Sage sdata Web服务问题

Question

I am working on Sage SData integration. Unfortunately, there is a problem in sending data to the server. I am able to retrieve data and delete contract but when I add new contract through POST or update through PUT , it gives an error:

error ApplicationDiagnosis Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection

Does any one have a PHP or JSON example of adding a new contract?

Answer 1

Do you have an example of the endpoint your trying to get to?

My guess would be your trying to access an endpoint that doesn't return anything, the web server still tries to serve you a atom feed but fails. I have had this numerous times while working with SData until I find the correct endpoints for the Resource Kinds I'm wanting to work with.

Couple of tips

SData URL takes the following form;

<protocol>://<hostname>:<port>/sdata/<application>/<contract>/<resourcekind>?<queryparameters>

Couple of useful system urls which may help you discover registered endpoints easier;

• <protocol>://<hostname>:<port>/sdata/$system (List all system endpoints)
• <protocol>://<hostname>:<port>/sdata/$system/adapters (List installed adapters)
• <protocol>://<hostname>:<port>/sdata/$system/registry/endpoints (List of registered endpoints)
