If the URL that is used to send a request is invalid, Message Service (MNS) returns the following error message: Http request URL format invalid. This topic describes how to troubleshoot the issue in different scenarios.

Issue

The following error message is returned by MNS:
[Error Code]:InvalidRequestURL, [Message]:Http request URL format invalid

Cause

The following causes may exist:
  • Cause 1: When you use an SDK, the specified MNS endpoint is invalid.
  • Cause 2: When you call a queue-related API operation, the specified protocol version does not match the specified request URL.

Solution

The following solutions are provided based on the cause:

Solution 1 to Cause 1

If you use an MNS SDK, check whether the specified MNS endpoint in the code is valid. The following example shows how to obtain a valid MNS endpoint.

Note In most cases, this issue occurs if you specify a queue endpoint instead of an MNS endpoint in the code. Example:
  • MNS endpoint: String endpoint = "http://44404.mns.cn-beijing.aliyuncs.com/".
  • Queue endpoint: String endpoint = "http://44404.mns.cn-beijing.aliyuncs.com/queues/LTQueue/".
  1. Log on to the MNS console.
  2. Select the region where the MNS queue that you want to use resides and click Queues. On the Queues page, find the queue.
  3. Click Get Endpoint. getendpointsteps
  4. In the message that appears, copy and use the required endpoint to check whether the issue persists.

Solution 2 to Cause 2

If you call a queue-related API operation, check whether you use the latest API version or the previous API version. Make sure that the request URL complies with the specifications of the specified API version. The following table describes the latest API version and previous API version.

API versionCreateQueueSendMessage
Latest version (x-mns-version:2015-06-06)PUT /queues/[$Queue_Name]POST /queues/[$Queue_Name]/messages
Previous version (x-mqs-version:2014-07-08)PUT /[$Queue_Name]POST /[$Queue_Name]/messages
Note [$Queue_Name] specifies the name of a queue.
