我有一个测试URL，它返回一个 Json 结果如下
{"result":[{"Users":{"id":"1","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"2","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"3","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"4","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"5","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"6","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"7","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"8","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"9","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"10","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"11","user_name":"raj","user_password":"rajesh123"}},{"Users":{"id":"12","user_name":"raj","user_password":"rajesh123"}}],"error_code":1}
我的问题是当我在Chrome 浏览器上运行这个URL 时它返回正确的响应如上所述。但是邮递员的情况下它返回错误并显示以下消息
