英文:
Cannot get Angular/Restangular form data in Go
问题
我有一个正常工作的Go REST服务，我可以使用Chrome REST插件获取表单数据。
我需要从我的Angular应用程序获取表单数据到服务端，到目前为止我还无法弄清楚。
我的Angular代码：
<form name="myForm">
<div class="control-group" ng-class="{error: myForm.name.$invalid}">
<label>Drug Name</label>
<input type="text" name="drugName" ng-model="drug.name" required>
<span ng-show="myForm.drugName.$error" class="help-inline">
Required</span>
</div>
<a href="#/" class="btn">Cancel</a>
<button ng-click="save()" ng-disabled="isClean() || myForm.$invalid"
class="btn btn-primary">Save</button>
<button ng-click="destroy()" ng-show="project._id"
class="btn btn-danger">Delete</button>
</form>
我的app.js中的CreateCtrl，我设置了 RestangularProvider.setBaseUrl('/rest/v1');：
function CreateCtrl($scope, $location, Restangular) {
$scope.save = function() {
Restangular.all('drugs/').post($scope.drug).then(function(project) {
$location.path('/list');
});
}
}
在我的Go代码中，我使用gorilla，以下是相关部分：
http.Handle("/rest/v1/drugs/", drugs.MakeMuxer("/rest/v1/drugs/"))
func MakeMuxer(prefix string) http.Handler {
log.Println("**** drugs.MakeMuxer(): " + prefix);
var m *mux.Router
// 如果有前缀，则传递前缀。
if prefix == "" {
m = mux.NewRouter()
} else {
m = mux.NewRouter().PathPrefix(prefix).Subrouter()
}
m.HandleFunc("/", CreateDrug).Methods("POST")
// 其他所有请求都应该返回404。
//m.HandleFunc("/{path:.*}", gorca.NotFoundFunc)
return m
}
func CreateDrug(w http.ResponseWriter, r *http.Request) {
log.Println("**** CreateDrug.... ");
log.Println("drugName: " + r.FormValue("drugName"))
//c := appengine.NewContext(r)
}
我可以看到POST请求进入了"CreateDrug"函数，但是r.FormValue("drugName")是空的（当我使用浏览器的REST插件并将"drugName"设置为某个值时，它不为空）。

I have a Go rest service that works fine, I can get form data using a Chrome REST plugin.
I need to get form data from my Angular app to the service, and so far I cannot figure it out.
My Angular code:
<form name="myForm">
<div class="control-group" ng-class="{error: myForm.name.$invalid}">
<label>Drug Name</label>
<input type="text" name="drugName" ng-model="drug.name" required>
<span ng-show="myForm.drugName.$error" class="help-inline">
Required</span>
</div>
<a href="#/" class="btn">Cancel</a>
<button ng-click="save()" ng-disabled="isClean() || myForm.$invalid"
class="btn btn-primary">Save</button>
<button ng-click="destroy()" ng-show="project._id"
class="btn btn-danger">Delete</button>
</form>
My app.js CreateCtrl, I set RestangularProvider.setBaseUrl('/rest/v1');:
function CreateCtrl($scope, $location, Restangular) {
$scope.save = function() {
Restangular.all('drugs/').post($scope.drug).then(function(project) {
$location.path('/list');
});
}
}
In my Go code, I am using gorilla, and here are the pertinent parts:
http.Handle("/rest/v1/drugs/", drugs.MakeMuxer("/rest/v1/drugs/"));
func MakeMuxer(prefix string) http.Handler {
log.Println("**** drugs.MakeMuxer(): " + prefix);
var m *mux.Router
// Pass through the prefix if we have one.
if prefix == "" {
m = mux.NewRouter()
} else {
m = mux.NewRouter().PathPrefix(prefix).Subrouter()
}
m.HandleFunc("/", CreateDrug).Methods("POST")
// Everything else should 404.
//m.HandleFunc("/{path:.*}", gorca.NotFoundFunc)
return m
}
func CreateDrug(w http.ResponseWriter, r *http.Request) {
log.Println("**** CreateDrug.... ");
log.Println("drugName: " + r.FormValue("drugName"))
//c := appengine.NewContext(r)
}
I can see that the POST is getting into "CreateDrug", but r.FormValue("drugName") is empty (it is not empty when I use a browser rest plugin and set "drugName" to some value.

在调用r.FormValue之前，你需要调用r.ParseForm()。
//编辑
在查阅了AngularJS之后，我注意到它将数据发送为JSON格式，所以你需要使用json.NewDecoder，示例：
type Drug struct {
Name string `json:"drugName"`
}
func CreateDrug(w http.ResponseWriter, r *http.Request) {
defer r.Body.Close()
var d Drug
dec := json.NewDecoder(r.Body)
dec.Decode(&d)
log.Println("**** CreateDrug.... ")
log.Println("drugName:", d.Name)
}
英文:
You need to call r.ParseForm() before you can call r.FormValue.
//edit
After looking up angularjs, I noticed it sends the data as json, so you have to use json.NewDecoder, example:
type Drug struct {
Name string `json:"drugName"`
}
func CreateDrug(w http.ResponseWriter, r *http.Request) {
defer r.Body.Close()
var d Drug
dec := json.NewDecoder(r.Body)
dec.Decode(&d)
log.Println("**** CreateDrug.... ")
log.Println("drugName:", d.Name)
}
