Gem HTTParty 如何提交 JSON Array?
class Foo
include HTTParty
end
# Simple post with full url and setting the body
Foo.post('http://foo.com/resources', body: {bar: 'baz'})
怎么 post 这种 Json Array 的参数
[
{"name":"test1","display_name":"test1","numeric":0},
{"name":"test2","display_name":"test2","numeric":0},
{"name":"test3","display_name":"test3","numeric":0}
]
data = [
{"name":"test1","display_name":"test1","numeric":0},
{"name":"test2","display_name":"test2","numeric":0},
{"name":"test3","display_name":"test3","numeric":0}
]
Foo.post('http://foo.com/resources', body: data.to_json, headers: { 'Content-Type' => "application/json" })
这样如何？

歪个楼聊下，我试了一下，如果没有指定顶层参数这种请求，如果是 rails，那么请求自动解析后将 body 的数据放在 "_json" 参数里，我的演示：
curl -d "[{\"a\":1},{\"a\":2}]" -H "Content-Type:application/json" localhost:3000/admin/admin_users
Rails 服务器打印的日志：
Started POST "/admin/admin_users" for 127.0.0.1 at 2017-11-02 00:54:23 +0800
ActiveRecord::SchemaMigration Load (15.8ms) SELECT `schema_migrations`.* FROM `schema_migrations`
Processing by Admin::AdminUsersController#create as */*
Parameters: {"_json"=>[{"a"=>1}, {"a"=>2}], "admin_user"=>{}}
另外我翻了下 rails 源码，找到了 json 解析时候的这个默认行为：
# https://github.com/rails/rails/blob/8c7aa4c7bcb4ae42db8c573ba64a5eabdf54ecd1/actionpack/lib/action_dispatch/http/parameters.rb#L11-L13
DEFAULT_PARSERS = {
Mime[:json].symbol => -> (raw_post) {
data = ActiveSupport::JSON.decode(raw_post)
data.is_a?(Hash) ? data : { _json: data }
}
}
