私は1つのグリッドや画像を含むAsp.Netページを持っています。画像はGoogleのチャートチャートであり、そのURLは、周りの1600文字です。一緒にIアウトグリッドと画像を含む.htmファイル。グリッドのために私はそのHTMLコードを取得するにはRenderControlを使用し、画像のために、私はただのimg HTMLタグを追加し、そのSRCにURLをASSING。私は、電子メールの添付ファイルとして、この.htmファイルを送っています。
私の問題は、あなたが添付ファイルを開こうとすると、あなたは（それが何も表示されません、あなたはページのソースコードを見ると、imgタグがいずれかを示していない画像を除いて、[OK]すべてを見ることですSRC一切 - それだけのショーの（スペース）せず、あなたがそれをディスクに保存した後、ファイルを開く場合、そのすべてが正常に動作し、あなたが実際のimg srcを見るのはなぜ???
ここに私のHTMLヘッダーです：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html><head><META http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body>
そして、ここではイメージです。

問題は、URLの大きさであれば、私の選択肢は何ですか、pdfファイルを構築し、それを取り付ける短いですか？これは、htmlファイルは、私が必要とするすべてであるようだと、私はそれをシンプルに保つしたいと思います。
解決
あなたは間違いなく、長いURLの問題を見てすることができます。私は（Railsのではなく、ASP.NETでいえ）GoogleのチャートAPIを使用していたとき、それは私に起こりました。私は問題を起こすために始めた、正確なURLのサイズを見つけることができなかったんが、一部の人は1024年から始まるトラブルを報告します。
Googleは、あなたがそれを縮小する入力データに使用することができます異なる符号化タイプのカップルを提供していますが、その心配している場合、データをスケーリングする能力を無効にしますテキストエンコーディング（あなたが何をしているか）以外のものを使用しました。
あなたがデータをスケーリングすることができない場合は、データが長いストレッチのためか、あなたが異なるスケールを持つ2匹のグラフをオーバーレイしたい場合は、最大でとどまる場合は、、あなたはいくつかの醜いのグラフを得ることができます。
を参照してください。データ形式は、GoogleのチャートAPIのドキュメントからを
他のヒント
GETが長すぎる場合は、代わりにあなたは十分以上である16Kの制限があるでしょうPOSTを使用することができます。私はあなたのチャートを生成するために、以下のコードを使用しましたし、それが働きました。そうです、私はあなたがポストを使用して電子メールに添付しているのことができると思います。おそらく、GETを使用しての問題は、画像ファイルを開かないように設定電子メールクライアントの問題です、あなたは他のクライアントでそれをテストしている？
