http的get请求中的url中添加Object参数
一直以来http的get请求中，都没有尝试带过复杂对象参数，最新在写grpc时， 使用了框架自动转化rpc请求到http请求，参数定义时没有注意复杂度，定义了个对象嵌套对象的请求参数，所以尝试了下载请求的url中携带对象参数的方案。
先说解决方案， 把对象序列化成字符串，encode然后加到url中即可。 请参考下面的sample：
- server端定义的请求参数对象
type HelloRequest struct {
Id int32
Name string
User *User
}
type User struct {
Id int32
Name string
}
- 前端发送请求
var helloRequest = {"id": 2,"name": "User",}
var helloRequestString = encodeURI(JSON.stringify(helloRequest))
var url = 'http://localhost:8080/v2/hello?id=1&name=hello&user=' + helloRequestString
var ajaxObj = new XMLHttpRequest();
ajaxObj.open('get', url);
ajaxObj.send();
只需要把第一层里面嵌套的对象序列化即可
