It is a simple wrapper around node-http-proxy. By wrapping node-http-proxy, configurable-http-proxy extends this functionality to JupyterHub deployments. We recommend using the latest stable or LTS version of Node. When you start the proxy from the command line, you can set a default target --default-target option which will be used when no matching route is found in the proxy table:.

A JSON dictionary of the current routing table. This JSON dictionary excludes the default route. POST requests create new routes.

The body of the request should be a JSON dictionary with at least one key: targetthe target host to be proxied. Beginning with version 0. There are two typical errors that CHP may hit, along with their status code:. This can be prevented by setting a default target before starting the configurable-http-proxy. This is more common, and can be due to any number of reasons, including the target service having died or not finished starting.

When a proxy error occurs, CHP will look in the following location for a custom html error page to serve:.

OAuth 2.0: An Overview

If no custom error html file exists for the error code, CHP will use the error. If you specify an error path, make sure you also create an error.

If the CHP is started with the --host-routing option, the proxy will use the hostname of the incoming request to select a target. When using host-based routes, the API uses the target in the same way as if the hostname were the first part of the URL path, e. Skip to content.

HTTP proxy integration is a simple, powerful, and versatile mechanism to build an API that allows a web application to access multiple resources or features of the integrated HTTP endpoint, for example the entire website, with a streamlined setup of a single API method.

The request data that is passed through includes the request headers, query string parameters, URL path variables, and payload. The backend HTTP endpoint or the web server parses the incoming request data to determine the response that it returns.

The method exposes the entire set of the publicly accessible HTTP resources and operations of a website. When the backend web server opens more resources for public access, the client can use these new resources with the same API setup.

To enable this, the website developer must communicate clearly to the client developer what the new resources are and what operations are applicable for each of them. As a quick introduction, the following tutorial demonstrates the HTTP proxy integration. Next, do the following:. To create a child resource, choose a parent resource item under the Resources tree and then choose Create Resource from the Actions drop-down menu.

Then, do the following in the New Child Resource pane. Select the Configure as proxy resource option to create a proxy resource.

Otherwise, leave it de-selected. For this tutorial, select Configure as proxy resource. For Resource Nameuse the default, proxy. Choose the resource just created and then choose Create Method from the Actions drop-down menu. If the backend has made the corresponding backend endpoint available and, if so, has granted the required access permissions.

In addition, the client must be able to handle the output format of the backend in order to parse the result correctly. API Gateway does not mediate to facilitate interactions between the client and backend. If required, type a supported query expression for the chosen operation under the Query Strings heading. If required, type one or more supported header expressions for the chosen operation under the Headers heading.

If configured, set the required stage variable values for the chosen operation under the Stage Variables heading.People often serve the front-end React app from the same host and port as their backend implementation. Such setup is not required. To tell the development server to proxy any unknown requests to your API server in development, add a proxy field to your package. Conveniently, this avoids CORS issues and error messages like this in development:.

If the proxy option is not flexible enough for you, alternatively you can:. When you enable the proxy option, you opt into a more strict set of host checks. This is necessary because leaving the backend open to remote hosts makes your computer vulnerable to DNS rebinding attacks. The issue is explained in this article and this issue.

To work around it, you can specify your public development host in a file called. If you restart the development server now and load the app from the specified host, it should work. Note that this is dangerous and exposes your machine to remote code execution from malicious websites:.

If the proxy option is not flexible enough for you, you can get direct access to the Express app instance and hook up your own proxy middleware.

You can use this feature in conjunction with the proxy property in package. You can now register proxies as you wish! Here's an example using the above http-proxy-middleware :.

Note: You do not need to import this file anywhere. It is automatically registered when you start the development server. Note: This file only supports Node's JavaScript syntax. Be sure to only use supported language features i. Docs Help GitHub. Create React App. No 'Access-Control-Allow-Origin' header is present on the requested resource.

If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. It exposes your machine to attacks from the websites you visit. Edit this page.

The default target is used when a client has requested a URL for which there is no routing target found in the proxy table. To set a default targetpass the command line option, --default-targetwhen starting the configurable proxy:. A JSON dictionary of the current routing table. This JSON dictionary excludes the default route. POST requests create new routes.

The body of the request should be a JSON dictionary with at least one key: targetthe target host to be proxied. Custom error pages can be provided when the proxy encounters an error and has no proxy target to handle a request. There are two typical errors that CHP may hit, along with their status code:. This error can be prevented by setting a default target before starting the configurable-http-proxy.

This is more common, and can be due to any number of reasons, including the target service having died, not finished starting, or network instability.

Go back.An API is an interface that makes it easy for one application to 'consume' capabilities or data from another application.

By defining stable, simplified entry points to application logic and data, APIs enable developers to easily access and reuse application logic built by other developers. In the case of 'Web APIs', that logic and data is exposed over the network. The contract provides some level of assurance that, over time, the API will change in a predictable manner. Apigee Edge enables you to build APIs and if you have APIs already, expose them directly, while adding a management and visibility layer.

Edge also enables you to build APIs by implementing applications hosted on the API Services platform--with no backend service involved. You can build these applications in JavaScript, Java, and on Node. API proxies decouple the app-facing API from your backend services, shielding those apps from backend code changes.

As you make backend changes to your services, apps continue to call the same API without any interruption. Apigee provides several ways for you to create API proxies, including:.

Edge enables you to control API behavior without writing any code by using policies. Policies are designed to let you add common types of management capabilities to an API easily and reliably. Policies provide features like security, rate-limiting, transformation, and mediation capabilities, saving you from having to code and maintain this functionality on your own. Apigee provides a set of tutorials that you can use to create your first API.
