, especially for RESTful interfaces. The big grab kits, such as Chrome's own developer tools, Firebug, and Fiddler, will show JSON data in a tree-like structure, very friendly. But there are also some service-side languages that do not support this approach, such as PHP's inability to get content from the above request through the $_post object. At this point, you need to do it yourself: When the Content-type is Application/json in the request header, the original input stream is obtained from t

1. The difference between abstract classes and interfaces:Abstract classes are classes that cannot be instantiated, and are decorated by the abstract keyword.An abstract method is a method that does not have a method body, that is, an empty method, a method that is specifically implemented by a quilt or extension class.Interfaces are abstract classes that are more abstract, because non-abstract methods are allowed in abstract classes (even without an abstract method), and all methods in an inter

If there is an array can also say *a=25, we test this thing, the result is *a for 1120, visible *a readable can be written, in short, can be used as pointers.The array variable is a const pointer, as mentioned in the previous array, if the definition of two arrays, int a[],int b[], so that b=a is not possible, between the array can not be assigned value.
