Question

我有下面的python脚本正在进行成功的休息Web服务请求，但在服务器发回HTTP 200之后再抛出404。我可以看到其余的Web服务Web应用程序日志成功返回以下JSON响应。有关如何进一步解决此问题或可能导致以下错误的任何想法？

最后执行的Python行：

result = urllib2.urlopen(req)

来自Rest API端点的JSON响应：

response{"status":"SUCCESS","reason":null,"location":null,"details":null,"errorDetails":{}}

Python脚本：

        tmp_file.write(output)
        tmp_file.close()
        output = call_webservice()

            out_message = output['reason']
            exit_code = 1

    except Exception, ex:

你拼错了Accept标题：

req.add_header('Accept', 'arpplication/json')

更正application的拼写：

req.add_header('Accept', 'application/json')

即使发送了HTTP 200，urllib2.urlopen（req）也会返回404
