Why do I get "'str' object has no attribute 'read'" when trying to use `json.load` on a string?

AttributeError("'str' object has no attribute 'read'",)

This means exactly what it says: something tried to find a .read attribute on the object that you gave it, and you gave it an object of type str (i.e., you gave it a string).

The error occurred here:

json.load(jsonStr)['data']['children']

Well, you aren’t looking for read anywhere, so it must happen in the json.load function that you called (as indicated by the full traceback). That is because json.load is trying to .read the thing that you gave it, but you gave it jsonStr, which currently names a string (which you created by calling .read on the response).

Solution: don’t call .read yourself; the function will do this, and is expecting you to give it the response directly so that it can do so.

You could also have figured this out by reading the built-in Python documentation for the function (try help(json.load), or for the entire module (try help(json)), or by checking the documentation for those functions on http://docs.python.org .

If you get a python error like this:

AttributeError: 'str' object has no attribute 'some_method'

You probably poisoned your object accidentally by overwriting your object with a string.

How to reproduce this error in python with a few lines of code:

#!/usr/bin/env python
import json
def foobar(json):
    msg = json.loads(json)

foobar('{"batman": "yes"}')

Run it, which prints:

AttributeError: 'str' object has no attribute 'loads'

But change the name of the variablename, and it works fine:

#!/usr/bin/env python
import json
def foobar(jsonstring):
    msg = json.loads(jsonstring)

foobar('{"batman": "yes"}')

This error is caused when you tried to run a method within a string. String has a few methods, but not the one you are invoking. So stop trying to invoke a method which String does not define and start looking for where you poisoned your object.

Ok, this is an old thread but.
I had a same issue, my problem was I used json.load instead of json.loads

This way, json has no problem with loading any kind of dictionary.

Official documentation

json.load – Deserialize fp (a .read()-supporting text file or binary file containing a JSON document) to a Python object using this conversion table.

json.loads – Deserialize s (a str, bytes or bytearray instance containing a JSON document) to a Python object using this conversion table.

You need to open the file first. This doesn’t work:

json_file = json.load('test.json')

But this works:

f = open('test.json')
json_file = json.load(f)

Instead of json.load() use json.loads() and it would work:
ex:

import json
from json import dumps

strinjJson = '{"event_type": "affected_element_added"}'
data = json.loads(strinjJson)
print(data)

So, don’t use json.load(data.read()) use json.loads(data.read()):

def findMailOfDev(fileName):
    file=open(fileName,'r')
    data=file.read();
    data=json.loads(data)
    return data['mail']

use json.loads() function , put the s after that … just a mistake btw i just realized after i searched error

def getEntries (self, sub):
url = 'http://www.reddit.com/'
if (sub != ''):
    url += 'r/' + sub

request = urllib2.Request (url + 
    '.json', None, {'User-Agent' : 'Reddit desktop client by /user/RobinJ1995/'})
response = urllib2.urlopen (request)
jsonStr = response.read()

return json.loads(jsonStr)['data']['children']

try this

Open the file as a text file first

json_data = open("data.json", "r")

Now load it to dict

dict_data = json.load(json_data)

If you need to convert string to json. Then use loads() method instead of load(). load() function uses to load data from a file so used loads() to convert string to json object.

j_obj = json.loads('["label" : "data"]')
