这是从fiddler抓到的，通过其他软件发包没有任何问题：
然后我通过python 发送请求发现 返回 签名失败：

通过fiddler发现python 发送的请求中参数已被修改：

requests发包会自动url编码，你需要把%2F改回/

```
试试 不是post(url,data = val,headers = headers)这样吗，原来可以省略啊 你框出来的时候就应该知道是因为编码的问题，你应该直接把这个被编码的原始url解码之后再拿来用的 jidesheng6 发表于 2020-2-13 19:39

对URL编码不太熟悉.... zx2000 发表于 2020-2-13 19:41

反正，这一类先解码了再来用，不然它里面又会编码一次
