vue resource post请求时遇到的坑

// global Vue object
Vue.http.get('/someUrl', [options]).then(suessCallback, errorCallback);
Vue.http.post('/someUrl', [body], [options]).then(suessCallback, errorCallback);
// in a Vue instance
this.$http.get('/someUrl', [options]).then(suessCallback, errorCallback);
this.$http.post('/someUrl', [body], [options]).then(suessCallback, errorCallback);

http: {
  headers: {'Content-Type': 'application/x--form-urlencoded'}
}

Vue.http.options.emulateJSON = true;
