我正在嘗試使用 Python requests 模塊從 GraphDB REST API 運行 DELETE 查詢，但沒有運氣。
SELECT 查詢requests.get()作業正常：
query = "http://localhost:7200/repositories/myreponame?name=&infer=true&sameAs=false&query=SELECT ?s ?p ?o
WHERE {
?s ?p ?o .
}
"
response = requests.get(query, headers = {"Authorization" : token})
但每當我切換到 DELETE 查詢時，它就不起作用了。
如果我使用 DELETE 查詢，則會requests.get()收到此錯誤：
query = "http://localhost:7200/repositories/myreponame?name=&infer=true&sameAs=false&query=DELETE {
?s ?p ?o .
}
WHERE {
?s ?p ?o .
}
"
MALFORMED QUERY: Encountered " "delete" "DELETE "" at line 1, column 1.
Was expecting one of:
"base" ...
"prefix" ...
"select" ...
"construct" ...
"describe" ...
"ask" ...
如果我改用 DELETE 查詢requests.delete()，我會得到：
Repository delete error: query supplied with request
我究竟做錯了什么？
我正在以管理員權限訪問 API，所以這不是問題。
編輯： 根據 UninformedUser 的評論，我嘗試切換到 POST 請求，并將 URL 從query修改為update。還添加了此處所述的適當內容型別：
query = "http://localhost:7200/repositories/myreponame?name=&infer=true&sameAs=false&update=DELETE {
?s ?p ?o .
}
WHERE {
?s ?p ?o .
}
"
response = requests.post(query, headers = {"Authorization" : token, "Content-Type": "application/x-www-form-urlencoded"})
現在收到以下錯誤：
Missing parameter: query
uj5u.com熱心網友回復：
原來我錯過了 GraphDB 的一個特定要求：對于更新，必須/statements在存盤庫 ID 之后附加：
query = "http://localhost:7200/repositories/myreponame/statements?name=&infer=true&sameAs=false&update=DELETE {
?s ?p ?o .
}
WHERE {
?s ?p ?o .
}
"
response = requests.post(query, headers = {"Authorization" : token, "Content-Type": "application/x-www-form-urlencoded"})
