Question

我们使用$ http.post向我们的服务器发送请求，当服务器没有及时回复（大约3秒）时，我们的angularjs客户端发送另一个http.post。我们用tcpdump跟踪了这个，我们看到了2个不同的$ http.post。

这是我们的控制器：

var request = Local.testPost();
request.then(function successCallback(response) {
  console.log(response);
}, function errorCallback(error) {
   console.log(error);
});

这是我们的本地服务帖子：

this.testPost = function(){
    var data = 'token='+User.getToken();

    var request = $http(
        {
            method: 'post',
            headers: {
               'Content-Type': 'application/x-www-form-urlencoded'
             },
            url: self.server+'/api/cmd',
            data: data
        }
    );
    return request;
};

我们的服务器也记录了2个不同的帖子......

怎么可能？谢谢大家！

一个可能的原因可能是您的服务器响应408状态，在这种情况下，某些重试会自动运行。如果408不是“真实”408，则不应回复//Function to change case function upperCaseValue(element) { //Test that passed element has a "value" field if( typeof element.value !== void 0) { //Overwrite value element.value = element.value.toUpperCase(); } } //Fetch elements to watch var search = document.getElementById("search"); var output = document.getElementById("output"); //Bind events search.addEventListener("keyup", function(){ //Change case upperCaseValue(search); //Use input output.innerHTML = search.value; }); search.addEventListener("change", function(){ //Change case upperCaseValue(search); //Use input output.innerHTML = search.value; });。
