Play 1.x 功能测试乱码及编码问题 （Encoded Question In Play 1.x FunctionalTest）
大家在估做功能测试的时候，不知有没有发现，如果统一用utf-8作为编码，POST测试请求中如果带有汉字就会乱码。
{"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":"[email protected]"}
这个是一个典型的编码问题，但是我找遍play也没有找到相关的设置，只好用调试看看。
1.我在从yml文件读取数据过程，我发现数据还不是乱码
2.在请求到达第七章提及的ActionInvoker中的时候，已经乱码。
所以我推测，应该是play框架对POST请求进行封装是出了问题在所有功能测试父类FunctionalTest中，重载了许多POST方法，其中根本是这个POST: play.test.FunctionalTest.java
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);
}
在这个方法中，有一个new StringPart()的方法
parts.add(new StringPart(key, parameters.get(key)));
我跟进去之后，发现这厮也是重载方法： com.ning.http.multipart.StringPart.java
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);
}
代码一目了然，
super(name, "text/plain", charset != null ? charset : "US-ASCII", "8bit");
如果没有charset，他就会默认“US-ASCII”! 问题出来的，解决方法就多了，可以在StringPart处将默认的改为“UTF-8”，也可以在POST方法中多传一个“UTF-8”参数。 但是，这两个方法都不太优雅，我这里提供一种方法。首先构造一个测试类的父类： function.BasisTest.java
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;
}
}
覆盖FunctionalTest的POST类，并构建自己的Request,这个地方还可以设定cookie，方便在有登陆拦截的情况下，进行功能测试。这里主要是设定请求的encoding。 然后在FunctionalTest中POST方法中将StringPart构造方法该为三个参数，加上request.encoding。
parts.add(new StringPart(key, parameters.get(key), request.encoding));
这样编码就是活的，可以自行设定。
