Parsing the body of the HTTP request in Python

There is an HTTP request stored in a string variable. For example:

POST /api/integration/test.json HTTP/1.1 Host: 192.168.0.221:1028 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:49.0) Gecko/20100101 Firefox/49.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate X-Compress: off Connection: keep-alive Upgrade-Insecure-Requests: 1 Content-Type: multipart/form-data; boundary=---------------------------16270120918082 Content-Length: 693 -----------------------------16270120918082 Content-Disposition: form-data; name="field1" field1value -----------------------------16270120918082 Content-Disposition: form-data; name="field2" field2value -----------------------------16270120918082 Content-Disposition: form-data; name="file"; filename="1.json" Content-Type: application/octet-stream { "ipAddress":"192.168.0.221", "port":1028, } -----------------------------16270120918082-- 

Question: how in Python to parse this string into some object that provides a convenient interface for accessing the request data (especially the body)?

I used HttpParser when there were enough GET requests. The module is good for heading parsing, but it does almost nothing with the body.
