JQuery Ajax 正在发送 GET 而不是 POST

JQuery Ajax is sending GET instead of POST

提问by Timothée HENRY

The following code triggers a GET instead of a POST HTTP request.

以下代码触发 GET 而不是 POST HTTP 请求。

function AddToDatabase() {
  this.url = './api/add';
}

AddToDatabase.prototype.postData = function(dataToPost) {
$.ajax({
    type: "POST",
    url: this.url,
    data: dataToPost,
    context: this,
    success: this.onSuccess
  });
};


var AddToDatabase = new AddToDatabase();
data = {data: 'coucou'};
AddToDatabase.postData(data);

Why, and how can I get a POST ?

为什么，以及如何获得 POST ？

I see in Google Chrome Inspect and Firefox Inspect that the browser sends a GET. Here is from Chrome:

我在 Google Chrome Inspect 和 Firefox Inspect 中看到浏览器发送了一个 GET。这是来自Chrome：

Request URL:http://localhost/SAMPLE-CODES/UPDATE%20MYSQL/api/add/ Request Method:GET Status Code:200 OK

请求地址：http://localhost/SAMPLE-CODES/UPDATE%20MYSQL/api/add/ 请求方法：GET 状态码：200 OK

SOLVED

解决了

The URL called './api/add' was to actually post to './api/add/index.php'. Turns out that calling './api/add/index.php' or './api/add/' gives me a POST request.

名为“./api/add”的 URL 实际上是发布到“./api/add/index.php”。原来调用 './api/add /index.php' 或 './api/add /' 给了我一个 POST 请求。

It was just a wrong URL, but for some reason I was getting a successful GET request to '.api/add/'.

这只是一个错误的 URL，但由于某种原因，我成功地收到了对“.api/add/”的 GET 请求。

Some problem on MVC. For some reason when I remove the [HttPost] it works as expected, even though I am telling ajax to use POST .

MVC 上的一些问题。出于某种原因，当我删除 [HttPost] 时，它按预期工作，即使我告诉 ajax 使用 POST 。

• It turns out you need to use

• 事实证明你需要使用

type: "POST"

类型：“POST”

• Even though the example on jQuery page says to use

• 即使 jQuery 页面上的示例说要使用

method : "POST"

方法：“POST”

Now it POST's

现在是 POST 的

But after digging in the documentation I found this.

但是在深入研究文档后，我发现了这一点。

I had this issue and per @FAngle's suggestion it was because my .htaccess was removing trailing slashes — and I had set the url to /ajax/foo/bar/and not/ajax/foo/bar. The redirect changes the request from POST to GET. Remove the / and problem solved!

我遇到了这个问题，根据@FAngle 的建议，这是因为我的 .htaccess 正在删除尾部斜杠 - 我已将 url 设置为/ajax/foo/bar/和 not /ajax/foo/bar。重定向将请求从 POST 更改为 GET。删除 / 并解决问题！

The URL './api/add'actually got redirected to './api/add/index.php'. therefore this bizarre side-affect which the new request after the redirect sent using GETinstead of POST

该 URL'./api/add'实际上被重定向到'./api/add/index.php'. 因此，这种奇怪的副作用是重定向后发送的新请求使用GET而不是POST

Solution

解决方案

• use the full url './api/add/index.php'
• or add a slash './api/add/'.

• 使用完整网址 './api/add/index.php'
• 或添加斜杠'./api/add/'。

I noticed this behavior as well where my POST was sending a GET. The scenario's pretty unique, but maybe it will help someone.

我在 POST 发送 GET 的地方也注意到了这种行为。这个场景非常独特，但也许它会对某人有所帮助。

This was happening to me on my User Role-edit page, where I was using ajax (post) as an immediate action when a role was checked or unchecked.

这是在我的用户角色编辑页面上发生在我身上，其中我在检查或未选中时使用Ajax（post）作为立即动作。

I also had the server configured to re-authenticate the user (and redirect them) whenever their role information changed so that their claims would be refreshed.

我还将服务器配置为在用户角色信息发生更改时重新验证用户（并重定向他们），以便刷新他们的声明。

The brutal cycle ended up as:

残酷的循环最终变成了：

1. First Role Update -- POST -- 200 success

2. Next Role Update -- POST -- 302 Found -> Redirect (I did not notice this until I used Fiddler rather than Chrome's network monitor)

3. Redirect Call from (2) (Same URL) -- GET -- 404 Not Found (since I only allowed Post)

4. GOTO (1)

1. 第一次角色更新 -- POST -- 200 成功

2. Next Role Update -- POST -- 302 Found -> Redirect （我没有注意到这一点，直到我使用 Fiddler 而不是 Chrome 的网络监视器）

3. 从 (2) (Same URL) 重定向调用 -- GET -- 404 Not Found（因为我只允许 Post）

4. 转到 (1)

I ended up changing the server to bypass re-authentication/claims update when it detected an ajax request (based on the Accept Types).

当检测到 ajax 请求（基于接受类型）时，我最终更改了服务器以绕过重新身份验证/声明更新。

I found that when using dataType: 'jsonp'it converts the request to a GET. I changed it to dataType: 'json'it changed from GETto POST.

我发现使用dataType: 'jsonp'它时会将请求转换为GET. 我把它改成它dataType: 'json'从GET变成POST。

I had a similar issue and it started working for me as soon as I removed the hardcoded https://from my url.

我有一个类似的问题，一旦我https://从我的 url 中删除了硬编码，它就开始为我工作。

jQuery.ajax({
 type: "POST",
 url: "www.someurl.com",//instead of "https://www.someurl.com"
 data: { foo:"bar"},
 success: function(d){ console.log(d); },
 dataType: "JSONP"
});

For me, your piece of code look OK, but if you want to be sure, you can use $.post instead of $.ajax

对我来说，你的代码看起来不错，但如果你想确定，你可以使用 $.post 而不是 $.ajax

$.post('ajax/test.html', function(data) {
 $('.result').html(data);
});

jquery link : http://api.jquery.com/jQuery.post/

jquery 链接：http: //api.jquery.com/jQuery.post/

Check out your .htaccess file or search for some other thing that may redirect your request

查看您的 .htaccess 文件或搜索其他可能重定向您的请求的内容

I had the same problem and found this question but answers didn't solve my problem. I eventually solve it by removing contentTypefield in ajax request.

我遇到了同样的问题并找到了这个问题，但答案并没有解决我的问题。我最终通过删除contentTypeajax 请求中的字段来解决它。

contentType: "application/json",

I had this issue, and it turned out to be a URL Rewrite module in IIS.

我遇到了这个问题，结果是 IIS 中的 URL 重写模块。

I'm using ASP.NET MVC and WebAPI. I created rule to force lowercase URLs so social networks don't view the same URL as two different pages.

我正在使用 ASP.NET MVC 和 WebAPI。我创建了强制使用小写 URL 的规则，这样社交网络就不会像两个不同的页面一样查看相同的 URL。

For example:

例如：

"http://url.com/View/Something/123GuidIdSomething"

“ http://url.com/View/Something/123GuidIdSomething”

vs

对比

"http://url.com/view/something/123guididsomething"

“ http://url.com/view/something/123guididsomething”

This however, was somehow messing with my ajax requests. I disabled the rule and the problem was resolved.

然而，这在某种程度上弄乱了我的 ajax 请求。我禁用了规则，问题就解决了。
