@Liangpi000 你好！我是Dosu，一个可以帮助解决 bug、回答问题和成为贡献者的机器人。我会在等待人类维护者的过程中帮助你解决问题。

The error you're encountering indicates that the Content-Length header is missing in the request for the multimodal URL when using the 通义千问视觉模型. This header is crucial for specifying the size of the request body, especially when uploading files.

To address this issue, you should ensure that the Content-Length header is correctly set in the HTTP request. This typically involves calculating the size of the file being uploaded and including it in the request headers. If you're using a library or framework to handle HTTP requests, it might automatically set this header for you when you provide the file data correctly.

If you're modifying the code directly, look for the part of the code where the HTTP request is constructed for file uploads and ensure that the Content-Length is included in the headers. If this is part of the lobe-chat framework, you might need to check the relevant part of the codebase where file uploads are handled and adjust it to include this header.

Unfortunately, I couldn't find specific details in the lobe-chat codebase about where the Content-Length header is set for file uploads, so you might need to explore the code related to HTTP request construction for multimodal requests.

To continue talking to Dosu, mention @dosu.

• The uploaded images need to use the url image of Alibaba Cloud's OSS. You can use my image url for testing: https://dashscope.oss-cn-beijing.aliyuncs.com/images/dog_and_girl.jpeg
