Spring数据REST无法将数据发布到REST api

Question

当我尝试使用以下命令将数据发布到我的REST API（使用Spring DATA JPA REST创建）时：

curl -g -i -X POST -H "Content-Type:application/json" -d '{  "profilphotoid" : 1  }'  http://localhost:8080/users/

我得到这个错误：

Answer 1

不要使用单引号，请使用双引号并转义内部双引号：

curl -g -i -X POST -H "Content-Type:application/json" -d "{ \"profilphotoid\" : 1 }" localhost:8080/users

注意：-g在本例中毫无用处。
