微信公众平台，作为自媒体的旗舰级产品，越来越多的人已经投入它的怀抱。正如它的广告词所说：再小的个体，也有品牌
好吧，闲话不多说，今天要说的是它的IP白名单机制。
我们现在安装的大部分都是电信的家庭宽带，它的公网IP是随机的，当然也可以加钱变成固定IP，也可以通过其他软件映射，都可以变成固定IP
我说的这个方案，也算其中一种吧，就是通过WebAPI方式，把某一台机器的公网IP固定，然后访问公众号的程序部署在这上面，最后这些程序再通过WebAPI方式被其他客户端调用
好了，还是上代码吧
//3,需先将封面上传至目标公众号 //3.1,下载原公众号中封面图片.判断是否存在?不存在,则下载 //注:需判断文件夹是否存在?若不存在,则创建 string folderName = CurrentAppInfo.AppPath + @"\MaterialFile\thumb\"; if (!Directory.Exists(folderName)) { Directory.CreateDirectory(folderName); } string fileFullName = folderName + sourceThumbMediaId + ".png"; FileInfo fi = new FileInfo(fileFullName); if (!fi.Exists) { string sourceAccessToken = this.wxpService.GetAccessToken(this.sourceSourceID); Stream imageStream = this.wxpService.GetMaterial(sourceAccessToken, sourceThumbMediaId); Image image = Image.FromStream(imageStream); Bitmap bitmap = new Bitmap(image); bitmap.Save(fileFullName); } //3.2,再上传至目标公众号 //此处是上传封面图片 string targetAccessToken = this.wxpService.GetAccessToken(this.targetSourceID); UploadMaterialApiResultModel modelApiResult1 = this.wxpService.UploadMaterialAny(targetAccessToken, new wxpmaterialBillModel() { IsTemp = "0", FileFullName = fi.FullName, MaterialType = MaterialType.thumb.ToString() }); string targetThumbMediaId = modelApiResult1.media_id; //3,加工数据 wxpapiaccountBillModel modelSourceApiAccount = this.listApiAccount.FirstOrDefault(c => c.SourceID == this.sourceSourceID); wxpapiaccountBillModel modelTargetApiAccount = this.listApiAccount.FirstOrDefault(c => c.SourceID == this.targetSourceID); content = content.Replace(modelSourceApiAccount.SourceCode, modelTargetApiAccount.SourceCode); content = content.Replace(modelSourceApiAccount.SourceName, modelTargetApiAccount.SourceName); //二维码图片可能有多个,分隔符是:分号 //注:目标地址只获取第1个即可 string[] qrcodeUrl1s = modelSourceApiAccount.QRCodeUrlPath.Split(';'); string qrcodeUrl2 = modelTargetApiAccount.QRCodeUrlPath.Split(';')[0]; foreach (string qrcodeUrl1 in qrcodeUrl1s) { content = content.Replace(qrcodeUrl1, qrcodeUrl2); } UploadNewsModel modelUpload = new UploadNewsModel() { title = title, author = author, digest = digest, content = content, content_source_url = targetSourceUrl, show_cover_pic = "0", thumb_media_id = targetThumbMediaId }; //4,上传素材至目标公众号 UploadMaterialApiResultModel modelResult = this.wxpService.UploadMaterialNews(targetAccessToken, new List<UploadNewsModel>() { modelUpload }); //4.1,需标记源公众号中此素材已转发 wxpmaterialBillModel modelEditToSource = new wxpmaterialBillModel() { SourceID = this.sourceSourceID, MaterialCode = this.sourceMaterialCode, IsTranspond = "1", ActionName = "SetIsTranspond", }; this.wxpService.UpdateMaterial(new List<wxpmaterialBillModel>() { modelEditToSource });
如上图所示，这是实现图文素材从公众号A复制至公众号B里的代码，这种情况下，我每天在家里打开电脑时，都要在IP白名单中重新设置下电脑的公网IP，不然，会提示
改成下面的代码就可以轻松解决，我把程序部署到阿里云上，so easy，换个思路，又是一片新的天空。
copymaterialQueryModel copymaterialParamModel = new Base.Models.copymaterialQueryModel()
{
sourceSourceID = this.sourceSourceID,
sourceMaterialCode = this.sourceMaterialCode,
targetSourceID = this.targetSourceID,
title = title,
digest = digest,
author = author,
targetSourceUrl = targetSourceUrl,
wxAccessToken = wxAccessToken
};
UploadMaterialApiResultModel modelResult = WebAPIHelper.WebAPIPostData<UploadMaterialApiResultModel>(ControllerName.WXPublicApi, WXPublicApiActionName.CopyMaterial.ToString(), copymaterialParamModel);
最后，发布一个彩蛋，做自媒体的可以看看
