我已经制作了api，现在我想在我的webapp中使用该api。当我在postman中检查api的输出时，结果只是json：
邮递员的结果：
"{"result":{"message":"Success","school":[{"SchoolName":"Lehner-Hackett","Company":"Dare, Bailey and Bednar","Address":"33972 Mills LockDuBuqueshire, FL 74380","Zip":"52192-","City":"Kubshirecvd","PhoneNumber":"572-489-9606435"},{"SchoolName":"O'Conner PLC","Company":"Dare, Bailey and Bednar","Address":"46849 Tara Plaza\nNew Berenicemouth, NV 36571","Zip":"24669","City":"North Francesview","PhoneNumber":"1-373-907-1357"},{"SchoolName":"Botsford-Huels","Company":"Dare, Bailey and Bednar","Address":"668 Georgiana Lights\nPort Payton, PA 90419-1623","Zip":"56373","City":"Nashville","PhoneNumber":"1-255-355-1138"}]}}"
在我的api中，我像这样返回json：
return $output = [
'SchoolName' => $school->SchoolName,
'Company' => $school->company->CompanyName,
'Address' => $school->Address,
'Zip' => $school->Zip,
'City' => $school->City,
'PhoneNumber' => $school->PhoneNumber
];
如果我在webapp中得到结果，结果就是：

为什么我的网络应用程序会收到其他内容？
