微信公眾平臺，作為自媒體的旗艦級產品，越來越多的人已經投入它的懷抱。正如它的廣告詞所說：再小的個體，也有品牌

好吧，閑話不多說，今天要說的是它的IP白名單機制。

我們現在安裝的大部分都是電信的家庭寬帶，它的公網IP是隨機的，當然也可以加錢變成固定IP，也可以通過其他軟件映射，都可以變成固定IP

我說的這個方案，也算其中一種吧，就是通過WebAPI方式，把某一臺機器的公網IP固定，然後訪問公眾號的程序部署在這上面，最後這些程序再通過WebAPI方式被其他客戶端調用

好了，還是上代碼吧

//3,需先將封面上傳至目標公眾號              
//3.1,下載原公眾號中封面圖片.判斷是否存在?不存在,則下載
 
//註:需判斷文件夾是否存在?若不存在,則創建
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,再上傳至目標公眾號
//此處是上傳封面圖片
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,加工數據
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);

//二維碼圖片可能有多個,分隔符是:分號
//註:目標地址只獲取第1個即可
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,上傳素材至目標公眾號                
UploadMaterialApiResultModel modelResult = this.wxpService.UploadMaterialNews(targetAccessToken, new List<UploadNewsModel>() { modelUpload });

//4.1,需標記源公眾號中此素材已轉發
wxpmaterialBillModel modelEditToSource = new wxpmaterialBillModel()
{
    SourceID = this.sourceSourceID,
    MaterialCode = this.sourceMaterialCode,
    IsTranspond = "1",
    ActionName = "SetIsTranspond",
};
this.wxpService.UpdateMaterial(new List<wxpmaterialBillModel>() { modelEditToSource });

如上圖所示，這是實現圖文素材從公眾號A復制至公眾號B裏的代碼，這種情況下，我每天在家裏打開電腦時，都要在IP白名單中重新設置下電腦的公網IP，不然，會提示

改成下面的代碼就可以輕松解決，我把程序部署到阿裏雲上，so easy，換個思路，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);

最後，發布一個彩蛋，做自媒體的可以看看
