[pheromone]

@dxjdqc
加上

dio.options.contentType =
ContentType.parse("application/x-www-form-urlencoded");

[dxjdqc]

@dxjdqc
加上

dio.options.contentType =
ContentType.parse（“application / x-www-form-urlencoded”）;
加了不管用啊

是url问题

我碰到的问题是因为　url前面没有https://

[xiaoai7904]

检查一下url地址是否带有 http:// 或者 https://
如果没有会导致出现这个报错
