网址的编码字符串(角度) [英] Encode string for URL (angular)

问题描述

我正在尝试编码一个非常复杂的字符串，以便可以将其包含在mailto中:

I'm trying to encode a string that's pretty complex, so that I can include it in a mailto:

组件:

<a href="mailto:[e-mail]?subject='Hello'&{{body}}">

TS:

import { HttpParameterCodec } from "@angular/common/http";

let body = encodeValue('This is the example body\nIt has line breaks and bullets\n\u2022bullet one\n\u2022bullet two\n\u2022bullet three')

当我尝试使用encodeValue时，出现找不到名称encodeValue.

When I try to use encodeValue, I get "cannot find name encodeValue.

如何对主体进行url编码?

How would be best to url-encode body?

推荐答案

HttpParameterCodec:是用于对URL中的参数进行编码和解码的编解码器(由HttpParams使用).

HttpParameterCodec : is a codec for encoding and decoding parameters in URLs( Used by HttpParams).

如果您需要对网址进行编码，则可以使用以下代码:

If you need to encode Url you can use the below:

encodeURI假定输入是一个完整的URI，其中可能包含一些需要编码的字符.

encodeURI assumes that the input is a complete URI that might have some characters which need encoding in it.

encodeURIComponent将对具有特殊含义的所有内容进行编码，因此可将其用于URI的组件，例如:

encodeURIComponent will encode everything with special meaning, so you use it for components of URIs, such as:

var textSample= "A sentence with symbols & characters that have special meaning?";
var uri = 'http://example.com/foo?hello=' + encodeURIComponent(textSample);
