从web2py以JSON格式返回列表 [英] return a list as JSON from web2py

问题描述

是否可以通过web2py将列表作为JSON列表返回?

Is there any way to return a list as a JSON list from web2py?

当我打到以.json结尾的路线时，web2py会将字典转换为有效的JSON.但是，如果返回值是列表，则其行为异常

when I hit my route ending in .json, web2py converts dictionaries into valid JSON. If the return value is a list however, it behaves unexpectedly

return ["test", "test"]

显示

testtest

和

return [dict(test="test"), dict(test="test")]

完全破坏了它(chrome抱怨ERR_INVALID_CHUNKED_ENCODING).显然，预期行为分别是以下有效的JSON字符串:

breaks it completely (chrome complains with ERR_INVALID_CHUNKED_ENCODING). The expect behaviour is obviously the following valid JSON strings respectively:

["test", "test"]

和

[{"test":"test"}, {"test":"test"}]

推荐答案

在@service.json装饰器中注册json服务，并使用`app/controller/call/json/method'调用它，这给了我预期的行为:

registering a json service with the @service.json decorator and calling it with `app/controller/call/json/method' gave me the behaviour I expected:

def f():
    return ["test1", "test2"]

def call():
    return service()

响应正文是

["test1", "test2"]

内容类型设置为json

with content-type set to json
