Using HttpClient to upload files under Ssh+ckeditor

Order

The dog, the teacher needs me to implement upload images to the remote file server, said to be load-balanced, resource synchronization, data Security ... Balabala, the reason can say a large basket of ...

As aged respected four good youth, after all, the teacher took me so long, he said what is what ... So do ...

1. Process

All kinds of ask Niang, look at the blog, visit the forum ... HttpClient, HttpURLConnection, FTP, SFTP ... Okay, all right? Various network transport protocols have been tried once and found themselves back to the original point ...

The reason of oneself mentally retarded, lazy ... Just want to copy the code on the Internet, direct use, but there is no good analysis ...

2, confusedbusy for one weeks, the teacher has been urging, but there has been no progress, always want to have an old driver to take me to fly much better, but the more so think, the more I have no confidence, the bitter lesson ... 3. HopeWell, you can't count on an old driver, or on your own. Use Google, on GitHub, read the documentation carefully ... Chat with her sister, Sister encouraged me, and again have confidence in themselves ...slowly, I have a clue, as the villain in the United States 3, said, "As long as there is experience and patience, anything can be done ..."The last reason to choose the HTTP protocol is that the HTTP protocol is probably the most widely used and most important protocol on the Internet now, and more and more Java applications need to access network resources directly through the HTTP protocol. while the basic functionality of accessing the HTTP protocol has been provided in the JDK's java.net package, the JDK library itself provides a lack of functionality and flexibility for most applications. HttpClient is used to provide efficient, up-to-date, feature-rich client programming toolkits that support the HTTP protocol, and it supports the latest versions and recommendations of the HTTP protocol. 4.

PS: A lot of online no server code, too pit, server attention needs two jar files, Commons-fileupload-1.3.1.jar and Commons-io-2.5.jarlast required jar, package download: Link: http://download.csdn.net/detail/sage_wang/9515110
