",Onsuccess: function (Transport ){VaR JSON = transport. responsetext. evaljson ();// Todo: Document. Write (JSON. XXX );}}); Server output JSON format data Next we will discuss how to output data in JSON format on the server side. Taking Java as an example, we will demonstrate how to encode a Java object as a JSON text. When you encode a String object in JSON format, you only need to process special characters. In addition, you must use (") Instead (') Indicates a string:

server controls, while convenient to use, also sacrifice performance, and sometimes seem accuse. Hope that advanced friends more advice. Copy Code code as follows: Engineering performance--with a for loop instead of the DataList multiple-column display, get 2 rows of four columns of the table, requires a memory table of 8 rows of data private void Gcyjshow () { StringBuilder sb = new StringBuilder (); PRODUCTBLL PB = new Productbll ();

Android uploads files in two ways. The first is HTTP-based httpurlconnection, and the second is TCP-based socket. The difference between the two methods is that there is a cache mechanism in the httpurlconnection when uploading. If a large file is uploaded, memory overflow occurs. If you use TCP socket to upload data, this problem will be solved. HTTP: httpurlconnection 1. Open an httpurlconnection through the URL encapsulation path 2.

The differences between the two are as follows: The data uploaded by GET is usually very small and has low security performance. The data uploaded by POST is suitable for scenarios with large data volumes, complex data types, and high data security performance requirements. GET and POST are generally used as follows: 1. Steps for passing data to the server using the GET Method 1. Use the Map set to obtain and process dataIf (params! = Null ! Params. isEmpty ()){For (Map. Entry

In this example, the impact may be very small (that is, a small amount of code is given), but doing so in a large application with a lot of operations will degrade the performance. The StringBuffer class must solve this problem.Use StringBuffer to process stringsThe StringBuffer class is designed to use and create and operate dynamic string information.
