在 Jquery Ajax POST 中出现 400 个错误的请求错误 [英] Getting 400 bad request error in Jquery Ajax POST

问题描述

我正在尝试使用 Jquery 发送 Ajax POST 请求，但出现 400 个错误请求错误.

I am trying to send an Ajax POST request using Jquery but I am having 400 bad request error.

这是我的代码:

$.ajax({
  type: 'POST',
  url: "http://localhost:8080/project/server/rest/subjects",
  data: {
    "subject:title":"Test Name",
    "subject:description":"Creating test subject to check POST method API",
    "sub:tags": ["facebook:work", "facebook:likes"],
    "sampleSize" : 10,
    "values": ["science", "machine-learning"]
  },
  error: function(e) {
    console.log(e);
  }
});

它说:无法从请求构建资源.我错过了什么?

It Says: Can not build resource from request. What am I missing ?

推荐答案

最后，我犯了错误，原因是我需要对我发送的 JSON 数据进行字符串化.我必须在 XHR 对象中设置内容类型和数据类型.所以正确的版本在这里:

Finally, I got the mistake and the reason was I need to stringify the JSON data I was sending. I have to set the content type and datatype in XHR object. So the correct version is here:

$.ajax({
  type: 'POST',
  url: "http://localhost:8080/project/server/rest/subjects",
  data: JSON.stringify({
    "subject:title":"Test Name",
    "subject:description":"Creating test subject to check POST method API",
    "sub:tags": ["facebook:work", "facebook:likes"],
    "sampleSize" : 10,
    "values": ["science", "machine-learning"]
  }),
  error: function(e) {
    console.log(e);
  },
  dataType: "json",
  contentType: "application/json"
});

也许它会帮助别人.
