Asked Xiadu Niang and said that when a web service is called remotely, the IIS configuration must be “allow anonymous access”. How to configure it?This computer – > computer   -> Administration   -> Services and Applications   ->   Internet Informatica Services(IIS) -> Double click “authentication” – > under IIS in the pop-up window on the right; Right click anonymous authentication – > Enabled

If IIS has not been opened, open it as follows: control panel – > Procedures and functions – > Turn windows features on or off  -> Internet Informatica Services  -> Web management tools  -> Tick “IIS management console”


I opened the IIS configuration on my computer and found that anonymous authentication had been checked. The configuration problem was eliminated. Then I continued to check and found that I put the marketplaceid into the merchant ID to request when setting parameters. In fact, merchantid is sellerid. If you change it and ask again, it will return normally:
