Jasper服务器rest_v2 api在python中使用请求

Question

我正在使用jasperserver rest_v2 web服务。我在python中使用请求模块来命中api。在jasper服务器上的报告正在执行和 报告网址如下：

http://localhost:8080/jasperserver/rest_v2/reportExecutions

我得到了像这样的json响应：

{
  "status": "ready",
  "totalPages": 0,
  "requestId": "d0ae905c-1538-4e40-b5ad-c145f521707c",
  "reportURI": "/reports/Invoices/COD",
  "exports": [
    {
      "id": "49f47112-4698-4398-9ed8-a62d552a7aa5",
      "status": "ready",
      "outputResource": {
        "contentType": "application/pdf",
        "fileName": "COD.pdf",
        "outputFinal": true
      }
    }
  ]
}

这意味着我的报告已经执行。

然后我点击以下网址下载报告输出。

http://localhost:8080/jasperserver/rest_v2/reportExecutions/d0ae90c-1538-4e40-b5ad-c145f521707c/exports/49f47112-4698-4398-9ed8-a62d552a7aa5/outputResource

它给出了以下404状态代码的响应：

{
  "message": "Resource d0ae95c-1538-4e40-b5ad-c145f521707c not found.",
  "errorCode": "resource.not.found",
  "parameters": [
    "d0ae95c-1538-4e40-b5ad-c145f521707c"
  ]
}

然后我使用以下网址检查了我的报告状态：

http://localhost:8080/jasperserver/rest_v2/reportExecutions/d0ae905c-1538-4e40-b5ad-c145f521707c

我得到了回复404并跟随json：

{
  "message": "Resource d0ae905c-1538-4e40-b5ad-c145f521707c not found.",
  "errorCode": "resource.not.found",
  "parameters": [
    "d0ae905c-1538-4e40-b5ad-c145f521707c"
  ]
}

使用Postman完全一样正常。 注意：我传递了有效的凭据和相应的标题。

以下是我对此的django观点：

class JasperView(View):
    template = "report.html"

    def get_token(self):
        username = "zeeshan"
        password = "zeeshan"
        token = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')
        return token

    def get(self, request, *args, **kwargs):
        return render(request, self.template)

    def post(self, request, *args, **kwargs):
        token = self.get_token()
        data = """

        response = requests.post(url="http://localhost:8080/jasperserver/rest_v2/reportExecutions",

帮助。
