一、vue路由携带的参数,params与query

params:/router1/:id ,/router1/123,/router1/789 ,这里的id叫做paramsquery:/router1?id=123 ,/router1?id=456 ,这里的id叫做query。

通常配置的router的index.js,如果是一个详情页,那么个别路由变动只扭转一个id就好了,而后由id来对后盾发动网络申请,来申请不同详情的数据。

范例1:index.js配置动静路由,应用params形式:

比方我要写一个中国各个学校的详情页面,那么我要配置一个动静路由:

{    path:'/schoolDetail/:id',    name:'SchoolDetail',    component:schoolDetail,    meta:{      title:'SchoolDetail'    }  },

下面咱们只看path,前面的冒号示意id是一个变量,这个变量能够响应式变动,很合乎vue的特点。
当咱们应用语法跳转路由时(此时间接在地址下面加上你要跳转的id变量,就是params形式跳转):

this.$router.push({ path:'/testDetail/'+id)

浏览器是这个样子的:

前面一大串的数字是id号。

范例2:index.js不必配置动静路由,应用query形式实现路由动态变化:

咱们此时不必在index外面配置这个冒号id的话,其实在路由跳转配置也能够,那么来个例子:

{    path:'/schoolDetail',    name:'SchoolDetail',    component:schoolDetail,    meta:{      title:'SchoolDetail'    }  },

当咱们应用语法跳转路由时(间接定义个query的参数,此参数是一个对象,你能够往里面增加很多属性值,然而不要超过浏览器限度的长度就好了):

this.$router.push({ path:'/schoolDetail/', query:{id:id}})

搜寻框前面的id以问号宰割:

范例3:你也能够同时配置,只不过搜寻框的数字变多,且难看:

应用语法跳转路由(同时配置params及query参数):

this.$router.push({ path:'/schoolDetail/'+id, query:{_id:_id}})

浏览器搜寻框样子:

此时探索vue的params与query跳转路由试验完结,开始进行axios的参数携带:

二、axios发动申请的携带参数与后端解析时拿到的参数

1.get申请携带参数,应用params

 axios.request({    // method:"get",request    url:"/school/schools",    method:'get',   params:{    _id   }  })}

值得注意的是,axios的参数如同没有query的对象,只有params对象,这个是我刚开始的时候纳闷的,因为我用params能够正确传参,用query这个对象,发现传参不了。上面是我复制的文档的参数配置

{ // `url` is the server URL that will be used for the request url: '/user', // `method` is the request method to be used when making the request method: 'get', // default // `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. 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 or an instance of Buffer, ArrayBuffer, // FormData or Stream // You may modify the headers object. transformRequest: [function (data, headers) { // 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', 'POST', 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, Buffer 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, // default is `0` (no timeout) // `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 lib/adapters/README.md). 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 // `responseEncoding` indicates encoding to use for decoding responses // Note: Ignored for `responseType` of 'stream' or client-side requests responseEncoding: 'utf8', // 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 in bytes 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 // `socketPath` defines a UNIX Socket to be used in node.js. // e.g. '/var/run/docker.sock' to send requests to the docker daemon. // Only either `socketPath` or `proxy` can be specified. // If both are specified, `socketPath` is used. socketPath: null, // default // `httpAgent` and `httpsAgent` define a custom agent to be used when performing http // and https requests, respectively, in node.js. This allows options to be added 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. // You can also define your proxy using the conventional `http_proxy` and // `https_proxy` environment variables. If you are using environment variables // for your proxy configuration, you can also define a `no_proxy` environment // variable as a comma-separated list of domains that should not be proxied. // Use `false` to disable proxies, ignoring environment variables. // `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) { })}

附上文档地址,这个网站的文档可能不是最新的,然而足以解决你开发的应用了:axios文档

下面说了,axios如同没有query这个参数对象,那么就是说params外面携带的参数能够进行某种配置,让后端既能够应用params接管也能够通过query接管吗?
诚实说我不晓得,所以当我应用params携带我须要传递的信息时:

 axios.request({    // method:"get",request    url:"/school/schools",    method:'get',   params:{    _id   }  })}

发现后盾打印:

此时的params的参数为空,只有query参数能够看到,所以我感觉axios应用get申请的参数是只通过query查问。

2.post申请携带参数,应用data
axios的post申请的参数写在data外面,下面我复制的文档也写了,此时参数传给后盾时,是放在申请参数的body外面的,能够应用req.body获取:
范例:

axios.request({    // method:"get",request    url:"/login",    method:'post',    data:{      myStatus,//示意学生还是老师      username,      password    }  })}

后盾接管:
