【问题描述】:
当尝试使用 Faraday gem POST 多部分数据(文件和 json)时,远程服务器无法识别 json 数据参数并且由于它是必需参数而失败并出现验证错误。
connection = Faraday.new(url: "#{uri.scheme}://#{uri.host}:#{uri.port}") do |faraday|
faraday.request :multipart
faraday.request :url_encoded
faraday.adapter :net_http
end
request_data = { file: Faraday::UploadIO.new('somefile.png', 'image/png'), jsonBody: JSON.dump({ id: 'foo', name: 'bar' }) }
response = connection.post(uri.request_uri) do |request|
request = Ff::Api::RequestHeaders.set(request, self.api_options)
request.headers['content-type'] = 'multipart/form-data; boundary=-----------RubyMultipartPost'
request.body = request_data
end
工作 CURL 请求:
curl -v -H 'Authorization: bearer 7d70fb31-0eb9-4846-9ea8-933dfb69d8f1' \
-H 'Accept: application/xml,application/xhtml+xml,application/json,text/html,text/plain' \
-H 'Content-Type: multipart/form-data' \
-F 'jsonBody={"id":"foo","name":"bar"};type=application/json' \
'http://localhost:8080/localproject/rest-resource/items'

请求正文的附加前缀“type=application/json”似乎与 CURL 有所不同。没有找到任何方法对法拉第做同样的事情。
法拉第版本:0.12.2 & 0.14.0
Ruby 版本:2.3.3
导轨:5.2
任何帮助将不胜感激。
【问题讨论】:
-
您是否尝试过来自终端的 CURL 请求有效?尝试将法拉第请求的日志与 CURL 进行比较。如果您在问题中发布日志可能会有所帮助。
