無法在r中使用httr包復制Python request.post
[英]Trouble replicating a Python requests.post with the httr package in r
問題描述
這在Python中使用請求庫工作：
plist5 = ["5021072"]
data = {"startDate": "2014-04-01", "endDate": "2014-04-01", "pnodeList": plist5}
data = json.dumps(data)
url = 'https://dataminer.pjm.com/dataminer/rest/public/api/markets/realtime/lmp/daily'
headers = {'Content-Type': 'application/json'}
response = requests.post(url, data=data, headers=headers)
我想使用httr包在R中復制相同的內容。 這是我嘗試失敗的嘗試：
url <- 'https://dataminer.pjm.com/dataminer/rest/public/api/markets/realtime/lmp/daily'
response <- POST(url, body = list(pnodeList = "5021072",
startDate = "2014-04-01",
endDate = "2014-04-01"),
headers = list('Content-Type' = 'application/json')
)
這是我從R代碼得到的響應：
Response [https://dataminer.pjm.com/dataminerui/]
Date: 2016-02-24 15:28
Status: 200
Content-Type: text/html
Size: 159 B
<!-- Plain HTML page that kicks us into the app -->
<html>
<head>
<meta http-equiv="Refresh" content="0; URL=pages/public/index.html">
</head>
</html>
> content(response)
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<!-- Plain HTML page that kicks us into the app --><html><head><meta http-equiv="Refresh" content="0; URL=pages/public/index.html"></head></html>
非常感謝任何有關如何進行的指導。

希望有人可以詳細說明以下各項為何起作用，和/或如何區分“錯誤”版本中發送的內容與該“正確”版本中發送的內容：
response <- POST(url, body = list(pnodeList = list("5021072"),
startDate = "2014-04-01",
endDate = "2014-04-01"),
encode = "json")
)
這本《快速入門指南》促使我嘗試以上操作。
添加verbose()允許您查看發送的內容：
POST(url, body = list(pnodeList = list("5021072"),
startDate = "2014-04-01",
endDate = "2014-04-01"),
encode = "json",
verbose()
)
最初嘗試時最明顯的缺陷是在python版本中， pnodeList是list 。
