轉眼又是一個月，回首已經過兩年，唉。

修改了密碼之後登陸app，發現無法登陸直接報錯，趕緊檢視程式碼log：

沒看太明白！

然後觀察HttpLoggingInterceptor列印的請求log發現url引數如下：

║ --> GET https://xxxxxx/index/login?username=xxx&password=ssd123$%^ http/1.1

引數中未編碼的password為ssd123$%^,”^”字元竟然沒有進行url編碼，我記得retrofit預設會自動對不符合規則的引數value進行編碼。

檢視文件可知：

Retrofit中類似@Query，@QueryMap，@QueryName等都會自動進行編碼，

註解定義如下：

@Documented
@Target({ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
public @interface QueryMap {
    boolean encoded() default false;
}

public abstract boolean encoded

Specifies whether the parameter name and value are already URL encoded.

Default:

false

false表示特殊字元已進行url 編碼。

看到這裡解決辦法已經有了，就是encoded = true，然後自己編碼，我設定encoded = true，之後檢視log，不符合規則的請求引數還是會進行編碼。

/**
 * 登入
 */
@GET( BASE_URL + "index/login" )
Observable< LoginResult > requestLogin( @QueryMap(encoded = true) Map< String, String > params );

final Map< String, String > paramsMap = new ParamsProvider.Builder().
        append( "username", account ).
        append( "password",URLEncoded(password) ).
        build();

這裡有個疑問是為什麼自動編碼時沒有對“^”字元進行編碼，很奇怪。
