我的自定义API设置为:
export default class API {
static send(verb, resource, raw_params, callback, errcallback) {
let org_id = window.localStorage._organization_id,
params = Object.keys(raw_params).reduce(function(o, k) {
o[k] = raw_params[k];
return o;
}, {});
errcallback = typeof errcallback === 'function' ? errcallback : function() {};
if (!!org_id && !params.hasOwnProperty('organization_id')) {
params.organization_id = org_id;
}
$.ajax({
url: URL + '/' + resource,
type: verb,
data: params
xhrFields: { withCredentials: true }
})
.done(callback)
.fail(errcallback);
}
static get(resource, params, callback, errcallback) {
API.send('GET', resource, params, callback, errcallback);
}
static post(resource, params, callback, errcallback) {
API.send('POST', resource, params, callback, errcallback);
}
static put(resource, params, callback, errcallback) {
API.send('PUT', resource, params, callback, errcallback);
}
static del(resource, params, callback, errcallback) {
API.send('DELETE', resource, params, callback, errcallback);
}
}
然后,我可以通过以下方式从应用程序中的任何文件发出API请求:
API.post('x/y', {params}, res => {
this.setState(res);
}, (xhr) => {
const errorMessage = JSON.parse(xhr.responseText).message;
alert('error', 5000, errorMessage);
}
我正尝试将其替换为axios
,并用以下内容替换了$.ajax
请求:
axios({
method: verb,
url: `${URL}/${resource}`,
data: params,
xhrFields: { withCredentials: true }
})
.then(callback)
.catch(errcallback)
但是它不会调用响应或错误回调。是否可以通过更新此类来处理该类,还是必须将每个请求替换为axios请求并使用定义的res
和xhr
的axios?
答案 0 :(得分:1)
Axios默认将数据发布为application/json
,而jQuery默认将其发布为application/x-www-form-urlencoded
。参见https://github.com/axios/axios#using-applicationx-www-form-urlencoded-format。
此外,虽然jQuery使用data
作为GET请求的查询参数,但Axios将请求正文有效负载和查询参数分别分为data
和params
属性。
请记住,要使用Axios替换jQuery,您需要执行以下操作...
const request = {
method: verb,
url: `${URL}/${resource}`,
withCredentials: true // are you sure you need this?
}
if (verb === 'GET' || verb === 'DELETE') {
request.params = params // query params, no request body
} else {
/// set appropriate request content-type
request.headers = { 'content-type': 'application/x-www-form-urlencoded' }
// convert "params" object into request body string
request.data = Object.entries(params).reduce((data, [key, value]) => {
data.append(key, value)
return data
}, new URLSearchParams())
}
axios(request).then(callback).catch(errcallback)
Object.entries(params).reduce(...)
只是从平面对象生成application/x-www-form-urlencoded
字符串的简化示例。 Axios本身建议使用qs library。
还要记住,Object.entries()
在任何版本的Internet Explorer中都不可用。
