ReactJS 获取发布 API 405 问题

Question

我正在使用 swagger 发布 APi，它工作正常，但是当我从 react jsm 发布它时会导致 405 问题。 Fiddler 为 swagger 显示 RAW 信息如下：

"test working"

对于来自反应的帖子如下：

我认为下面的 fetch post 功能有问题，有没有机会修复它，然后 RAW 信息可以与第一个相同。

onFormSubmit(Result) {
     fetch("http://localhost:7100/api/test/submit?guid=" +  "17327026-4348-4CE9-ACEB-5774C3A724BF",
      { 
        method: 'POST',
      // headers: {'Content-Type':'application/x-www-form-urlencoded'}, 
     headers: {'Content-Type':'application/json'}, 
   //     contentType: 'application/json; charset=utf-8',
      //  body: JSON.stringify(result) 
      body: "test working"
    })
      .then((response) => {
        console.log(response.ok ? 'success' : 'error');
      })
      .catch(function (error) {
        console.log('catch error');
      });
  }

这是一个CORS 问题您需要在您的服务器中允许来自http://localhost:3000 的请求。
