如何用循环生成的变量在Postman中批量发起删除ID请求？

Got it, let's fix this batch deletion issue. Since your server only allows deleting one ID per request, we can use Postman's pre-request and test scripts to loop through your target IDs and send individual requests for each one. Here's how to set it up:

Step 1: Configure the Pre-request Script #

First, we'll define our list of IDs to delete and initialize a counter to track progress. Paste this code into the Pre-request Script tab of your request:

// Store the array of IDs we need to delete in a global variable
pm.globals.set("deleteIds", JSON.stringify([1, 2]));
// Start with the first ID by setting an initial index of 0
pm.globals.set("currentIdIndex", 0);

Step 2: Add the Test Script to Loop Through Requests #

Next, we'll use the Test tab to send a deletion request for each ID, update our counter, and repeat until all IDs are processed. Add this code:

// Retrieve our stored ID list and current index from global variables
const deleteIds = JSON.parse(pm.globals.get("deleteIds"));
let currentIndex = parseInt(pm.globals.get("currentIdIndex"));

// Check if there are remaining IDs to process
if (currentIndex < deleteIds.length) {
    const targetId = deleteIds[currentIndex];
    // Build the full URL for the deletion request
    const requestUrl = `https://ids.com/${targetId}`;

    // Send the deletion request (adjust method/headers to match your server's requirements)
    pm.sendRequest({
        url: requestUrl,
        method: 'DELETE', // Switch to POST/PUT if your server uses a different deletion method
        header: {
            'Content-Type': 'application/json' // Add any required auth or custom headers here
        }
    }, function (err, res) {
        // Log results for debugging purposes
        console.log(`Processed ID ${targetId}: ${err ? 'Failed' : `Success (Status ${res.code})`}`);
    });

    // Update the index to point to the next ID
    currentIndex++;
    pm.globals.set("currentIdIndex", currentIndex);

    // Trigger the current request to run again for the next ID
    pm.execution.setNextRequest(pm.info.requestName);
} else {
    // Clean up global variables once all deletions are done
    pm.globals.unset("deleteIds");
    pm.globals.unset("currentIdIndex");
    console.log("All batch deletion requests completed successfully!");
}

How This Works #

• The pre-request script sets up our target ID list and starting point, so the test script knows exactly what to process.
• Every time the request runs, the test script checks if there are IDs left to delete. If yes, it sends a dedicated request for that specific ID.
• We increment our index and tell Postman to re-run the same request, repeating until every ID in our list is handled.
• Once all deletions are done, we clean up the global variables to avoid leftover data cluttering your environment.

Quick Notes #

• Adjust the method in pm.sendRequest to match what your server expects (e.g., POST if deletion uses that verb instead of DELETE).
• Add any required authentication headers (like API tokens) to the header object if your server requires them.
• Modify the deleteIds array in the pre-request script to include any IDs you need to batch delete in the future.
