我想安装Lxml,然后我可以安装Scrapy.

当我今天更新我的Mac时它不会让我重新安装lxml,我收到以下错误:

In file included from src/lxml/lxml.etree.c:314:
/private/tmp/pip_build_root/lxml/src/lxml/includes/etree_defs.h:9:10: fatal error: 'libxml/xmlversion.h' file not found
#include "libxml/xmlversion.h"
         ^
1 error generated.
error: command 'cc' failed with exit status 1

我已经尝试使用brew来安装libxml2和libxslt,两者都安装得很好但我仍然无法安装lxml.

上次我安装时我需要在Xcode上启用开发人员工具,但由于它更新到Xcode 5,它不再给我这个选项了.

有谁知道我需要做什么？

我已经使用oAuth2从谷歌api获得了用户访问令牌.现在我想使用此令牌来获取用户事件/日历.我试过以下代码,但它无法正常工作.

请有人在这帮我这个.谢谢

    var urlBuilder = new System.Text.StringBuilder();

    urlBuilder.Append("https://");
    urlBuilder.Append("www.googleapis.com");
    urlBuilder.Append("/calendar/v3/users/me/calendarList");
    urlBuilder.Append("?minAccessRole=reader");

    var httpWebRequest = HttpWebRequest.Create(urlBuilder.ToString()) as HttpWebRequest;

    httpWebRequest.CookieContainer = new CookieContainer();
    httpWebRequest.Headers["Authorization"] string.Format("Bearer {0}", data.access_token);
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    Stream eventResponseStream = response.GetResponseStream();
    StreamReader eventResponseStreamReader = new StreamReader(responseStream);
    string eventsStr = eventResponseStreamReader.ReadToEnd();

我在母版页上有一个隐藏字段.我通过JavaScript在子页面上设置它的值.当我单击此子页面上的链接时,它会重定向到另一个页面.现在我想在这个新的子页面上获取隐藏的字段值.但是价值很明显(很明显).我怎样才能坚持这个价值.

任何人都可以提前帮助.

我在使用JQUERY AJAX消费WCF服务时遇到问题。我知道这是跨域问题，并且已经阅读了很多解决方案。但没有一个对我有用。以下是所有相关代码。有人可以帮我吗？

谢谢

        [WebInvoke(Method = "POST",BodyStyle=WebMessageBodyStyle.Bare,
            RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json)]
        [return: MessageParameter(Name = "result")]


        public ServiceSearchResponse GetSearchResults(ServiceSearchParams sParams)
        {
            /// search function
        }

JQUERY：

        $.ajax({
            type: 'POST',
            url: "http://myserviceurl.com/GetSearchResults",
            data: p,
            contentType: "application/json; charset=utf-8",
            dataType: 'json',
            crossDomain: true,
            success: function (data) {

                alert(data);
            },
            failure: function (response) {
                alert('failed');
            },
            error: function (response) {
                alert(JSON.stringify(response));
            }
        });

我们目前在使用docusign开发集成Web解决方案时遇到一些技术难题.您能否就以下事项提出建议:

1)我们如何在基于文档的rest api调用上为收件人分配签名顺序？我们可以有一个json示例吗？

2)我们目前无法为已添加到已创建信封的用户检索签名网址.此代码以前用于基于模板的信封创建,但不适用于基于使用PDF的代码.

对docusign API的调用和响应(删除了密码)如下所示.已经尝试了两种失败的认证方法.通过信封中找到的任一电子邮件进行检索也会失败.
