GoogleQRCode的介绍很久没有出现在网上了,直接从chart页过去找也很麻烦,而且还经常 找不到。
在这里贴个链接:https://developers.google.com/chart/infographics/docs/qr_codes
再来个简单的说明,生成QRCode真的很简单(以前也写过博客介绍过,其实我这次只是想贴个链接而已),上一次是: google QRCode,在之前还有一篇:QR CODE,看文中的链接已经变了,原文中说的:https://code.google.com/apis/chart/docs/gallery/qr_codes.html,已经是404了。。。
用法很简单:
1、接口地址:https://chart.googleapis.com/chart?
2、几个参数:
Parameter | Required or Optional | Description |
---|---|---|
cht=qr |
Required | Specifies a QR code. |
chs=<width>x<height> |
Required | Image size. |
chl=<data> |
Required | The data to encode. Data can be digits (0-9), alphanumeric characters, binary bytes of data, or Kanji. You cannot mix data types within a QR code. The data must be UTF-8 URL-encoded. Note that URLs have a 2K maximum length, so if you want to encode more than 2K bytes (minus the other URL characters), you will have to send your data using POST. |
choe=<output_encoding> |
Optional | How to encode the data in the QR code. Here are the available values:
|
chld=<error_correction_level>|<margin> |
Optional |
|
是不是很简单?
