CodeIgniter中Sabre Enhance Air机票接口返回错误结果求助

Let's walk through the most likely issues causing your Sabre Enhance Air ticket request to fail in CodeIgniter, using the details you shared:

1. Truncated/Malformed Request Body #

Your $postData cuts off mid-way at "Suppress": true,... — this is a huge red flag. Sabre's API requires a valid, fully complete JSON payload for the AirTicketRQ endpoint. Even a missing bracket, incomplete field, or typo here will trigger a validation error immediately.

• Double-check that your full JSON matches Sabre's official AirTicketRQ specification. Make sure all required fields are present (like finishing the CC_Info object if you're using a credit card, or including all mandatory ticketing parameters).
• Run your payload through a local JSON validator (most IDEs have built-in tools for this) to catch syntax errors before sending the request.

2. Unnecessary/Incorrect Request Headers #

Looking at your $headers2 array:

• The protocol: HTTP 1.1 header is non-standard and Sabre's API doesn't require it. This could cause unexpected parsing issues — remove it entirely.
• Verify that your $access_token is valid and hasn't expired. Sabre's access tokens typically last only 30 minutes, so if you generated it a while ago, that's probably the issue. Test the token with a simple sandbox endpoint to confirm it works.
• Ensure the Content-Type: application/json header has no extra spaces (yours looks okay, but it's worth double-checking) — this tells the API you're sending JSON, which is mandatory for this endpoint.

3. Invalid Itinerary ID #

Your request references itinerary ID "VWKJJT":

• Confirm this itinerary is still active and hasn't been expired, canceled, or already ticketed. Sabre itineraries usually have a 24-48 hour validity window depending on the fare rules.
• Make sure the itinerary was created using the same credentials/access token as your ticketing request. Cross-referencing itineraries from different sessions or accounts will fail.

4. Misconfigured FOP_Qualifiers #

Your FOP_Qualifiers section uses MultipleFOP with a fare amount of "100.00":

• Ensure this amount exactly matches the total fare of the itinerary "VWKJJT". Even a cent difference will trigger an error.
• If you're using Suppress: true for CC_Info, confirm this is allowed under your Sabre contract. Some accounts require explicit payment details unless you're using a stored profile or alternative form of payment.

5. CodeIgniter Request Handling Quirks #

CodeIgniter's HTTP tools (whether you're using raw curl or the framework's CURLRequest class) might be altering your request without you noticing:

• If using curl, make sure you're passing the raw JSON string to CURLOPT_POSTFIELDS, not an array. Passing an array will encode the data as form-data, which doesn't match your Content-Type header.
• Add logging to capture the full request (headers + body) right before sending it. Compare this to a working request from Sabre's test tools to spot any discrepancies.

6. Capture and Analyze Sabre's Error Response #

The biggest help will be looking at the full error response from Sabre. The API almost always returns a JSON object with specific error codes and messages that tell you exactly what's wrong (e.g., invalid itinerary, missing field, authorization failure).

• In CodeIgniter, after running your curl request, use curl_getinfo() and curl_error() to fetch response details. If using the framework's HTTP client, use the getBody() method to retrieve the error data.
