HttpClient = INVALID URI - Escaped absolute path not valid
提问by david
I am trying to upload/delete a file to webdav server using HttpClient. However, none is working whenever I have a file name consist of space . I got a error message saying "INVALID URI--- Escaped absolute path not valid".
我正在尝试使用 HttpClient 将文件上传/删除到 webdav 服务器。但是，每当我的文件名由 space 组成时，都没有工作。我收到一条错误消息，指出“无效的 URI --- 转义的绝对路径无效”。
this my URL = "http://localhost:8080/test file.txt"
这是我的 URL = "http://localhost:8080/test file.txt"
private boolean delete(String fileName) {
HttpClient client = new HttpClient();
HttpHost host = new HttpHost(WEBDAV_URL, PORT_NUMBER);
client.getHostConfiguration().setHost(host);
DeleteMethod del = new DeleteMethod(WEBDAV_URL_COMPLETE + fileName);
try {
client.executeMethod(del);
return true;
} catch (HttpException e) {
e.printStackTrace();
return false;
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
is there any method or URL parse should I use to fix the problem

You should simply rename your file as:
您应该简单地将文件重命名为：
test_file.txt or textFile.txt
It is common standard to never use spaces when coding variables or creating files for such.
在编码变量或为其创建文件时从不使用空格是常见的标准。
Use test_file (snake case) or textFile (camelCase).
使用 test_file (snake case) 或 textFile (camelCase)。
