使用python向RESTful API发出请求

本文介绍了使用python向RESTful API发出请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个RESTful API，我已经在EC2实例上使用Elasticsearch的一个实现来暴露了索引一个内容的语料库。我可以通过从我的终端（MacOSX）运行以下内容来查询搜索：

I have a RESTful API that I have exposed using an implementation of Elasticsearch on an EC2 instance to index a corpus of content. I can can query the search by running the following from my terminal (MacOSX):

curl -XGET 'ES_search_demo/document/record/_search?pretty=true' -d '{ "query": { "bool": { "must": [ { "text": { "record.document": "SOME_JOURNAL" } }, { "text": { "record.articleTitle": "farmers" } } ], "must_not": [], "should": [] } }, "from": 0, "size": 50, "sort": [], "facets": {} }'

如何使用 python将其转换为API请求/ request 或 python / urllib2 （不知道要去哪一个 - 一直在使用urllib2，但听到请求更好...）我是否以标题或其他方式传递？

How do I turn above into a API request using python/requests or python/urllib2 (not sure which one to go for - have been using urllib2, but hear requests is better...)? Do I pass as a header or otherwise?

推荐答案

使用请求：

import requests url = 'ES_search_demo/document/record/_search?pretty=true' data = '''{ "query": { "bool": { "must": [ { "text": { "record.document": "SOME_JOURNAL" } }, { "text": { "record.articleTitle": "farmers" } } ], "must_not": [], "should": [] } }, "from": 0, "size": 50, "sort": [], "facets": {} }''' response = requests.post(url, data=data)

根据您的API返回的响应类型，您可能需要查看 respo nse.text 或 response.json（）（或可能检查 response.status_code ）。请参阅快速入门文档此处，特别是本节。

Depending on what kind of response your API returns, you will then probably want to look at response.text or response.json() (or possibly inspect response.status_code first). See the quickstart docs here, especially this section.
