试图在rest api上修补数组

Question

我无法成功将值推送到作为rest api上对象一部分的数组。我正在关注Patching arrays，但我无法让它发挥作用。

const xhr = new XMLHttpRequest();

const formData = { "op": "add", "path": "/residents", "value": this.state.person.id };
console.log(formData)

xhr.open('PATCH', 'http://localhost:3008/planets/' + this.state.person.planetID);

xhr.setRequestHeader('Content-type', 'application/json');

xhr.responseType = 'json';

xhr.addEventListener('load', () => { 

    //patch the person const planet id 

});
xhr.send(formData);

Answer 1

如json补丁的RFC Doc中所述，您需要附加＆＃39; - ＆＃39;走到路上：

const formData = { "op": "add", "path": "/residents/-", "value": this.state.person.id };

或指定一个显式索引，您希望将值添加到数组中。
