首先排除请求体中 json 格式问题 如：、[]、()、""、''等缺少部分不对称问题，

如格式没有问题，再看 Content-Length，如果body中的长度大于Content-Length将会截取body导致json格式异常；如果body中的长度小于Content-Length将会导致请求超时，最好不要设置Content-Length。

如果上边两个情况都不是（我的就是这样），可能是 json 内容问题，我的就是复制的微信发送过来的 json 内容，在postman上测试，就报这个错，微信好像对空格的编码不一样，导致服务端对 json 内容转换对象不成功。把 json 内容里所有的空格用 ide 工具的空格全部替换掉就可以了。
