将Mimeheader添加到apache轴会引发Bad Request

Question

我正在使用apache轴在Java项目中发送SOAP请求。因此，我想通过重写createCall（）方法来添加HTTP标头以进行授权：

private java.lang.String headers;
// then there are codes to fulfill headers which will be a stringified JSON  
    @Override
        public Call createCall() {
            _call = new org.apache.axis.client.Call(this) {

                @Override
                public void setRequestMessage(Message msg) {
                    super.setRequestMessage(msg);

                    MimeHeaders mimeHeaders = msg.getMimeHeaders();

                    if( headers != null )
                    {
                        JSONObject jsonHeaders = null;
                        try {
                            jsonHeaders = new JSONObject(headers.trim());

                            Iterator<String> keys = jsonHeaders.keys();
                            while (keys.hasNext()) {
                                String key = keys.next();
                                if (jsonHeaders.get(key) instanceof String) {
                                    String value = jsonHeaders.get(key).toString();
                                    mimeHeaders.addHeader(key, value);
                                }
                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }

                    }

                }

            };

            return _call;
        }

但是会导致错误异常：

(400)Bad Request
AxisFault
 faultCode: {http://xml.apache.org/axis/}HTTP
 faultSubcode: 
 faultString: (400)Bad Request
 faultActor: 
 faultNode: 
 faultDetail: 
    {}:return code:  400

    {http://xml.apache.org/axis/}HttpErrorCode:400

我可以正确设置标题吗？

Answer 1

发现这是标题格式错误。标头的键必须带有大写的首字母，所以我添加：

key = key.substring(0, 1).toUpperCase() + key.substring(1);
mimeHeaders.addHeader(key, value);
