我写的代码和改进代码chatgpt4,结果是代码并没有简单化 make this rust language simpler pub fn download_url_as_string(user_agent: &str, url: &str) -> Result<String, ApplicationError> { Client::builder() .default_headers(get_default_headers(user_agent)?) .build() .report_context(ApplicationError:ownloadUrl)? .get(url) .send() .report_context(ApplicationError:ownloadUrl)? .text() .report_context(ApplicationError:ownloadUrl) } Certainly. Below is a simplified version of the original Rust function download_url_as_string. The original function is written in a chained manner, making it concise but potentially difficult to read. I've broken down the function into individual steps to make the code more straightforward. Additionally, I've added comments to describe what each step is doing. rust Copy code pub fn download_url_as_string(user_agent: &str, url: &str) -> Result<String, ApplicationError> { // Build the HTTP client with default headers let mut headers = get_default_headers(user_agent)?; let client = match Client::builder().default_headers(headers).build() { Ok(c) => c, Err(_) => return Err(ApplicationError:ownloadUrl), }; // Send GET request to the specified URL let mut request = match client.get(url).send() { Ok(r) => r, Err(_) => return Err(ApplicationError:ownloadUrl), }; // Read the text from the response let text = match request.text() { Ok(t) => t, Err(_) => return Err(ApplicationError:ownloadUrl), }; // Return the fetched text Ok(text) } Here's a breakdown of the changes: The client building step has been separated out. The headers are obtained using the get_default_headers function, and then the client is built using Client::builder().default_headers(headers).build(). Any errors at this step will return ApplicationError:ownloadUrl. The GET request to the specified URL is then sent using client.get(url).send(). Errors at this point will also return ApplicationError:ownloadUrl. The text from the response is obtained using request.text(). Again, any error will return ApplicationError:ownloadUrl. Finally, if all the steps succeed, the text is returned wrapped in an Ok variant of the Result type. This should help in understanding what the function is doing at each step and make it easier to debug if issues arise. |
