当 curl 时，HTTParty 补丁请求不起作用

Question

在Rails 4.2中，我正在使用HTTParty为SendGrid的API版本3制作API包装器。这是它的样子：

class SendGridV3
include HTTParty
debug_output $stdout
base_uri 'https://api.sendgrid.com/v3'
format :json
headers 'Authorization' => "Bearer #{ENV['SENDGRID_API_KEY']}"
def self.enforce_tls
response = patch '/user/settings/enforced_tls', query: {require_tls: true}.to_json
puts response
response['require_tls']
end
end

当我运行SendGridV3.enforce_tls时，预期的响应是{"require_tls": true, "require_valid_cert": false}但实际响应是{"require_tls": false, "require_valid_cert": false}

这是debug_output的输出

Conn close
{"require_tls"=>false, "require_valid_cert"=>false}

我还尝试使用body:而不是query:传入 JSON

当我使用此卷曲时，我得到了预期的响应：

curl -X "PATCH" "https://api.sendgrid.com/v3/user/settings/enforced_tls" -H "Authorization: Bearer MY-SENDGRID-KEY" -H "Content-Type: application/json" -d '{"require_tls":true}'

那么，当HTTParty失败时，curl是如何做到这一点的呢？

Answer 1

显式设置Content-Type以及使用:body将使其工作。

class SendGridV3
...
headers 'Content-Type' => 'application/json'
def self.enforce_tls
response = patch '/user/settings/enforced_tls', body: {require_tls: true}.to_json
puts response
response['require_tls']
end
end

归咎于 OP，以指出在此用例中需要:body:query。

Answer 2

我认为查询中的.to_json导致了问题，HTTParty 对query参数采用 rubyhash，它解析该参数以创建查询字符串。.to_json会导致query参数成为字符串，因此按原样传递查询以构造 URI。从那里删除.to_json应该可以解决问题。
