python - GraphQL 和 Python with Json - 带有未转义字符的语法错误

Question

我正在尝试发布 GraphQL 突变，但遇到了我无法弄清楚的语法错误。我发现存在关于转义/未转义字符的错误。我尝试过转义、双引号、单引号、不引号。我似乎无法摆脱这个问题。代码下的回溯。

# http headers for api call
headers = {
    'accept': "application/json",
    'content-type':"application/json",
    'authorization': "bearer " + token,
}

# create inventory variable for mutation 
# will convert the csv to the json input in production
inventory:[{"supplier_id":24522,"supplier_part_number":"1-1002-9-SN","quantity_on_hand":5,"item_next_availability_date":"05-01-2018T00:00:00", "discontinued":true}]


# payload of the json query to pass to the API
#GraphQL Query to pull in Purchase Order Data 
payload = '''
{"query":"mutation save_inventory($inventory: [inventoryInput]!) {
  inventory {
    save(inventory: $inventory, dry_run: true) {
      handle
    }
  }
}"}
'''

# send API call and assign response to variable
response = requests.post(api_url, data=payload, headers=headers)

错误，我无法弄清楚下面的内容。

  {"errors":[{"message":"Syntax Error GraphQL (1:1) Unexpected <EOF>\n\n1: \n   ^\n","category":"graphql","locations":[{"l
    ine":1,"column":1}]}]}

我的Python很生疏，但我相信你想使用json而不是data。您也没有传入您定义的 inventory 变量。尝试这样的事情:

json = {
  "query": '''   
    mutation save_inventory($inventory: [inventoryInput]!) {
      inventory {
        save(inventory: $inventory, dry_run: true) {
        handle
      }
    }
  }
  ''',
  "variables": {
    "inventory": inventory
  }
}

response = requests.post(api_url, json=json, headers=headers)
