【问题描述】:
我正在尝试使用 Lua 编程语言来使用 Web 服务。当我运行我的脚本时,我收到一个 http 错误 500。我的 API 是用 Python Flask 编写的,这是我的 Lua 脚本。
http = require("socket.http");
ltn12 = require("ltn12");
param_1 = argv[1];
param_2 = argv[2];
path = "http://www.url.com:8080/api/"
body = [[ {"number_id":"b8ce37fb-2061-4aea-975b-57a8e2d355ce","caller_number":param_1,"called_number":param_2} ]]
response_body = { }
res, code, response_headers, status = http.request
{
url = path,
method = "POST",
headers =
{
["X-Access-Key"] = "xxxxxxxxxxxxx",
["Content-Type"] = "application/json",
["Content-Length"] = body:len()
},
source = ltn12.source.string(body),
}
我收到了以下python回溯:
Expecting value: line 1 column 70 (char 69)(185.22 2.62.80)
Traceback (most recent call last):
File "/root/TVS/tokens-via-sva/app/controllers/api/codes.py", line 31, in crea te_code
data = json.loads(request.data)
File "/usr/lib/python3.6/json/__init__.py", line 354, in loads
return _default_decoder.decode(s)
File "/usr/lib/python3.6/json/decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python3.6/json/decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 70 (char 69)
问题的根源是什么?
【问题讨论】:
-
可能是请求返回了无效的 JSON,python 崩溃了。你能在调用
json.loads之前显示request.data吗? -
我收到了这个
b' {"number_id":"b8ce37fb-2061-4aea-975b-57a8e2d355ce","caller_number":caller_id_number,"called_number":caller_destination} ' -
什么是
caller_id_number?您在此处发布时是否用此字符串替换了实际数据?还是 JSON 与您给出的字符串完全匹配? -
其实我弄错了,我在后台得到的结果是
{"number_id":"b8ce37fb-2061-4aea-975b-57a8e2d355ce","caller_number":param_1,"called_number":param_2} ' -
你应该在字符串
body = [[ .... ]]而不是变量名中插入真实数据。例如,将:param_1,替换为:"]]..param_1..[[",
