我在哪里在Bluemix中指定AlchemyAPI密钥？ [英] Where do I specify the AlchemyAPI key in Bluemix?

问题描述

我已经将AlchemyAPI服务添加到了Bluemix上的Python应用程序中。我可以在AlchemyAPI服务的服务凭证中看到API密钥。我应该在哪里在应用程序代码或文件中指定此密钥，以便可以调用该服务？该代码运行良好，除了我称之为AlchemyAPI的那一部分外，其他所有功能均正常运行。

I've added the AlchemyAPI service to my Python app on Bluemix. I can see the API key in the service credentials of the AlchemyAPI service. Where, in the app code or files should I specify this key so that I can call the service? The code runs fine and does everything except the part where I call AlchemyAPI.

我遵循了在此处入门教程，但仅以获取密钥停止，没有告诉我如何

I followed the Getting started tutorial here, but it just stops with "Get the key" and doesn't tell me what to do with it.

我尝试过但没有用的一些东西：

Some things that I tried but which did not work:

• 像这样在 manifest.yml 文件中添加了一个条目。没用。

• Added an entry to the manifest.yml file, like this. Did not work.

services:
- the_alchemy-service_name
applications:
- path: .
  env:
     ALCHEMY_KEY: the_actual_key

• 在应用程序代码中，称为密钥在调用AlchemyAPI之前。没用。



VCAP_SERVICES = os.getenv('VCAP_SERVICES')
key = (VCAP_SERVICES['alchemy_api'][0]['credentials']['apikey'])
from alchemyapi import AlchemyAPI    
alchemyapi = AlchemyAPI()




推荐答案

通过@Frederic和@German共享的资源，我可以通过更多的研究找到答案。我没有按原样使用建议的SDK，因为这些SDK包含一切，并且我试图创建一个简单演示应用程序。

Thanks to the resources shared by both @Frederic and @German, I was able to find the answer with a bit more research. I did not use the suggested SDKs as-is because the SDKs contain everything and I am trying to create a simple demo app.

请勿调用AlchemyAPI模块。而是调用Watson Developer Cloud模块。

Do not call the AlchemyAPI module. Call the Watson Developer Cloud module instead.

对于Bluemix上的Python应用程序，依赖项必须列在requirements.txt文件中。 Bluemix将自动pip安装这些模块，而无需您执行任何操作。

For a Python app on Bluemix, the dependencies must be listed in a requirements.txt file. Bluemix will automatically pip install these modules, without you having to do anything.

因为我使用的是AlchemyAPI服务（并通过了他们的入门指南），所以我列出了AlchemyAPI作为 requirements.txt 中的依赖项。我以为Bluemix会点安装它。在我的Python代码中，我是通过从alchemyapi import AlchemyAPI 调用该模块的。

Because I was using the AlchemyAPI service (and went by their Getting Started guide), I listed AlchemyAPI as a dependency in requirements.txt. I assumed Bluemix would pip install it. In my Python code, I called that module by from alchemyapi import AlchemyAPI.

错误的假设。不能通过Bluemix点安装 alchemyapi 。调用的模块是 watson-developer-cloud 。

Wrong assumption. alchemyapi cannot be pip installed via Bluemix. The module to call is watson-developer-cloud.

一旦被调用，您可以指定api密钥，这样：

Once that's called, you can specify the api key so:

from watson_developer_cloud import AlchemyLanguageV1
alchemy_language = AlchemyLanguageV1(api_key='THE_API_KEY')

所以，这是问题的答案：您使用 api_key 变量来保存键的值，然后调用 watson-developer-cloud 模块，不 alchemyapi 模块。将Alchemy服务绑定到应用程序后，可以通过编程方式从服务凭据中提取API密钥。

So, here is the answer to the question: you use the api_key variable to hold the value of the key, and you call the watson-developer-cloud module, NOT the alchemyapi module. You can extract the API key programmatically from the service credentials when you bind the Alchemy service to the app.
