背景
zuul的作用类似于nginx, 有时候我们希望在使用zuul代理的同时, 添加一些固定参数
1 添加post参数
public Object run() {
RequestContext ctx = RequestContext.getCurrentContext();
HttpServletRequest request = ctx.getRequest();
try {
InputStream in = request.getInputStream();
String body = StreamUtils.copyToString(in, Charset.forName("UTF-8"));
if(StringUtils.isNotEmpty(body))
body += "&";
body += "clientId=3";
final byte[] reqBodyBytes = body.getBytes();
ctx.setRequest(new HttpServletRequestWrapper(request){
@Override
public ServletInputStream getInputStream() throws IOException {
return new ServletInputStreamWrapper(reqBodyBytes);
}
@Override
public int getContentLength() {
return reqBodyBytes.length;
}
@Override
public long getContentLengthLong() {
return reqBodyBytes.length;
}
});
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
2添加get参数
@Override
public Object run() {
RequestContext ctx = RequestContext.getCurrentContext();
HttpServletRequest request = ctx.getRequest();
String method = request.getMethod();
List<String> clientParam = new ArrayList<>();
clientParam.add("3");
Map<String, List<String>> qp = HTTPRequestUtils.getInstance().getQueryParams();
qp.put("clientId", clientParam);
}
