Due to the version problem, there may be an error in uncaught soapfault exception: [Client] looks like we got no XML document. One of the reasons is that when sending and receiving, a warning is sent together with the data, resulting in a format error

When I used PHP to write soapserver, I couldn’t get the return value correctly. I found several solutions on the Internet, but they didn’t work until someone reminded me that there was something wrong with the data sent, so I could select the data manually

Rewrite

classSoapClientNewextendsSoapClient
{
publicfunction__doRequest($request,$location,$action,$version,$one_way=0)
{
$request=parent::__doRequest($request,$location,$action,$version,$one_way);

$start=strpos($request,'<soap');//Do the processing according to the actual situation.... , if it starts with <?xml, change it to <?xml
$end=strrpos($request,'>');
returnsubstr($request,$start,$end-$start+1);
}
}

Call

$client=newSoapClientNew($url);

can solve the problem

add a few lines to the code,

classSoapClientNewextendsSoapClient
{
publicfunction__doRequest($request,$location,$action,$version,$one_way=0)
{
$request=parent::__doRequest($request,$location,$action,$version,$one_way);

$myfile=fopen("newfile.txt","w")ordie("Unabletoopenfile!");
$txt=$request;
fwrite($myfile,$txt);
fclose($myfile);

$start=strpos($request,'<?xml');//Do the processing according to the actual situation.... , if it starts with <?xml, change it to <?xml
$end=strrpos($request,'>');
returnsubstr($request,$start,$end-$start+1);
}
}

it can be found that the data to be sent generated by the function becomes

the front warning is the cause of soap error. In addition to appeal settlement, follow the prompts to add always in php.ini file_ populate_ raw_ post_ If the semicolon in front of data = - 1 is removed and warning disappears, the problem of error reporting can also be solved
