无法从localhost执行跨域REST API调用[重复]

jira-rest-api reactjs javascript

ParthPatel · 技术社区 · 7 年前

我正在尝试使用JIRA在REACT中提供的RESTAPI进行登录。但我犯了这样的错误

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. 
Origin 'http://localhost:8085' is therefore not allowed access. The response had HTTP status code 403. 
If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

下面是我的代码,我正在测试它以进行登录。

fetch("https://jira.company.com/rest/auth/latest/session",{
  method:'POST',
  headers: {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin" : "*"
  },
  body: 
    JSON.stringify({
    username:"username",
    password : "password"})
  }).then(result => console.log(result));

我也尝试了以下参数,但结果是相同的错误。

'Access-Control-Allow-Origin' : '*',
'Access-Control-Allow-Methods': 'POST, GET, OPTIONS',

我还查阅了 JIRA API 但找不到任何可用于跨域请求访问的内容。正在寻找跨域执行API调用的帮助。

按设置尝试 mode: 'cors'

fetch("https://jira.company.com/rest/auth/latest/session", {
  method: 'POST',
  headers: {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "*"
  },
  mode: 'cors',
  body: JSON.stringify({
    username: "username",
    password: "password"
  })
}).then(function(resp) {
  return resp.json();

}).then(function(data) {
  console.log(data)
});

注意:在演示中,您可能会看到 404 这意味着找不到,因为它没有发送用户名&暗语
