When using(), it was an IOException error. I couldn't figure it out. I called the same program twice, but one link was always OK, but the other kept reporting this error.
Introduction: I don’t have much contact with the Internet connection. I find some problems when using them and record them.
text:When I use(), I directly reported an IOException error, responseCode = -1. I have been unable to understand it. I called the same program twice, but one link was always OK, but the other kept reporting this error. Later I found the difference between the two links, one of which returned was empty, which led to this error.
Solution:
Method 1. The content returned by the web page cannot be empty;
Method 2. Don’t use this interface.
