Vue.js教程之axios与网络传输的学习实践

// Optionally the request above could also be done as
axios.get('/user',{
params: {
ID: 12345
}
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});

function getUserPermissions() {
return axios.get('/user/12345/permissions');
}

axios.all([getUserAccount(),getUserPermissions()])
.then(axios.spread(function (acct,perms) {
// Both requests are now complete
}));

// baseURL will be prepended to url unless url is absolute.
// It can be convenient to set baseURL for an instance of axios to pass relative URLs
// to methods of that instance.
// 假如url不是绝对路径，那么向服务器发送请求的URL将是baseURL + url
baseURL: 'https://some-domain.com/api/',// transformRequest allows changes to the request data before it is sent to the server
// This is only applicable for request methods 'PUT','POST',and 'PATCH'
// The last function in the array must return a string,an ArrayBuffer,or a Stream
transformRequest: [function (data) {
// Do whatever you want to transform the data

return data;
}],// transformResponse allows changes to the response data to be made before
// it is passed to then/catch
transformResponse: [function (data) {
// Do whatever you want to transform the data

return data;
}],// headers are custom headers to be sent
headers: {'X-Requested-With': 'XMLHttpRequest'},// params are the URL parameters to be sent with the request
// Must be a plain object or a URLSearchParams object
params: {
ID: 12345
},// paramsSerializer is an optional function in charge of serializing params
// (e.g. https://www.npmjs.com/package/qs,http://api.jquery.com/jquery.param/)
paramsSerializer: function(params) {
return Qs.stringify(params,{arrayFormat: 'brackets'})
},// data is the data to be sent as the request body
// Only applicable for request methods 'PUT',and 'PATCH'
// When no transformRequest is set,must be of one of the following types:
// - string,plain object,ArrayBuffer,ArrayBufferView,URLSearchParams
// - Browser only: FormData,File,Blob
// - Node only: Stream
data: {
firstName: 'Fred'
},// timeout specifies the number of milliseconds before the request times out.
// If the request takes longer than timeout,the request will be aborted.
timeout: 1000,// withCredentials indicates whether or not cross-site Access-Control requests
// should be made using credentials
withCredentials: false,// default

// adapter allows custom handling of requests which makes testing easier.
// Return a promise and supply a valid response (see response docs).
adapter: function (config) {
/ ... /
},// auth indicates that HTTP Basic auth should be used,and supplies credentials.
// This will set an Authorization header,overwriting any existing
// Authorization custom headers you have set using headers.
auth: {
username: 'janedoe',password: 's00pers3cret'
},// responseType indicates the type of data that the server will respond with
// options are 'arraybuffer','blob','document','json','text','stream'
responseType: 'json',// default

// xsrfCookieName is the name of the cookie to use as a value for xsrf token
xsrfCookieName: 'XSRF-TOKEN',// default

// xsrfHeaderName is the name of the http header that carries the xsrf token value
xsrfHeaderName: 'X-XSRF-TOKEN',// default

// onUploadProgress allows handling of progress events for uploads
onUploadProgress: function (progressEvent) {
// Do whatever you want with the native progress event
},// onDownloadProgress allows handling of progress events for downloads
onDownloadProgress: function (progressEvent) {
// Do whatever you want with the native progress event
},// maxContentLength defines the max size of the http response content allowed
maxContentLength: 2000,// validateStatus defines whether to resolve or reject the promise for a given
// HTTP response status code. If validateStatus returns true (or is set to null
// or undefined),the promise will be resolved; otherwise,the promise will be
// rejected.
validateStatus: function (status) {
return status >= 200 && status < 300; // default
},// maxRedirects defines the maximum number of redirects to follow in node.js.
// If set to 0,no redirects will be followed.
maxRedirects: 5,// default

// httpAgent and httpsAgent define a custom agent to be used when performing http
// and https requests,respectively,in node.js. This allows to configure options like
// keepAlive that are not enabled by default.
httpAgent: new http.Agent({ keepAlive: true }),httpsAgent: new https.Agent({ keepAlive: true }),// 'proxy' defines the hostname and port of the proxy server
// auth indicates that HTTP Basic auth should be used to connect to the proxy,and supplies credentials.
// This will set an Proxy-Authorization header,overwriting any existing Proxy-Authorization custom headers you have set using headers.
proxy: {
host: '127.0.0.1',port: 9000,auth: : {
username: 'mikeymike',password: 'rapunz3l'
}
},// cancelToken specifies a cancel token that can be used to cancel the request
// (see Cancellation section below for details)
cancelToken: new CancelToken(function (cancel) {
})
