在我的本地开发环境中,我使用webpack devServer.proxy将API请求代理到https://.atlassian.net/rest/api/2,以抑制CORS问题。
但是请求超时
[HPM] Error occurred while trying to proxy request /project from localhost:9008 to https://<myProject>.atlassian.net/rest/api/2 (ETIMEDOUT) (https://nodejs.org/api/errors.html#errors_common_system_errors)
我想问题是,我位于代理后面的公司网络中,要访问Internet,我需要使用代理。代理设置包含在/ etc / profile(MacOS)中。
当我在相同的外壳中使用curl进行类似的请求时
curl --request GET --url 'https://<myProject>.atlassian.net/rest/api/2/project' --header 'Authorization: Basic <someBase64EncodedString>' --header 'Accept: application/json'
我得到一个有效的答案(我有权访问的所有项目的列表)。使用webpack-dev-server运行相同的请求时,超时(请参见上文)。
这是我的webpack devServer.proxy配置:
'/api/*': {
target: 'https://<myProject>.atlassian.net/rest/api/2',
headers: {
Authorization: 'Basic <someBase64EncodedString>',
Accept: "application/json"
},
secure: false,
changeOrigin: true,
pathRewrite: {
'^/api': ''
},
logLevel: 'debug'
}
任何想法为何webpack都会忽略/ etc / profile中的https_proxy?
有什么想法吗?
答案 0 :(得分:0)
由于我没有找到有关如何代理devServer.proxy的任何内容,因此我找到了一种解决方法:
我们需要使用另一个本地代理通过公司代理发送请求。这可以通过运行httpServer(localhost:9009)并获取请求(我想发送至https://myProject.atlassian.net/rest/api/2)的nodejs脚本来完成。然后,此httpServer会将我的请求发送到公司代理。 Webpack.devServer.proxy配置现在看起来像这样:
'/api/*': {
target: 'http://localhost:9009',
headers: {
Authorization: 'Basic <someBase64EncodedString>',
Accept: "application/json"
},
secure: false,
changeOrigin: true,
pathRewrite: {
'^/api': ''
},
logLevel: 'debug'
}
httpServer的“ postproxy.js”脚本如下所示:
var http = require('http');
var request = require('./node_modules/request');
var fs = require('fs');
var proxy = "<corporate proxy url>";
var api = "https://<myProject>.atlassian.net/rest/api/2/";
var hopper = "https://<myProject>.atlassian.net/rest/greenhopper/1.0";
http.createServer(function (reqorg, resorg) {
if (reqorg.method == 'POST'){
var bodyorg = '';
reqorg.on('data', function (data) {
bodyorg += data;
});
reqorg.on('end', function () {
var head = {
"content-type" : "application/json",
"Authorization": reqorg.headers.authorization
};
if(reqorg.url.includes("attachment")){
// Adjusting Head for Attachment Transfer
head["X-Atlassian-Token"] = "no-check";
head["content-type"] = "multipart/form-data";
var content = JSON.parse(bodyorg);
var buffer = Buffer.from(content.file,'base64');
var options = {
headers: head,
uri: api+reqorg.url,
formData: {
file: {
value: buffer,
options: {
filename: content.filename
}
}
},
method: 'POST'
}
request(options, function(err, response, body){
resorg.writeHead(200, {'Content-Type': 'application/json'});
resorg.end(body);
});
} else {
request.post({
headers: head,
url: api+reqorg.url,
proxy: proxy,
body: bodyorg
}, function(error, response, body){
resorg.writeHead(200, {'Content-Type': 'application/json'});
resorg.end(body);
});
}
});
} else if (reqorg.method == 'GET') {
request.get({
headers: {
'content-type' : 'application/json',
'Authorization': reqorg.headers.authorization
},
url: api + reqorg.url
}, function (error, response, body) {
resorg.writeHead(200, {'Content-Type': 'application/json'});
resorg.end(body);
})
} else if (reqorg.method == 'DELETE') {
request.delete({
headers: {
'content-type' : 'application/json',
'Authorization': reqorg.headers.authorization
},
url: api + reqorg.url
}, function (error, response, body) {
resorg.writeHead(200, {'Content-Type': 'application/json'});
resorg.end(body);
});
} else if (reqorg.method == 'PUT') {
var bodyorg = '';
reqorg.on('data', function (data) {
bodyorg += data;
});
reqorg.on('end', function () {
request.put({
headers: {
'content-type' : 'application/json',
'Authorization': reqorg.headers.authorization
},
url: hopper+reqorg.url,
proxy: proxy,
body: bodyorg
}, function(error, response, body){
resorg.writeHead(200, {'Content-Type': 'application/json'});
resorg.end(body);
});
});
}
}).listen(9009);
不要忘记在package.json中启动它:
"scripts": {
"start": "webpack-dev-server --mode development | npm run proxy",
"proxy": "node postproxy.js"
},
