Extracting specific JSON values in python

JSON return from spotify api. Example:
{
"tracks": {
"href": "https://api.spotify.com/v1/search?query=Stero+Hearts&type=track&offset=0&limit=1",
"items": [
{
"album": {
"album_type": "album",
"artists": [
{
"external_urls": {
"spotify": "https://open.spotify.com/artist/4IJczjB0fJ04gs4uvP0Fli"
},
"href": "https://api.spotify.com/v1/artists/4IJczjB0fJ04gs4uvP0Fli",
"id": "4IJczjB0fJ04gs4uvP0Fli",
"name": "Gym Class Heroes",
"type": "artist",
"uri": "spotify:artist:4IJczjB0fJ04gs4uvP0Fli"
}
]
}
}
]
}

The aim is to convert word search to link in a cli application.
I tried load.json which i saw in some website and also tried def.
I expected the program to find out the artist name and uri from the json and print it in the cli interface.

You are iterating over the encoded json string:
auth_response = requests.get(link, headers=header)
for d in auth_response:
Python is complaining that you aren't providing a numerical index, which is correct as auth_response is just a string!
You should call json.loads to decode the string, and then you can iterate over it.
auth_response = requests.get(link, headers=header)
decoded_auth_response = json.loads(auth_response)
data_by_user = {}
for d in decoded_auth_response:
data_by_user[d["artist"]] = d
As you haven't provided the full json output from the API call I'm not sure what data is actually in decoded_auth_response, and you haven't described what your expected output would look like, so you may need to do some more work to find the correct data in each iteration.

The result from requests.get() is a requests.Response object. As far as I can see you want to iterate over the response body which is JSON. The requests.Response object has a .json() method which returns a dict from the response JSON.
Looking at the response you would probably want to iterate over resp_json['tracks']['items'] which is a list.
So to summarize your code should look something like this:
auth_response = requests.get(link, headers=header)
items = auth_response.json()['tracks']['items']
for d in items:
print(d)

JSON key and value

I am trying to get the values from objects in the following JSON response:
[
{
"compositionId": "-Mkl92Mii2UF3xzi1q7L",
"compositionName": null,
"mainComposition": true,
"animation": {
"state": "Out1"
}
},
{
"compositionId": "bbbbbb",
"compositionName": null,
"mainComposition": true,
"animation": {
"state": "Out1"
}
}
]
What I would like to get in a loop is all the compositionIds but I don't get the correct output.
I can dump the complete JSON with the following code:
import requests
import json
url = 'http://192.168.1.33/data'
r = requests.get(url)
data = json.loads(r.content.decode())
json_str = json.dumps(data)
resp = json.loads(json_str)
print (resp)

You can simply use the requests module, in fact it does provide a builtin json decoder, that is the .json() function. Done that, you can simply iterate over your json objects with a simple for.
You could do something similar to this:
import requests
url = 'http://192.168.1.33/data'
r = requests.get(url)
my_json_file = r.json()
for json_object in my_json_file:
# Do something with json_object['compoitionId']
pass

Try something like this:
import requests
import json
url = 'http://192.168.1.33/data'
r = requests.get(url)
data = json.loads(r.content.decode())
print([d['compositionId'] for d in data])

How can I filter author Ids out of this json?

I'm specifically trying to get the id out of "author" to write it to a json file, But I have no idea how to filter out the ids and then write them to the file. Im kinda new to this
[
{
"id":"865170257588125696",
"content":"<#862323352869797948> I set your AFK: yes",
"channel_id":"859115914444537876",
"author":{
"id":"155149108183695360",
"username":"Dyno",
"discriminator":"3861",
}
},
{
"id":"865170254677409812",
"content":"?afk yes",
"channel_id":"859115914444537876",
"author":{
"id":"862323352869797948",
"username":"zz2w2wfff2",
"discriminator":"2401"
}
},
{
"id":"865170247349567488",
"content":"Meh",
"channel_id":"859115914444537876",
"author":{
"id":"862323352869797948",
"username":"zz2w2wfff2",
"discriminator":"2401"
}
}
]
This is all I have:
r = requests.get("https://discord.com/api/v9/channels/" + channelid + "/messages?limit=50", headers=headers)
if r.status_code == 200:
authorid = r.json()[0]["author"]["id"]
for authorid in r.text:
print(authorid)
All that did was show gibberish when I ran it.

Based on your code, this should get you going. You don't need to access the r response anymore after you've parsed it using r.json():
r = requests.get("https://discord.com/api/v9/channels/" + channelid + "/messages?limit=50", headers=headers)
r.raise_for_status()
data = r.json()
for message in data:
print(message["author"]["id"])

Need to use functionality of iLoc, but for Dictionary values (text)

I am trying to make an API call that pulls the value of a column within a spreadsheet and sends it as a param within the API call.
I've done this successfully before with this code, but that was for integer values. Now I need to do it with text and they are stored as Dict values which give me an error.
Here is what I'm trying to use:
for i in range(10):
r = requests.post(
url = "DummyAPIEndpoint",
headers = {
'Authorization': 'ApiKey DummyKey',
'Content-Type' : 'application/json'
},
params = {
{
'data' : mt.iloc [i,0]
}
}
)
print(r)
When my values are all integers, the mt.iloc [i,0] pulls every entry in the first column and fires an API call with that value under 'data'. However, since this content is text, I get the error:
TypeError: unhashable type: 'dict'
I understand why I'm getting this error, I'm just not sure what to do about it.
How can I add the text value of the column within the spreadsheet as the param "data"?

The code has params in an extra set of braces.
This is interpreted as a dict.
You don't want that.
You'll want to remove the extra braces like this:
for i in range(10):
r = requests.post(
url = "DummyAPIEndpoint",
headers = {
'Authorization': 'ApiKey DummyKey',
'Content-Type' : 'application/json'
},
params = {
'data' : mt.iloc [i,0]
}
)
print(r)

Convert Python dictionary to a JSON array

Here's my function which connects to an API:
def order_summary():
"""Get order summary for a specific order"""
# Oauth2 params
headerKey = api_login()
headers = {'Authorization': headerKey}
# Payload params
payloadOrderSum = {
"domainId": 15,
"domainName": "SGL",
"orderId": 3018361
}
# API response
orderSumResp = requests.post(url + "order/summary", data=payloadOrderSum, headers=headers)
print(orderSumResp.content)
The API expects a JSON array as Payload Params which essentially looks like that:
[
{
"domainId": 0,
"domainName": "string",
"orderId": 0
}
]
The other endpoints I coded for on this API didn't need for the params to be an array so I could just use them as is and send them as a dictionary and it worked.
I've tried a couple things using the JSON library but I can't seem to get it to work. I saw that the JSonEncoder converts lists and tuples to JSON arrays but I couldn't figure it out.
Not sure what other info I could provide but just ask if there are any.
Thanks!

Wrap payloadOrderSum into a list:
payloadOrderSum = {
"domainId": 15,
"domainName": "SGL",
"orderId": 3018361
}
orderSumResp = requests.post(url + "order/summary", json=[payloadOrderSum], headers=headers)
Note that I used json kwarg instead of data (added in version 2.4.2).

dump your dict with json.dumps requests-doc
r = requests.post(url, data=json.dumps(payload))

It could help if you specify what you tried with the JSON library.
However, you might wanna try this if you haven't already done so:
import json
payloadOrderSum = json.dumps(
{
"domainId": 15,
"domainName": "SGL",
"orderId": 3018361
}
)
