你可以添加一個樣本JSON文件，好嗎？我很難想象你想要做什麼。 –

@ KenY-N以下是json文件的內容.... { 「A」：[[150,450]，[150,150]，[250,150]，[250,450]，[250,275]，[150,275]]，「C」：[[232,552]，[232,551]，[[140,543]，[ [231551]，[230550]，[223549]，[217547]，[210546]，[202545]，[187544]，[175544]，[162544]，[147547]，[122556]，[114562]，[111566 ]，[103576]，[95589]，[89606]，[86654]，[93670]，[105686]，[126705]，[144713]，[165717]，[189718]，[221711]，[234705]， [243,700]] } – user3281879

它給我NULL – user3281879

它在哪裏給你NULL？你是否傳遞了一封適當的信？ – Catherine

它不需要任何字母，只是簡單地返回空....是的，我通過「C」！ – user3281879
