How to solve the node 400 error problem?
nodeJS request HTTP error: 400, please use the JavaScript encodeURI() function to encode the URL containing Chinese
JavaScript global object
Definition and usage
encodeURI() function can encode a string as a URI.
Syntax
encodeURI(URIstring)
| Parameters | Description |
|---|---|
| URIstring | Required. A string containing the URI or other text to be encoded. |
Return value
A copy of the URIstring, with some characters replaced by hexadecimal escape sequences.
Description
This method does not encode ASCII letters and numbers, nor does it encode these ASCII punctuation characters: - _ . ! ~ * ' ( ) .
The purpose of this method is to completely encode the URI, so the encodeURI() function will not escape the following ASCII punctuation marks that have special meanings in the URI: ;/?:@& = $,
#Tips and comments
Tips: If the URI component contains delimiters, such as? and #, you should use the encodeURIComponent() method to encode each component separately.
Example
In this example, we will use encodeURI() to encode the URI:
<script type="text/javascript">
document.write(encodeURI("http://www.w3school.com.cn")+ "<br />")
document.write(encodeURI("http://www.w3school.com.cn/My first/"))
document.write(encodeURI(",/?:@&=+$#"))
</script>
Output:
http://www.w3school.com.cn http://www.w3school.com.cn/My%20first/ ,/?:@&=+$#
