我定义了一个自定义查询及其自定义响应，如下所示:
input ILocations {
id: String
address: String
latitude: String
longitude: String
city: String
state: String
}
type IBox {
id: ID
type: String
depth: Float
height: Float
width: Float
}
type ITruck {
id: ID
basePrice: Float
brand: String
model: String
yearModel: Int
axes: Int
hasGPS: Boolean
tons: Float
utilityPercentage: Float
fuelEfficiency: Float
fuelType: FuelType
frontPhoto: String
sidePhoto: String
backPhoto: String
measuresPhoto: String
truckBoxId: ID
truckFreightDriverId: ID
box: IBox
}
type IFreightDriver {
id: ID
state: String
city: String
truck: ITruck
}
type Query {
quotations(
origin: ILocations
destination: ILocations
boxType: String
boxSize: Float
truckTons: Float
): [IFreightDriver]
@function(name: "quotations-${env}")
@auth(rules: [{ allow: public, provider: iam }])
}
如果我在 AppSync 仪表板上执行此查询:
query {
quotations (
origin: {
address: "sdas"
latitude: "sdas"
longitude: "dsa"
city: "Guadalajara",
state: "Jalisco"
},
destination: {
address: "sdas"
latitude: "sdas"
longitude: "dsa"
city: "Zapopan",
state: "Jalisco"
},
boxType: "Seca (cerrada)",
boxSize: 64,
truckTons: 12
) {
id
}
}
我收到有关权限的错误:
{
"data": {
"quotations": [
{
"id": null
}
]
},
"errors": [
{
"path": [
"quotations",
0,
"id"
],
"data": null,
"errorType": "Unauthorized",
"errorInfo": null,
"locations": [
{
"line": 20,
"column": 5,
"sourceName": null
}
],
"message": "Not Authorized to access id on type IFreightDriver"
}
]
}
但是，如果我对 lambda 的响应进行字符串化，并更改查询以接收字符串，如下所示:
quotations(
origin: ILocations
destination: ILocations
boxType: String
boxSize: Float
truckTons: Float
): String
@function(name: "quotations-${env}")
@auth(rules: [{ allow: public, provider: iam }])
我正确收到响应...
{
"data": {
"quotations": "[{\"id\":\"19847d0c-185c-48f6-9e5c-435e3907133a\",\"state\":\"Jalisco\",\"city\":\"Zapopan\",\"truck\":{\"__typename\":\"Truck\",\"model\":\"1234\",\"tons\":12,\"yearModel\":2020,\"measuresPhoto\":\"freight-driver/19847d0c-185c-48f6-9e5c-435e3907133a/trucks/qzo1x9g7kvb51.jpg\",\"truckFreightDriverId\":\"19847d0c-185c-48f6-9e5c-435e3907133a\",\"createdAt\":\"2020-08-13T21:02:36.305Z\",\"brand\":\"chevrolet\",\"fuelEfficiency\":12,\"truckBoxId\":\"b3d9000f-0464-4c3d-b436-f380b19d6fd5\",\"backPhoto\":\"freight-driver/19847d0c-185c-48f6-9e5c-435e3907133a/trucks/QCzn1_mWetzZjAFavJYSaug4F2IMAeOAzJa7T6rhC5Q.jpg\",\"frontPhoto\":\"freight-driver/19847d0c-185c-48f6-9e5c-435e3907133a/trucks/dlb0275xqna51.png\",\"utilityPercentage\":12,\"updatedAt\":\"2020-08-13T21:02:36.305Z\",\"sidePhoto\":\"freight-driver/19847d0c-185c-48f6-9e5c-435e3907133a/trucks/ebcpyk19csa51.jpg\",\"fuelType\":\"premium\",\"hasGPS\":true,\"id\":\"b7ec3b05-78c6-4ed9-823d-172a1e9991e5\",\"axes\":12,\"box\":{\"__typename\":\"Box\",\"width\":4,\"height\":4,\"updatedAt\":\"2020-08-13T21:02:35.840Z\",\"depth\":4,\"createdAt\":\"2020-08-13T21:02:35.840Z\",\"id\":\"b3d9000f-0464-4c3d-b436-f380b19d6fd5\",\"type\":\"Seca (cerrada)\"}},\"basePrice\":null}]"
}
}
为什么要求这些权限？如果有人需要我收到的回复:

更新:我还尝试更改 lambda 响应以仅返回 ids 数组，如下所示:
来自 lambda 的响应:
[ { id: '19847d0c-185c-48f6-9e5c-435e3907133a' }]
来自 AppSync 的错误:

0,

"column": 5,
"sourceName": null
}
],
"message": "Not Authorized to access id on type IFreightDriver"
}
]
}
schema.graphql:
type IFreightDriver {
id: ID
}
type Query {
quotations(
origin: ILocations
destination: ILocations
boxType: String
boxSize: Float
truckTons: Float
): [IFreightDriver]
@function(name: "quotations-${env}")
@auth(rules: [{ allow: public, provider: iam }])
}
最佳答案
您必须提供访问 IFreightDriver 的权限。由于您正在为查询设置 auth，而不是在它正在访问/返回的对象上设置(在您的情况下为 IFreightDriver)，因此它会引发权限错误。但是，当您将查询切换为仅返回字符串时，您不需要为此设置任何权限，这就是您看不到任何错误的原因。当您仅返回 IFreightDriver 的 id 时，情况也是如此。除非您在 IFreightDriver 上设置权限，否则它不会允许您访问 ID。
关于aws-amplify - 无权访问 IFreightDriver 类型上的 id，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/63442276/
