# 账号密码登录
|
||
|
||
web端密码登录流程：
|
||
|
||
1. [完成人机验证](readme.md)
|
||
2. 加密登录密码，获取RSA公钥`key`与盐值`hash`**（盐值有效时间为20s）**，并连接盐值+密码字串（注意先后顺序），使用RSA公钥加密，得到base64格式密文
|
||
4. 登录操作验证，使用账号`username`**（手机号或邮箱）**+密文密码`password`+登录密钥`key`+极验`challenge`+验证结果`validate`+验证结果`seccode`
|
||
|
||
## 获取加密公钥及密码盐值1（web端）
|
||
|
||
> http://passport.bilibili.com/login?act=getkey
|
||
|
||
*方式：GET*
|
||
|
||
**json回复：**
|
||
|
||
根对象：
|
||
|
||
| 字段 | 类型 | 内容 | 备注 |
|
||
| ---- | ---- | ------------ | ---------------- |
|
||
| hash | str | 密码校验盐值 | 有效时间为20s |
|
||
| key | str | RSA公钥 | **公钥为固定值** |
|
||
|
||
**示例：**
|
||
|
||
```shell
|
||
curl 'http://passport.bilibili.com/login?act=getkey'
|
||
```
|
||
|
||
```json
|
||
{
|
||
"hash":"07c6501690c1af85",
|
||
"key":"-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDjb4V7EidX/ym28t2ybo0U6t0n\n6p4ej8VjqKHg100va6jkNbNTrLQqMCQCAYtXMXXp2Fwkk6WR+12N9zknLjf+C9sx\n/+l48mjUU8RqahiFD1XT/u2e0m2EN029OhCgkHx3Fc/KlFSIbak93EH/XlYis0w+\nXl69GV6klzgxW6d2xQIDAQAB\n-----END PUBLIC KEY-----\n"
|
||
}
|
||
```
|
||
|
||
## 获取加密公钥及密码盐值2（APP端）
|
||
|
||
> http://passport.bilibili.com/api/oauth2/getKey
|
||
|
||
*方式：POST*
|
||
|
||
**正文参数（ application/x-www-form-urlencoded ）：**
|
||
|
||
| 参数名 | 类型 | 内容 | 必要性 | 备注 |
|
||
| ------ | ---- | ------- | ----------- | ---- |
|
||
| appkey | str | APP密钥 | APP方式必要 | |
|
||
| sign | str | APP签名 | APP方式必要 | |
|
||
|
||
**json回复：**
|
||
|
||
根对象：
|
||
|
||
| 字段 | 类型 | 内容 | 备注 |
|
||
| ---- | ---- | ------------ | ---------------- |
|
||
| hash | str | 验证hash盐值 | 有效时间为20s |
|
||
| key | str | RSA公钥 | **公钥为固定值** |
|
||
|
||
**示例：**
|
||
|
||
```shell
|
||
curl --request POST 'http://passport.bilibili.com/api/oauth2/getKey'\
|
||
--data-urlencode 'appkey=1d8b6e7d45233436'\
|
||
--data-urlencode 'sign=17004c193f688f0b5665c1068e733aff'
|
||
```
|
||
|
||
```json
|
||
{
|
||
"hash":"07c6501690c1af85",
|
||
"key":"-----BEGIN PUBLIC KEY-----\nMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDjb4V7EidX/ym28t2ybo0U6t0n\n6p4ej8VjqKHg100va6jkNbNTrLQqMCQCAYtXMXXp2Fwkk6WR+12N9zknLjf+C9sx\n/+l48mjUU8RqahiFD1XT/u2e0m2EN029OhCgkHx3Fc/KlFSIbak93EH/XlYis0w+\nXl69GV6klzgxW6d2xQIDAQAB\n-----END PUBLIC KEY-----\n"
|
||
}
|
||
```
|
||
|
||
## 登录密码的加密
|
||
|
||
**注：RSA公钥一般为固定值**
|
||
|
||
```plaintext
|
||
-----BEGIN PUBLIC KEY-----
|
||
MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDjb4V7EidX/ym28t2ybo0U6t0n
|
||
6p4ej8VjqKHg100va6jkNbNTrLQqMCQCAYtXMXXp2Fwkk6WR+12N9zknLjf+C9sx
|
||
/+l48mjUU8RqahiFD1XT/u2e0m2EN029OhCgkHx3Fc/KlFSIbak93EH/XlYis0w+
|
||
Xl69GV6klzgxW6d2xQIDAQAB
|
||
-----END PUBLIC KEY-----
|
||
```
|
||
|
||
例如登录密码为：
|
||
|
||
```plaintext
|
||
BiShi22332323
|
||
```
|
||
|
||
获取到的盐值为：
|
||
|
||
```plaintext
|
||
8e0db05c46f4052c
|
||
```
|
||
|
||
那么按照`盐值`+`密码字串`连接二者得到：
|
||
|
||
```plaintext
|
||
8e0db05c46f4052cBiShi22332323
|
||
```
|
||
|
||
用公钥进行RSA加密得到base64字串：
|
||
|
||
因为公钥的**无法解密性**和盐值的**超时机制**，故无法本地验证加密结果
|
||
|
||
```plaintext
|
||
YgpjxAQ22pKa9socHIKPCZX0a/NS6Ng9Zzy+rp16b0LJGT6RHw2ERs3+ijCpG96PKTY1Baavwf0xgotmNvpl25l1KO5y4AjcqeWTzNTSVn6ejonBXGmBMybHHYawJ0aMPn1eDGpKrbI91mrF+h2x+fsnnpuZ1gheiYGzFmtshUc=
|
||
```
|
||
|
||
