It's a convenient way to directly set a local file to a Body by using
bodyFilePath property// For request
request.bodyFilePath = "~/Desktop/image.png";
// For response
response.bodyFilePath = "~/Desktop/image.png";
function onResponse(context, url, request, response) {
response.headers["Content-Type"] = "image/png";
response.bodyFilePath = "~/Desktop/image.png";
// Done
return response;
}
function onResponse(context, url, request, response) {
response.headers["Content-Type"] = "application/json";
response.bodyFilePath = "~/Desktop/my_response.json";
// Done
return response;
}
It's possible to use your JSON file and set it as a Request/Response's body
You can use set a different body for each matching endpoint by using the IF statement.
- 1.
- 2.Set Script Rule with wildcard or Regex pattern that can match many endpoints. E.g https://my-domain.com/v*
- 3.Use `includes()` to check whether or not the endpoint is matched
const file_1 = require("@users/myfile_1.json");
const file_2 = require("@users/myfile_2.json");
const file_3 = require("@users/myfile_3.json");
function onResponse(context, url, request, response) {
// Set JSON content
response.headers["Content-Type"] = "application/json";
// Check
if (url.includes("v1/data")) {
response.body = file_1
} else if (url.includes("v2/login")) {
response.body = file_2
} else if (url.includes("v3/user")) {
response.body = file_3
}
// Done
return response;
}
// Import your JSON file here
const file = require("@users/B02D96D5.default_message_32E64A5B.json");
function onRequest(context, url, request) {
// 1. Extract the queryName from the request
var queryName = request.body.query.match(/\S+/gi)[1].split('(').shift();
// 2. Save to sharedState
sharedState.queryName = queryName
// Done
return request;
}
function onResponse(context, url, request, response) {
// 3. Check if it's the request we need to map
if (sharedState.queryName == "user") {
// 4. Import the local file by Action Button -> Import
// Get the local JSON file and set it as a body (like Map Local)
response.headers["Content-Type"] = "application/json";
response.body = file;
}
// Done
return response;
}
Since Javascript doesn't have the Data object type, the Data Body will convert to Base64 Encoded String in Javascript. To pass Uint8Array, blob, or ArrayBuffer to the body, make sure you convert to Base64 Encoded String and set the ContentType to
application/octet-streamProxyman will convert Base64 Encoding to ArrayBuffer, so the client will receive the data properly.
// Import
const { btoa } = require('@addons/Base64.js');
function onResponse(context, url, request, response) {
// Construct the ArrayBuffer
const buffer = new ArrayBuffer(256)
const view = new Uint8Array(buffer)
for (let i = 0; i < view.length; i++) {
view[i] = i
}
// Convert ArrayBuffer to Base64String
var newBody = btoa(String.fromCharCode.apply(null, new Uint8Array(buffer)));
// Set new body
response.body = newBody;
response.statusCode = 200
response.headers['Content-Type'] = 'application/octet-stream'
// Done
return response;
}
function onRequest(context, url, request) {
request.preserveHostHeader = true
return request
}
Use
comment or color to highlight on the main table view.function onRequest(context, url, request) {
request.comment = "It's a Request"
request.color = "red" // red, blue, yellow, purple, gray, green
return request
}
function onResponse(context, url, request, response) {
response.comment = "It's a Response"
response.color = "yellow" // red, blue, yellow, purple, gray, green
return response
}
Use Scripting for Color and Comment
- 1.Prepare a JSON file and save it to your Desktop
// myfile.json
{
"name": "Proxyman",
"platform": "macOS",
"info": {
"website": "proxyman.io",
"region": "Earth"
}
}
2. More -> Import JSON or Other Files. Then selecting your file
3. Proxyman will add the import code to the top of the script
// ~/Library/Application Support/com.proxyman.NSProxy/users/myfile.json
const file = require("@users/myfile.json");
function onResponse(context, url, request, response) {
// 1. Set header to JSON if need
response.headers["Content-Type"] = "application/json";
// 2. Set Body as a imported file
response.body = file;
return response;
}
The selected file is copied to ~/Library/Application\ Support/com.proxyman.NSProxy/users folder.
To support other format files, such as image, text, pdf. Make sure you have correct Header Content-Type
- 1.Follow the same above instruction (Select your Binary File)
- 2.Set it as a body
// ~/Library/Application Support/com.proxyman.NSProxy/users/myscreenshot.png
const file = require("@users/myscreenshot.png");
function onResponse(context, url, request, response) {
// Set header
response.headers["Content-Type"] = "image/png";
// Set Body
response.body = file;
return response;
}
- 1.Follow the same above instruction (Select your Binary File)
- 2.Set it as a body
// ~/Library/Application Support/com.proxyman.NSProxy/users/main.css
const file = require("@users/main.css");
function onResponse(context, url, request, response) {
// Set header
response.headers["Content-Type"] = "text/css";
// Set Body
response.body = file;
return response;
}
From Proxyman 2.24.0+, you can import any files without using the "Import File".
// Import your file from your Desktop folder
const file = require("~/Desktop/myfile.json");
function onResponse(context, url, request, response) {
// 1. Set header to JSON if need
response.headers["Content-Type"] = "application/json";
// 2. Set Body as a imported file
response.body = file;
return response;
}
- If the file has ".js" as an extension => Proxyman will execute it as a JS Script
- Otherwise, Proxyman will import it as normal
Only files that are imported by using the "Import Tool", are included when exporting the script to your colleague.
