我正在使用带有 Python 的 Google Endpoints Framework ( https://cloud.google.com/endpoints/docs/frameworks/python/get-started-frameworks-python ),并且一直在使用它构建 REST API。
我能够在响应中返回 JSON 对象(字典),例如:
{
"items":[
{
"id": "brand_1_id",
"name": "Brand 1"
},
{
"id": "brand_2_id",
"name": "Brand 2"
}
]
}
但是,我无法返回 JSON 数组(列表)作为响应,例如:
[ {“id”:“brand_1_id”,“名称”:“品牌 1”},{“id”:“brand_2_id”,“名称”:“品牌 2”}]
以下是我用来返回响应的代码片段
以下是为发送响应而创建的类:
class BrandResponse(messages.Message):
id=messages.StringField(1, required=True)
brandName = messages.StringField(2, required=True)
brandEmail=messages.StringField(3, required=True)
brandPhone=messages.StringField(4,required=True)
brandAddress=messages.StringField(5,required=True)
brandCity=messages.StringField(6,required=True)
brandState=messages.StringField(7,required=True)
brandCountry=messages.StringField(8,required=True)
brandPostalCode=messages.StringField(9,required=True)
class MultipleBrandResponse(messages.Message):
items=messages.MessageField(BrandResponse,1,repeated=True)
以下是处理请求的方法:
@endpoints.method(
MULTIPLE_BRAND_PAGINATED_CONTAINER,
MultipleBrandResponse,
path='brand',
http_method='GET',
name='Get Brands',
audiences=firebaseAudience
)
def getBrands(self,request):
brandResponse=[]
query = BrandDB.query()
brands = query.fetch(request.limit, offset=request.start)
for brand in brands:
brandResponse.append(BrandResponse(
id=brand.key.urlsafe(),
brandName=brand.name,
brandAddress=brand.address,
brandCity=brand.city,
brandState=brand.state,
brandCountry=brand.country,
brandPostalCode=brand.postalCode,
brandPhone=brand.phone,
brandEmail=brand.email))
print("Brand count: "+str(brandResponse.count))
if len(brandResponse) == 0:
raise endpoints.NotFoundException("No brands")
return MultipleBrandResponse(items=brandResponse)
知道如何直接返回 JSON 数组,而不是包装在 JSON 对象内的键中。
