我在尝试将推文写入我的 psql 数据库时遇到错误。
我已经在互联网上搜索了高低(可能还不够好)以寻找答案,但无济于事。我在这里查看了答案 - 但建议是将字符串转换为 UTF8(即使响应标头声称它已经是 UTF-8)。
我用这段代码做到了:
# get the data from twitter
response = RestClient.get "http://search.twitter.com/search.json?rpp=100&since_id=238726971826253824&q=love"
# find the data encoding using CharDet
data = CharDet.detect(response.body)
encoding = data['encoding']
# create a new instance of Iconv with UTF-8 and then convert response.body
ic = Iconv.new('UTF-8//IGNORE', encoding)
converted_response = ic.iconv(response.body + ' ')[0..-2]
# take the data and convert it to JSON
response_json = ActiveSupport::JSON.decode(converted_response)
然后我们解析 response_json 并在数据库内部创建推文。但是,这样做时,我们会在下面收到此错误。

我已经继续测试了 response_json 的类(返回 Hash),即使在该错误结束时它显示 HashWithIndifferentAccess。
其他人有类似的问题并知道解决方案吗?
谢谢!
