json对象应该以{开头，以}结尾。您应该具有：

{
    "customer": {
        "gender": 1,
        "company": "MyCompany",
        "name": "Doe",
        "firstname": "John",
        "phone": "0606060606",
        "address": { 
            "address": "123 main street",
            "address2": "456 second street",
            "postalCode": 17101,
            "city": "Anytown",
            "country": "UK" 
            },
            "references": [ 123458, 154568 ] 
     }
 }
