 Json中含有 特殊字符

String values encode as JSON strings coerced to valid UTF-8, replacing invalid bytes with the Unicode replacement rune. The angle brackets "<" and ">" are escaped to "\u003c" and "\u003e" to keep some browsers from misinterpreting JSON output as HTML. Ampersand "&" is also escaped to "\u0026" for the same reason. This escaping can be disabled using an Encoder with DisableHTMLEscaping.

方法1:

  data := json.RawMessage(`"key": "http://www.baidu.com?a=c&b=d&e=d"`)
  bytes, err := data.MarshalJSON()



方法2:
From go1.7

enc := json.NewEncoder(os.Stdout)

enc.SetEscapeHTML(false)
