Android Studio3 "Error:Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request""

Android Studio 3 显示如下错误信息：

Error:Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request"

原因：

AndroidStudio 没有找到 gradle 目录

解决办法：

File——Setting——Build,Execution,Deployment——Gradle——Use local gradle distribution——Gradle home：选择 android studio 安装目录下 Gradle 下相应版本的目录，OK。

Angular 2 http.post () 没有发送请求 - Angular 2 http.post () is not sending the request

问题：

When I make a post request the angular 2 http is not sending this request 当我发出帖子请求时，angular 2 http 没有发送此请求

this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions())

the http post is not sent to the server but if I make the request like this http post 不会发送到服务器，但如果我发出这样的请求

this.http.post(this.adminUsersControllerRoute, JSON.stringify(user), this.getRequestOptions()).subscribe(r=>{});

Is this intended and if it is can someone explain me why ? 这是有意的，如果是的话，有人可以解释我为什么吗？ Or it is a bug ? 或者它是一个错误？

解决方案：

AWS Secrets manager 和 setupProxy.js http-proxy-middleware

如何解决AWS Secrets manager 和 setupProxy.js http-proxy-middleware

在连接我的代理之前，我需要从机密管理器中提取配置

const express = require(''express'');
const { createProxyMiddleware } = require(''http-proxy-middleware'');
const { SecretsManagerClient,GetSecretValueCommand } = require(''@aws-sdk/client-secrets-manager'');
const pjson = require(''../app/config'');
const app = express();
async function getSecretsManager(){
    return secrets; // (this functions correctly,redacting for security)
}
const buildProxies = async (app) => {
    const proxies = pjson[''nonprod-proxies''];
    const secrets = await getSecretsManager();
    let proxiesToMap = [];
    proxies.forEach(proxy => {
        console.log(`[PROXY SERVER] Creating proxy for: ${proxy[''proxy-path'']}`);
        let target,headers,options;
        const rewrite = `^${proxy[''proxy-path'']}`;
        if (proxy[''internal''])
        {
            target = `https://${secrets[''apiDomain'']}`;
            headers = {''x-api-key'': secrets[''apiKey'']};
            options = {
                target: target,changeOrigin: true,logLevel: ''debug'',headers
            }
        } else {
            target = proxy[''proxy-domain''];
            options = {
                target: `https://${target}`,pathRewrite: {
                    [rewrite]: ''''
                }
            }
        }
        proxiesToMap.push({''path'': proxy[''proxy-path''],''options'': options})
    });
    return proxiesToMap;
};
module.exports = function(app){
    buildProxies().then(proxies => {
        proxies.forEach(proxyVal => {
            console.log(`Proxy: ${proxyVal[''path'']} with options ${proxyVal[''options'']}`);
            app.use(proxyVal[''path''],createProxyMiddleware(proxyVal[''options'']))
        });
    });
    console.log(''=== SUCCESSFULY CREATED PROXY SERVER ==='');
};

这会导致 localhost:3000 返回样板 html cors 响应，但是，当将 module.exports 的代码替换为：

app.use(''/internal/*'',createProxyMiddleware({
    target: ''<my aws secret url>'',headers: { ''x-api-key'': ''<my aws secret api key>'' }
}));

代理工作。有没有办法在 setupProxy.js 内异步加载配置？
