Windows 7 R 版本 3.4.0 httr -- 连接到人口普查地理编码器时出现 404 错误 api

Question

我运行以下代码是为了通过人口普查地理编码器 api 发送批处理文件。我看了 and the Documentation for the API。这对我没有帮助。我希望得到一些包含地址信息的数据 return... 而不是 404 错误。我似乎在 return 调用中遇到错误，我似乎可以正常发送数据，但无法检索数据？请帮我弄清楚为什么会出现错误。谢谢！

require(httr)

req <- POST("http://geocoding.geo.census.gov/geocoder/geographies/addressbatch", 
        body = list(
          addressFile = upload_file("addresses.csv"),
          benchmark = "Public_AR_Census2010",
          vintage = "Census2010_Census2010"
        ), 
        encode = "multipart",
        verbose())
stop_for_status(req)
content(req)

我得到以下输出

实际上，如果您从 http 更改为 https，您的代码将起作用。
