这是我后台SpringMVC控制器接收isform参数的方法,只是简单的打出它的值:
12345678 | @RequestMapping (method = RequestMethod.POST) @ResponseBody public
@RequestParam (value = "isform" , required = false ) String isform) { System.out.println( "isform value: " + isform); return
; } |
发现后台没有取到值
后边我想到的第一种方案是在控制器方法参数里加requestbody来接收json参数,改成如下:
12345678 | @RequestMapping (method = RequestMethod.POST) @ResponseBody public
@RequestParam (value = "isform" , required = false ) @RequestBody
System.out.println( "isform value: " + isform); return
; } |
接着我又对比了下以前的项目中,接收post请求的参数,发现一个有趣的现象,
下边是Angular的默认请求头,
$httpProvider.defaults.headers.post: (header defaults for POST requests)
Content-Type: application/json
$httpProvider.defaults.headers.put(header defaults for PUT requests)
Content-Type: application/json
其中Angular的post和put都是application/json,
而jquery的post请求的"Content-Type"默认为" application/x-www-form-urlencoded ",于是我更改了angular的默认Content-Type,12345 | app.config( function ($httpProvider) { $httpProvider.defaults.headers.put[ 'Content-Type' ] = 'application/x-www-form-urlencoded' ; $httpProvider.defaults.headers.post[ 'Content-Type' ] = 'application/x-www-form-urlencoded' ; }); |
又查了半天,在一个老外的博客上发现了原因,链接如下:
http://victorblog.com/2012/12/20/make-angularjs-http-service-behave-like-jquery-ajax/
By default, jQuery transmits data using Content-Type: x-www-form-urlencoded and the familiar foo=bar&baz=moe serialization. AngularJS, however, transmits data using Content-Type: application/json and { "foo": "bar", "baz": "moe" } JSON serialization
自己翻译了:
默认情况下,jQuery传输数据使用Content-Type: x-www-form-urlencodedand和类似于"foo=bar&baz=moe"的序列,然而AngularJS,传输数据使用Content-Type: application/json和{ "foo": "bar", "baz": "moe" }这样的json序列。
所以下把Content-Type设置成x-www-form-urlencodedand之后,还需要转换序列的格式,
下边是我经过老外实践而自己测试过的最终方案:
123456789101112131415161718192021222324252627282930313233343536373839404142434445464748 | app.config( function ($httpProvider) { $httpProvider.defaults.headers.put[ 'Content-Type' ] = 'application/x-www-form-urlencoded' ; $httpProvider.defaults.headers.post[ 'Content-Type' ] = 'application/x-www-form-urlencoded' ; // Override $http service's default transformRequest $httpProvider.defaults.transformRequest = [ function (data) { /** * The workhorse; converts an object to x-www-form-urlencoded serialization. * @param {Object} obj * @return {String} */ var
function (obj) { var
'; var name, value, fullSubName, subName, subValue, innerObj, i; for (name in obj) { value = obj[name]; if (value instanceof Array) { for (i = 0; i < value.length; ++i) { subValue = value[i]; fullSubName = name + ' [ ' + i + ' ] '; innerObj = {}; innerObj[fullSubName] = subValue; query += param(innerObj) + ' & '; } } else if (value instanceof Object) { for (subName in value) { subValue = value[subName]; fullSubName = name + ' [ ' + subName + ' ] '; innerObj = {}; innerObj[fullSubName] = subValue; query += param(innerObj) + ' & '; } } else if (value !== undefined && value !== null) { query += encodeURIComponent(name) + ' = ' + encodeURIComponent(value) + ' & '; } } return query.length ? query.substr(0, query.length - 1) : query; }; return angular.isObject(data) && String(data) !== ' [object File]' ? param(data) : data; }]; }); |
发现与jquery的post请求风格一致了,有木有!!!
看下后台的参数接收情况,
isform已经可以正常接收到参数了,大功告成!
