Handling Character Display Instead of ASCII
In the provided Go code, the goal is to display an ampersand character (&) in a JSON response. However, the current code results in the ampersand being escaped as "u0026".
To address this, we need to disable HTML escaping in the JSON encoder. In Go versions prior to 1.7, this was not possible. However, Go 1.7 introduced a new option: Encoder.DisableHTMLEscaping.
This option allows us to prevent the escaping of , and & characters in JSON strings. To use this option, we need to set it on the encoder object.
enc := json.NewEncoder(os.Stdout) enc.SetEscapeHTML(false)
Once the HTML escaping is disabled, the encoder will no longer escape the ampersand character, resulting in the desired output:
Chrome browser show:
{ "key": "&" } &
Console also show:
{ "key": "&" } &
The above is the detailed content of How to Display an Ampersand (&) Unescaped in Go\'s JSON Response?. For more information, please follow other related articles on the PHP Chinese website!

Go language error handling becomes more flexible and readable through errors.Is and errors.As functions. 1.errors.Is is used to check whether the error is the same as the specified error and is suitable for the processing of the error chain. 2.errors.As can not only check the error type, but also convert the error to a specific type, which is convenient for extracting error information. Using these functions can simplify error handling logic, but pay attention to the correct delivery of error chains and avoid excessive dependence to prevent code complexity.

Use the recover() function in Go to recover from panic. The specific methods are: 1) Use recover() to capture panic in the defer function to avoid program crashes; 2) Record detailed error information for debugging; 3) Decide whether to resume program execution based on the specific situation; 4) Use with caution to avoid affecting performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
