设置"enctype"& quot; application/json& quot;属性 [英] Set "enctype" attribute to "application/json"

问题描述

这是我发出POST请求的代码:

Here is my code for making POST request:

function post(path, params, method) {
  method = method || "post"; // Set method to post by default if not specified.

  // The rest of this code assumes you are not using a library.
  // It can be made less wordy if you use one.
  var form = document.createElement("form");
  form.setAttribute("method", method);
  form.setAttribute("action", path);
  form.setAttribute("enctype", "application/json");
  for(var key in params) {
    if(params.hasOwnProperty(key)) {
      var hiddenField = document.createElement("input");
      hiddenField.setAttribute("type", "hidden");
      hiddenField.setAttribute("name", key);
      hiddenField.setAttribute("value", params[key]);

      form.appendChild(hiddenField);
    }
  }

  document.body.appendChild(form);
  form.submit();
}

我试图通过将表单的 enctype 设置为"application/json"，将HTTP标头中的 Content-type 设置为"application/json".但是，它不起作用.

I tried to set the Content-type in HTTP header to "application/json" by setting enctype of the form to "application/json". However, it doesn't work.

我看到了非正式草案关于支持"application/json"> enctype ，但似乎尚未接受..

I saw an unofficial draft about supporting "application/json" for enctype however it seems not accepted yet..

有人有没有关于如何发出POST请求并使用 JSON 而不是 formdata 作为数据格式的想法，而不求助于AJAX?

Does anyone have ideas about how to make a POST request and use JSON instead of formdata as the data format without resorting to AJAX?

在当前的浏览器中无法做到这一点.

There is no way to do this in current browsers.

如果您编写的HTTP端点需要正常的表单提交，请编写它，使其接受 application/x-www-form-urlencoded 和 multipart/form-data 编码数据.

If you are writing an HTTP endpoint that expects normal form submissions, write it so it accepts application/x-www-form-urlencoded and multipart/form-data encoded data.
