如何使 gem WebMock 与包含 [方括号] 的 json 一起工作？
How do I make the gem WebMock work with json that includes [square brackets]?
有问题的 Rails 应用在测试中使用 Rspec、Capybara 和 WebMock。
在一个测试场景中，此代码有效：
response = RestClient.post 'the.domain.com',
{
"dados": {
"head": {
"servico": "autenticacao",
"chave": ""
},
"data": {
"empresa": "my_name",
"login": "my_login",
"senha": "my_password"
}
}
}.to_json
RSpec.configure do |config|
config.before(:each) do
stub_request(:any, 'the.domain.com').
with( body: hash_including(
{"dados": {
"head": {
"servico": "autenticacao",
"chave": ""
},
"data": {
"empresa": "my_name",
"login": "my_login",
"senha": "my_paasword"
}
}}.to_json
) ).to_return(
status: 200,
body: {"dados": {"btms": {"chave": "returned_key"}}}.to_json,
headers: {}
)
end
end
但是在同一场景中，紧接着发生的这件事不会：
data = []
data << {
"cdg_tipo_transporte": "3"
}
response = RestClient.post 'the.domain.com',
{
"dados": {
"head": {
"servico": "reserva_salva_lote",
"chave": response["dados"]["btms"]["chave"]
},
"data": data
}
}.to_json
RSpec.configure do |config|
config.before(:each) do
data = []
data << {
"cdg_tipo_transporte": "3"
}
stub_request(:any, 'the.domain.com').
with( body: hash_including(
{"dados": {
"head": {
"servico": "reserva_salva_lote",
"chave": "returned_key"
},
"data": data
} }.to_json
) ).to_return(
status: 200,
body: {"Status?": "OK"}.to_json,
headers: {}
)
end
end
我得到的错误是关于如何禁用真正的 HTTP 连接，这是一个未注册的请求。我认为这意味着 Rails and/or WebMock 与 json 不匹配。
我调查了不同的事情并尝试了不同的事情。似乎方括号是问题所在。当我在没有它们的情况下构建几乎任何东西时，它都有效。当我把它们放回去时，代码又坏了。
在这种情况下如何使用方括号？我需要它们在那里，因为我要发布到的真实 API 需要这种格式。
顺便说一句，开发环境与实际 API 通信，代码工作正常。人体试验是完美的。只是自动测试一直失败！
更新
这是错误堆栈：
保存响应的变量说 <WebMock::NetConnectNotAllowedError: Real HTTP connections are disabled. Unregistered request: 然后显示请求、建议的存根（与我的相匹配）和已注册的存根。
在此之下，我得到：

hash_including 采用键名和键值对进行匹配，您将 {...}.to_json 传递给它，因此它将尝试匹配整个 json 值作为键。
您的第二个请求存根期望 dados.head.chave 等于 "1234abcd"，但第一个存根 returns "returned_key" 在 response["dados"]["btms"]["chave"] 中，显然存根不匹配导致 WebMock::NetConnectNotAllowedError.
