[英]JSON output works in postman but not in python post request
[英]POST with JSON works in Postman but not in Python
包含Json数据的发布因python(2.7或3.6)失败,抛出错误“ 500 Internal server error”,但可从Postman使用。 从Windows 7命令提示符运行python脚本。
#!/usr/bin/env python
import urllib
import urllib2
url = 'http://<server>:<port>/web/services/notes2'
cont_type = 'application/json; charset=utf-8'
user_agent = 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36'
values = {
"LK_IN_BRANCH": "00123",
"LK_IN_ACCOUNT": "12345678",
"LK_IN_ENTRY_DATE": "20190315",
"LK_IN_ENTRY_TIME": "12300111",
"LK_IN_HOLD_DATE": "20190331",
"LK_IN_EMP_INITS": "QTC",
"LK_IN_COMMENT": "Comment from py script-notes2",
"LK_IN_USER_ID": "Hxxxxxxx",
"LK_IN_NOTE_GROUP": " "}
headers = {
"User-Agent": user_agent,
"Content-Type": cont_type,
"Accept": user_agent,
"Accept-Encoding": "gzip, deflate"}
try:
data = urllib.urlencode(values)
req = urllib2.Request(url, data, headers)
response = urllib2.urlopen(req)
json = response.read()
print json
except urllib2.URLError as e:
if hasattr(e, 'reason'):
print 'We failed to reach a server.'
print 'Reason: ', e.reason
if hasattr(e, 'code'):
print 'The server couldn\'t fulfill the request.'
print 'Error code: ', e.code
如果我添加“ Content-Length”作为邮递员,则收到“ 400错误的请求”错误。 邮递员控制台中的POST请求/响应
POST请求可以在我的机器上使用“请求”第3方程序包来工作,但是不幸的是,实际环境无法安装“请求”,因此需要它与标准内置python模块一起使用。 具有GET内置模块的python脚本也可以正常工作。 如果有任何问题,我将不胜感激。
您将Content-Type
标头设置为application/json
但将数据作为application/x-www-form-urlencoded
。 这可能是HTTP 400响应的原因。
尝试将数据作为JSON字符串发送:
#!/usr/bin/env python
import json
import urllib2
url = 'http://httpbin.org/post'
cont_type = 'application/json; charset=utf-8'
user_agent = 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.90 Safari/537.36'
values = {
"LK_IN_BRANCH": "00123",
"LK_IN_ACCOUNT": "12345678",
"LK_IN_ENTRY_DATE": "20190315",
"LK_IN_ENTRY_TIME": "12300111",
"LK_IN_HOLD_DATE": "20190331",
"LK_IN_EMP_INITS": "QTC",
"LK_IN_COMMENT": "Comment from py script-notes2",
"LK_IN_USER_ID": "Hxxxxxxx",
"LK_IN_NOTE_GROUP": " ",
}
headers = {
"User-Agent": user_agent,
"Content-Type": cont_type,
"Accept": user_agent,
}
try:
data = json.dumps(values)
req = urllib2.Request(url, data, headers)
response = urllib2.urlopen(req)
json = response.read()
print json
except urllib2.URLError as e:
if hasattr(e, 'reason'):
print 'We failed to reach a server.'
print 'Reason: ', e.reason
if hasattr(e, 'code'):
print 'The server couldn\'t fulfill the request.'
print 'Error code: ', e.code
