OKHttp3 post方法总是返回404错误
问题描述:
我想用OKHttp3做POST,但它一直返回404。我的代码有什么问题吗?服务器端不断告诉我,url和json是正确的。OKHttp3 post方法总是返回404错误
我曾尝试另一篇文章的URL和JSON,它的工作原理,返回码200

我看到你有一些测试电话。如果您正在测试API,则可以使用Postman之类的内容:https://chrome.google.com/webstore/detail/postman/fhbjgbiflinjbdggehcddcbncdddomop – Gudin
。如果我早些时候尝试邮递员,所有这些麻烦都可以保存下来。 –
