Str to json

To convert python strings to json objects, you need to use the loads function of the json module

Import json str ='{"accessToken": "521de21161b23988173e6f7f48f9ee96e28" "User-Agent": "Apache-HttpClient/4.5.2 (Java/1.8.0_131)"}'j = json.loads (str) print (j) print (type (j)) 1 2 3 4 5 6 7

Output

{'accessToken':' 521de21161b23988173e6f7f48f9ee96e288, 'User-Agent':' Apache-HttpClient/4.5.2 (Java/1.8.0_131)'} 1 2 json to strimport json j = {"accessToken": "521de21161b23988173e6f7f48f9ee96e28" User-Agent: "Apache-HttpClient/4.5.2 (Java/1.8.0_131)"} str = json.dumps (j) print (str) print (type (str)) 1 2 3 4 5 6 7

Output

{"accessToken": "521de21161b23988173e6f7f48f9ee96e28", "User-Agent": "Apache-HttpClient/4.5.2 (Java/1.8.0_131)"} 1 2 questions

The main purpose of this article is to solve a problem with mark. When converting str to json, the problem of quotation marks in str format leads to failure and error report.

Look at the following code

Import json str = "{'accessToken':' 521de21161b23988173e6f7f48f9ee96e28' 'User-Agent':' Apache-HttpClient/4.5.2 (Java/1.8.0_131)'} "j = json.loads (str) print (j) print (type (j)) 1 2 3 4 5 6 7

At first glance, there was no problem, but there was a mistake.

Json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1) 1

Why?

In the string, the double quotation marks are in the periphery and the single quotation marks are embedded, causing the conversion to fail
