我正在对带有JSON文件作为有效负载的API的请求进行POST调用。
从API日志中我可以看出，一个令牌正被添加到有效载荷中，这会导致接收API出现问题。
以下是帖子请求的代码：
import requests
def post_to_api(self, spider):
url = 'http://106309.nitrousapp.com:3000/api/v1/imports/batch_create'
headers = {'X-Api-Key': 'TOHhsxPyJnpZcUhLMMqj0XwipSY48PQxCXzIsW8FFpMt', 'Content-Type': 'application/json'}
r = requests.post(url, files={'file': open('fancy_items.json', 'r+b')}, headers=headers)
print r.json
原始JSON是正确的，在JSONLint上检查它。
然而，查看API上的日志，它会在文件底部显示一个像这样添加的令牌：
{"name": "Mystical Fire Colorant", "country": "USA", "price": "75", "category_old": "Sports & Outdoors", "image_url": "http://thingd-media-ec1.thefancy.com/default/701418813568058872_5171d5c216c7.jpg", "i
nterest": "113", "link": "https://fancy.com/things/701418813568058872/Mystical-Fire-Colorant", "company": "Fancy"}]}
--0c5171b3fe574bdb921838ef81c437c2--
':
我尝试过对API的手动调用，并且没有添加此令牌，因此我正在考虑请求或Python正在做的事情。
以下是API日志的总JSON输出：

答案 0 :(得分：1)
看起来requests正在提交multipart/form-data编码的POST请求，因为您正在加载文件（即您的files调用中有requests.post()个参数）。 POST a Multipart-Encoded File section of the requests documentation中描述了此行为。另外，有关POST请求中不同编码的详细信息，请参阅：What does enctype='multipart/form-data' mean?
我认为您尝试做的是POST一些JSON，而不是发送包含 JSON的文件。这是一些粗略的示例代码：
import requests
import json
def post_to_api(self, spider):
url = 'http://106309.nitrousapp.com:3000/api/v1/imports/batch_create'
headers = {'X-Api-Key': 'TOHhsxPyJnpZcUhLMMqj0XwipSY48PQxCXzIsW8FFpMt', 'Content-Type': 'application/json'}
with open('fancy_items.json') as f:
json_data = json.load(f)
r = requests.post(url, json=json_data, headers=headers)
print r.status_code
print r.content
有关详细信息，请参阅More complicated POST requests in the requests documentation。
P.S。如果这是一个真正的API密钥，您可能希望在某个时候撤销它。
