Node 400error solution: 1, view the nodeJS request HTTP error information; 2, use the JavaScript encodeURI () function to encode the Chinese url, using syntax such as "encodeURI (URIstring)".

This article operating environment: Windows7 system, nodejs10.16.2 version, Dell G3 computer.

NodeJS request HTTP error: 4000.Please use the JavaScript encodeURI () function to encode the url containing Chinese

JavaScript Global object

Definition and usage

The encodeURI () function encodes the string as URI.

The syntax encodeURI (URIstring) parameter describes the URIstring required. A string containing URI or other text to be encoded. Return value

A copy of the URIstring in which some characters will be replaced by hexadecimal escape sequences.

Description

This method does not encode ASCII letters and numbers, nor does it encode these ASCII punctuation marks:-_. ! ~ * ().

The purpose of this method is to fully encode URI, so the encodeURI () function does not escape the following ASCII punctuation marks with special meaning in URI:; /?: @ & = + $, #

Tips and comments

Tip: if the URI component contains delimiters, such as? And #, you should use the encodeURIComponent () method to code each component separately.

Example

In this example, we will use encodeURI () to encode URI:

[xss_clean] (encodeURI ("http://www.w3school.com.cn")+") [xss_clean] (encodeURI ("http://www.w3school.com.cn/My first/")) [xss_clean] (encodeURI (", /?: @ & = + $#"))

Output:

Http://www.w3school.com.cnhttp://www.w3school.com.cn/My%20first/,/?:@&=+$#, thank you for your reading! This is the end of this article on "how to solve the problem of error reporting in node".
