您的
ParseResponse函数存在问题，您正在调用
json.Unmarshal作为第一个参数传递
json，这是一个包名：这是模棱两可的。
如您所见，代码可以很好地更改
ParseResponse函数。
package mainimport ( "encoding/json" "fmt")type gateway struct { Characteristics []string `json:"characteristics"` CreatedAt string `json:"created_at"` Credentials[]interface{} `json:"credentials"` Descriptioninterface{} `json:"description"` GatewaySpecificFields []interface{} `json:"gateway_specific_fields"` GatewayTypestring `json:"gateway_type"` Name string `json:"name"` PaymentMethods []string `json:"payment_methods"` Redacted bool `json:"redacted"` State string `json:"state"` Token string `json:"token"` UpdatedAt string `json:"updated_at"`}type gateways struct { Gateways []gateway `json:"gateways"`}func ParseResponse(js []byte) { var parsed gateways json.Unmarshal(js, &parsed) fmt.Println(parsed)}func main() { var js []byte = []byte(`{"gateways": [ { "token": "my_token_here", "gateway_type": "test", "description": null, "payment_methods": [ "credit_card", "sprel", "third_party_token", "bank_account", "apple_pay" ], "state": "retained", "created_at": "2016-03-12T18:52:37Z", "updated_at": "2016-03-12T18:52:37Z", "name": "Spreedly Test", "characteristics": [ "purchase", "authorize", "capture", "credit", "general_credit", "void", "verify", "reference_purchase", "purchase_via_preauthorization", "offsite_purchase", "offsite_authorize", "3dsecure_purchase", "3dsecure_authorize", "store", "remove", "disburse", "reference_authorization" ], "credentials": [], "gateway_specific_fields": [], "redacted": false }]}`) ParseResponse(js)}输出：
