android - Uri Builder in android - '/' replaced by '%2F' and ":" is replaced by "%3A"

Question

I want to build the following URI -

https://10.112.88.182:8443/Vehicle/services/socialService/login

...

Builder builder = new Builder();
builder.scheme(Constants.URL_SCHEME);
builder.authority(host);
builder.appendPath(service + "/" +method);
return builder.build().toString();

where

• URL_SCHEME - https
• host - 10.112.88.182:8443/Vehicle/services/
• service - socialService
• method - login

When this code runs I get the following URI -

https://10.112.88.182%3A8443%2FVehicle%2Fservices%2F/socialService%2Flogin

/ is replaced by %2F and : is replaced by %3A

Answer 1

就是这样Uri.Builder工作的。它将具有特殊含义的非安全 URL 字符编码为%xx十六进制值。

要防止对已经正确编码的 URI 部分进行编码，请使用encoded构建器函数的版本：

builder.encodedAuthority(host);
builder.appendEncodedPath(service + "/" +method);

但是由于您的所有 URL 部分都已准备好并且不需要任何进一步的编码，因此使用常规StringBuilder连接部分更容易。

就像 laalto 说的那样，这就是 Uri.Builder 的工作方式，但是如果您想以常规 url 形式获取 uri，就像您的情况一样：https://10.112.88.182:8443/Vehicle/services/socialService/login 您可以这样做：

URL url = new URL(URLDecoder.decode(builder.build().toString(), "UTF-8"));

Answer 3

解决方案非常简单，只需使用appendEncodedPath()，它不会对您的字符串进行编码，它只是按原样附加它。
