(JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x175c65b00 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}

There is no problem with Android. The packet capture shows my local database closing error

No problem uploading to server nginx. My local one is apache

The same interface has no problem accessing Android, but there is a problem with iOS. It should be a problem with parsing JSON on iOS

What is the content-type returned by the interface

You have specified the receiving type as json text, so saving the information will definitely be considered wrong data

Are you using AF to make requests? Try adding the following statement,

<code>self.manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
</code>

It is estimated that the data obtained is incorrect

iOS has strict requirements on data format and return information, please check these two data carefully
