IBM Watson Concept Insights 概念搜索使用 Curl 传递多个/一个 id 数组作为参数

Question

因此，我正在尝试使用 IBM Concept Insights 上的 Curl 在查询中传递多个 id（“概念数组”）。根据这个网站上的文档，我应该可以做到，但我不知道如何使它工作-> http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercloud/concept-insights/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 get data 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，我没有返回任何结果。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}”。 :)

Answer 1

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

这应该可行：

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。

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

最后使用ids=<encoded array> 作为 URL 的一部分。
