现在需要测试一个接口，通过抓包获取到了一个post请求，将其原封不动copy到postman中访问本地spring项目，出现MalformedJsonException: Unterminated string 报错。
org.springframework.http.converter.HttpMessageNotReadableException: Could not read JSON: com.google.gson.stream.MalformedJsonException: Unterminated string at line 8 column 14 path $.lat; nested exception is com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Unterminated string at line 8 column 14 path $.lat

在http headers中，有指定content-length，从json解析结果上看是content-length设置过小，猜测是不同的http发起者的版本或者字符集之类的不同导致content-length计算结果不同。
通过postman中取消对content-length的勾选完成接口的访问。应该是postman自动计算了相应的content-length，这里先不深究，如果有大佬知道欢迎评论。
