参数验证错误

Question

我使用了0.7.0的Grape gem，并在端点周围有以下验证规则：

params do
    requires :UUID, type: String
    requires :PrimaryJobFunctionCode, type: String
    requires :PrimaryAssetClassCode, type: String
    requires :PrimaryGeographicalFocusCode, type: String
    requires :SecondaryJobFunctionCodes, type: Array
    requires :SecondaryAssetClassCodes, type: Array
    requires :SecondaryGeographicalFocusCodes, type: Array
end
post "save" do

我尝试POST的有效负载是：

  

＆＃34; {       ＆＃34; UUID＆＃34;：＆＃34; SL1-4E6Z6DW＆＃34 ;,       ＆＃34; PrimaryJobFunctionCode＆＃34;：＆＃34; FRUCJF：30＆＃34 ;,       ＆＃34; PrimaryAssetClassCode＆＃34;：＆＃34; FRUCAC：34＆＃34 ;,       ＆＃34; PrimaryGeographicalFocusCode＆＃34;：＆＃34; G：31＆＃34 ;,       ＆＃34; SecondaryJobFunctionCodes＆＃34;：[＆＃34; FRUCJF：69＆＃34]，       ＆＃34; SecondaryAssetClassCodes＆＃34;：[＆＃34; FRUCAC：24＆＃34]，       ＆＃34; SecondaryGeographicalFocusCodes＆＃34;：[＆＃34; G：3D＆＃34;]}＆＃34;

我得到的错误是：

"UUID is missing, PrimaryJobFunctionCode is missing, PrimaryAssetClassCode is missing, PrimaryGeographicalFocusCode is missing, SecondaryJobFunctionCodes is missing, SecondaryAssetClassCodes is missing, SecondaryGeographicalFocusCodes is missing"

我一定错过了一些明显的东西
