当我发送POST请求时,它没问题。但是当我发送一个PUT请求(将$ http.post()替换为$ http.put())时,Angular会发送一个没有数据的OPTIONS请求,等待响应并发送带有数据的PUT请求。
这不是CORPS问题,因为它是发送2个请求的客户端。
对于OPTIONS请求,JSON响应未被解析,因为Angular没有进入成功函数。
我想Angular不发送OPTIONS请求。 你知道这个问题吗?你知道修复吗?
代码:
var app = angular.module('myApp', []);
app.config(function($httpProvider) {
delete $httpProvider.defaults.headers.common['X-Requested-With'];
$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
$httpProvider.defaults.headers.put['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';
$httpProvider.defaults.useXDomain = true;
//
var param = function(obj) {
var query = '', 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;
};
// Override $http service's default transformRequest (json to application/x-www-form-urlencoded)
$httpProvider.defaults.transformRequest = [function(data) {
return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
}];
});
app.controller('login', function ($scope, $http) {
$scope.run = function() {
var file_data = $("#file").prop("files")[0];
var datas = {email:"email@domain.com", pass:sha1("xxxxxx")};
$http.put("http://myapi.com/user/connect", datas
).success(function(data, status, headers, config) {
console.log(data);
}).error(function(data, status, headers, config) {
});
return;
}
});

当您发起跨源请求时,浏览器始终使用OPTION方法发出飞行前请求。这意味着您尝试访问的API与您的应用程序的来源不同。你无能为力。
你知道这个问题吗?
您观察到的内容没有问题,这是预期的行为。
当我发送POST请求时,没关系。
Here's the reason why it's OK:
特别是,如果出现以下情况,请求会被预检:
- 它使用GET,HEAD或POST以外的方法。此外,如果使用POST来发送具有除以外的Content-Type的请求数据 application / x-www-form-urlencoded,multipart / form-data或text / plain, 例如如果POST请求使用XML向服务器发送XML有效负载 application / xml或text / xml,然后请求预检。
- 在请求中设置自定义标头(例如,请求使用标头,例如X-PINGOTHER)
