400 Bad request: There was a problem in the JSON you submitted

[Joe_Bennett]

I've written a Python script to add static routes but I'm running into a JSON error. My original code was messy but worked, appending text to a string until the HTML body was complete

string="{"

string=string + '"name": "' + network["Name"] + '",'

string=string + '"subnet": "' + network["Network"] + '",'

string=string + '"gatewayIp":"' + gateway["GW"] + '",'

string=string + '"enabled":"true"}'

I then tried to use

payload = {

"name" : network["Name"],

"subnet": network["Network"],

"gatewayIp": gateway["GW"],

"enabled":"true"

}

which doesn't work

The output is as follows, the first line is rejected, the second works fine.

{'name': '10.2.1.0-24', 'subnet': '10.2.1.0/24', 'gatewayIp': '192.168.129.5', 'enabled': 'true'}
{"name": "10.2.1.0-24","subnet": "10.2.1.0/24","gatewayIp":"192.168.129.5","enabled":"true"}

The only difference appears to be the quote type. Is the API this picky? and is there a way to use the second code stanza to produce valid code? It works for the requests.request header, but not the body.

Thanks,

Joe

Whenever I look at json it uses the double quote " - not the single quote.  Is the single quote even valid syntax?

[DexterLaBora]

The JSON structure requires double quotes. This is not specific to the Python language, but a standard with the JSON format.

I figured it out.

import json

payload = {

"name" : network["Name"],

"subnet": network["Network"],

"gatewayIp": gateway["GW"],

"enabled":"true"

}

string=json.dumps(payload)

It's a Python dictionary and json.dumps turns it into valid json for the body. The header works because it's an HTML field and not json.
