1. a website is deployed on the local server tomcat. the mobile terminal and the server are connected to the same LAN through WiFi, but the WiFi is not connected to the network cable, and the Internet cannot be accessed.

1. a website is deployed on the local server tomcat.
1, in the local server Tomcat deployed a Web site, mobile phone and server via WiFi connection to the same LAN, but the WiFi is not connected to the network cable, is unable to access the extranet. So how do I access the site through a local IP (such as: http://192.168.1.36/bus/index1.php)?
2, LAN is not connected to the external network, the purpose is to provide users with
Why the local internal class object accesses the local variable must be added with the final keyword.
in the final analysis, the life cycle is different.
local internal classes require GC calls to reclaim, and local variables are discarded on the stack frame stack.
so it is possible that there are
When the function returns a string, we can define a return of string and string.1 Write a function that returns a string referencestd::string TestStringReference(){ std::string"holy shit"; return loal_str;}This function is, of course, wrong and the compiler will prompt us:Returns the address of a local variable or temporary variable: loal_strThat is, you cannot return a reference to a local variable.
In iOS development, it is often used to localize images. IOS image local storage, local fetch, local delete, can be implemented by the following class methods.Save a picture to a local+ (void) saveimagetolocal: (uiimage*) image Keys: (nsstring*) key { First, you need to get the sandbox pathnsstring *picpath=[nsstring
IOS: Local Image Storage, local retrieval, and local deletion. ios RetrievalIOS image local storage, local retrieval, and local Deletion
Image localization is often used in iOS development. IOS images are stored locally, obtained

In practice, the string series in c ++ -- function returns the local variable string (referencing the local string, the. c_str () function of the local string)
When the function returns a string, we can define the return string and string .
1. Write a function that returns a string reference.
