Dify version

0.6.10

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

build ai agent, public run app.
get the image url markdown format as follows:
{"text_to_texture": "{"url": ""}"}

but dify will show cut the url to beijing.aliyuncs.com/7d/fe/20240618/65a8eb47/20240618_125615_seed-47593_000_17bb2fba-2d2f-11ef-bca9-00163e0a1f6e.jpg

and then shows error.

iShot_2024-06-18_14 15 30

✔️ Expected Behavior

markdown url format shows OK.

❌ Actual Behavior

image shows error, because dify cuts url before the seperator charactor '?'
such as the original url is :https://dashscope-result-bj.oss-cn-beijing.aliyuncs.com/7d/fe/20240618/65a8eb47/20240618_125615_seed-47593_000_17bb2fba-2d2f-11ef-bca9-00163e0a1f6e.jpg?Expires=1718772975&OSSAccessKeyId=LTAI5tQZd8AEcZX6KZV4G8qL&Signature=8GVAHzDiboYAnBhArCJ01GorkMg%3D

the image url finally will be :https://dashscope-result-bj.oss-cn-beijing.aliyuncs.com/7d/fe/20240618/65a8eb47/20240618_125615_seed-47593_000_17bb2fba-2d2f-11ef-bca9-00163e0a1f6e.jpg

@guobaozu Hello there! I'm here to assist you with bug fixes, questions, and contributions. Let me know how I can help while we wait for a human maintainer.

The issue you're encountering with URL truncation in markdown format is likely related to how the Markdown component processes URLs. The Markdown component in Dify uses the ReactMarkdown library with several plugins, including RemarkGfm, which should handle URLs correctly. However, it seems that URLs containing query parameters are being truncated.

To address this, you might want to check the Markdown component implementation in web/app/components/base/markdown.tsx to ensure that URLs with query parameters are handled correctly. Here is the relevant part of the Markdown component:

<ReactMarkdown
  remarkPlugins={[[RemarkMath, { singleDollarTextMath: false }], RemarkGfm, RemarkBreaks]}
  rehypePlugins={[
    RehypeKatex as any,
  ]}
  components={{
    // other components
  }}
  linkTarget='_blank'
>
  {latexContent}
</ReactMarkdown>

If the issue persists, you might need to look into the specific handling of URLs within the ReactMarkdown and RemarkGfm plugins to ensure they are not inadvertently truncating URLs with query parameters.

Additionally, there are environment-specific settings in the Docker setup for Dify that could affect URL handling. Ensure that the relevant environment variables such as CONSOLE_API_URL, APP_API_URL, CONSOLE_WEB_URL, SERVICE_API_URL, and APP_WEB_URL are correctly configured in your docker-compose.yaml file and .env files [1][2][3].

If you need further assistance, you might want to review the tests related to URL handling in api/tests/unit_tests/libs/test_yarl.py to ensure that URL concatenation and handling are working as expected [4].
