[ ] 创建请求失败

Error message

[%s] 创建请求失败: %w

What it means

http.NewRequestWithContext failed while building the POST request to the API URL. This occurs before any network I/O and almost always means the URL failed to parse or the body/io.Reader itself errored.

Solutions

1. Print/validate apiURL before constructing the request (url.Parse the constant at init)
2. Check the wrapped error's message for 'parse ...: invalid ...' hints
3. Fix the configuration or constant supplying apiURL

Example fix

// before
req, err := http.NewRequestWithContext(ctx, "POST", apiURL, bytes.NewBuffer(jsonData))
// after
if _, perr := url.Parse(apiURL); perr != nil {
    return nil, fmt.Errorf("无效的API地址 %q: %w", apiURL, perr)
}
req, err := http.NewRequestWithContext(ctx, "POST", apiURL, bytes.NewBuffer(jsonData))

u, err := url.Parse(apiURL)
if err != nil || u.Scheme == "" || u.Host == "" {
    return fmt.Errorf("无效的API地址: %q", apiURL)
}

req, err := http.NewRequestWithContext(ctx, "POST", apiURL, bytes.NewBuffer(jsonData))
if err != nil {
    return nil, fmt.Errorf("[%s] 创建请求失败: %w", pluginName, err)
}

When it happens

Trigger: apiURL is malformed (bad scheme, spaces, control characters) or the request body reader returns an error when NewRequest reads it into memory.

Common situations: apiURL built from an empty or misconfigured base URL; configuration containing whitespace or invalid characters interpolated into the URL; constant leaked into apiURL.

Understand the failure class

Background: "Invalid URL" / "URL cannot be empty": fix the malformed or missing URL behind request-construction failures — this error's family across 50 libraries.
