept Insights上使用Curl在查询上传递多个id（“Array of concept”）。根据本网站上的文档，我应该能够做到，但我无法弄清楚如何使它工作 - ＆gt; http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/concept-insights/api/v2/?curl#conceptual_search

如果我使用链接上产生的“示例请求”并将其修改为至少在同一个get data命令上添加另一个查询，这就是我认为它会起作用的方式。

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，我得不到任何结果。甚至不是错误。

有什么想法吗？

请不要指出显而易见的......当然，我正在用我的凭据替换“{username}”：“{password}”。 ：）

Answer 1

而不是-d "ids=..."，您应该使用--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"

Answer 2

在您的示例中，ids在 POST 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

尝试下面的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，以便进行以下概念：

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

使用http://meyerweb.com/eric/tools/dencoder/

等在线网址编码器

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

最后使用ids=<encoded array>作为网址的一部分。
