Play 1.x 功能測試亂碼及編碼問題 (Encoded Question In Play 1.x FunctionalTest)

你們在估作功能測試的時候,不知有沒有發現,若是統一用utf-8做爲編碼,POST測試請求中若是帶有漢字就會亂碼。java

{"box":[{"entityId":7,"id":7,"idea":"?????","jPAContext":{"insideTransaction":true,"jPAConfig":{"configName":"play","enabled":true,"insideTransaction":true,"jPAContext":{"$ref":".."},"jpql":{}}},"persistent":false,"type":1},{"entityId":8,"id":8,"idea":"???","jPAContext":{"$ref":"$.box[0].jPAContext"},"persistent":false,"type":5},{"idea":"???","jPAContext":{"$ref":"$.box[0].jPAContext"},"persistent":false,"type":3}],"code":"jack","entityId":1003,"id":1003,"ip":"192.168.1.122","jPAContext":{"$ref":"$.box[0].jPAContext"},"nick":"??","passwd":"jack2","persistent":true,"qqmail":"200@qq.com"}


這個是一個典型的編碼問題,可是我找遍play也沒有找到相關的設置,只好用調試看看。 cookie

1.我在從yml文件讀取數據過程,我發現數據還不是亂碼 框架

2.在請求到達第七章說起的ActionInvoker中的時候,已經亂碼。 ide

因此我推測,應該是play框架對POST請求進行封裝是出了問題在全部功能測試父類FunctionalTest中,重載了許多POST方法,其中根本是這個POST: play.test.FunctionalTest.java測試

public static Response POST(Request request, Object url, Map parameters, Map files) {
        List parts = new ArrayList();

        for (String key : parameters.keySet()) {
            parts.add(new StringPart(key, parameters.get(key)));
        }

        for (String key : files.keySet()) {
            Part filePart;
            try {
                filePart = new FilePart(key, files.get(key));
            } catch (FileNotFoundException e) {
                throw new RuntimeException(e);
            }
            parts.add(filePart);
        }

        MultipartRequestEntity requestEntity = new MultipartRequestEntity(parts.toArray(new Part[]{}), null); 
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try {
            requestEntity.writeRequest(baos);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
        InputStream body = new ByteArrayInputStream(baos.toByteArray());
        String contentType = requestEntity.getContentType();
        Http.Header header = new Http.Header();
        header.name = "content-type";
        header.values = Arrays.asList(new String[]{contentType});
        request.headers.put("content-type", header);
        return POST(request, url, MULTIPART_FORM_DATA, body);
    }


在這個方法中,有一個new StringPart()的方法this

parts.add(new StringPart(key, parameters.get(key)));


我跟進去以後,發現這廝也是重載方法: com.ning.http.multipart.StringPart.java編碼

public StringPart(String name, String value, String charset)
    {
        super(name, "text/plain", charset != null ? charset : "US-ASCII", "8bit");
        if(value == null)
            throw new IllegalArgumentException("Value may not be null");
        if(value.indexOf('\0') != -1)
        {
            throw new IllegalArgumentException("NULs may not be present in string parts");
        } else
        {
            this.value = value;
            return;
        }
    }

    public StringPart(String name, String value)
    {
        this(name, value, null);
    }


代碼一目瞭然,url

super(name, "text/plain", charset != null ? charset : "US-ASCII", "8bit");


若是沒有charset,他就會默認「US-ASCII」! 問題出來的,解決方法就多了,能夠在StringPart處將默認的改成「UTF-8」,也能夠在POST方法中多傳一個「UTF-8」參數。 可是,這兩個方法都不太優雅,我這裏提供一種方法。首先構造一個測試類的父類: function.BasisTest.javaidea

public class BasisTest extends FunctionalTest{
    public static Response POST(Object url, Map parameters) {
        return POST(newLocalRequest(), url, parameters, new HashMap());
    }
   
    public static Request newLocalRequest() {
        Request request = Request.createRequest(
            null,
            "GET",
            "/",
            "",
            null,
            null,
            null,
            null,
            false,
            80,
            "localhost",
            false,
            null,
            null
        );
        request.encoding = "utf-8";
        return request;
    }
}


覆蓋FunctionalTest的POST類,並構建本身的Request,這個地方還能夠設定cookie,方便在有登錄攔截的狀況下,進行功能測試。這裏主要是設定請求的encoding。 而後在FunctionalTest中POST方法中將StringPart構造方法該爲三個參數,加上request.encoding。調試

parts.add(new StringPart(key, parameters.get(key), request.encoding));


這樣編碼就是活的,能夠自行設定。
