问题描述
当我运行以下代码时，出现500服务器错误。我不确定是什么错误。
我正在使用python urllib请求上传文件。
query=''.join(("\"{\"query\":\"mutation($file: Upload!){\\n"," deployPlugin(fileUpload:$file){\\n"," id\\n"," status\\n"," }\\n","}\",\"variables\":{\"file\":null},\"operationName\":null}\""))
urlData = {"operations" : query,"map": "{\"file0\":[\"variables.file\"]}",\
"file0":"@" + local_filename
}
data = json.dumps(urlData)
print (data)
req = request.Request(apiURL,data = bytes(data.encode("utf-8")))
#print(query)
# Add the username and password.
# If we knew the realm,we Could use it instead of None.
req.add_header("Authorization","%s" % auth_header)
# Make a call to function
response = urllib.request.urlopen(req)
responseData = json.load(response)
print(responseData)
