Python3：字符串索引必须是整数

Question

I'm following the Taboola documentation to the T in order to update a campaign with retargeting audience lists, but I get this error "string indices must be integers" and I don't know what is wrong. I searched through the site but I can't find find a question with JSON request formatted like mine below.

Thank you for your help,

data = {
    "collection:" [
        "type": "INCLUDE" ,
        "collection:" [
            23950,
            23951,
            23949,
            23954,
            23953
        ]
    ]
}



#Create campaign
resp = requests.post(url="https://backstage.taboola.com/backstage/api/1.0/" + accountName + "/campaigns/" + campId + "/targeting/audience_segments", data=json.dumps(data), headers=headers)

The problem isn't specific to how JSON is formatted; especially because the error is from Python interpreter, but not the json module.

It's how you typed it.

This is trying to index a string (which must be an integer)

"collection:" [...]

What you need instead looks like a key-value pair

"collection" : [...]

Your data is not formatted correcting as per API requirements:

data = {
    "collection": {
        "type": "INCLUDE" ,
        "collection": [
            23950,
            23951,
            23949,
            23954,
            23953
        ]
    }
}
