TypeError: b'1' is not JSON serializable
提问by Teodora
I am trying to send a POST request as JSON.
我正在尝试将 POST 请求作为 JSON 发送。
*email variable is of type "bytes"
*email 变量的类型为“字节”
def request_to_SEND(email, index):
url = "....."
data = {
"body": email.decode('utf-8'),
"query_id": index,
"debug": 1,
"client_id": "1",
"campaign_id": 1,
"meta": {"content_type": "mime"}
}
headers = {'Content-type': 'application/json'}
try:
response = requests.post(url, data=json.dumps(data), headers=headers)
except requests.ConnectionError:
sys.exit()
return response
I get the error:
我收到错误：
File "C:\Python34\lib\json\encoder.py", line 173, in default
raise TypeError(repr(o) + " is not JSON serializable")
TypeError: b'1' is not JSON serializable
Could you please tell me what is it that I am doing wrong?
你能告诉我我做错了什么吗？

This is happening because you're passing a bytesobject in the datadict (b'1', specifically), probably as the value of index. You need to decode it to a strobject before json.dumpscan work with it:
发生这种情况是因为您bytes在datadict 中传递了一个对象（b'1'特别是 ），可能作为index. 您需要str先将其解码为一个对象，然后json.dumps才能使用它：
data = {
"body": email.decode('utf-8'),
"query_id": index.decode('utf-8'), # decode it here
"debug": 1,
"client_id": "1",
"campaign_id": 1,
"meta": {"content_type": "mime"}
}
