RussianQuestion
J'ai un Asp.Net page contenant une grille et une image.L'image est un google cartes graphique et son url est autour de 1600 caractères.- Je avec une .htm fichier contenant la grille et de l'image.Pour la grille, je utiliser RenderControl pour obtenir son code html, et pour l'image, j'ai juste ajouter une balise html img et assing l'url de sa src.J'ai ensuite envoyer cette .htm fichier en tant que pièce jointe à un email.
Mon problème est que lorsque vous essayez d'ouvrir le fichier joint, vous voyez tout est ok sauf l'image (ce n'est pas rien et quand vous regardez le code source de la page, la balise img ne pas montrer toute la src que ce soit, cela montre juste < img > (sans les espaces).Si vous ouvrez le fichier après vous enregistrer sur le disque dur, alors tout fonctionne bien et vous verrez la réelle img src.Pourquoi???
Voici mon code html:
<!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>
Et voici l'image:

Si le problème est la taille de l'URL, ce sont mes choix, à la construction d'un fichier pdf et de le fixer?Il semble qu'un fichier html est tout ce dont j'ai besoin et je tiens à garder les choses simples.
La solution
Vous pourriez certainement être voir un problème à long URL. Ce qui est arrivé à moi quand j'utilisais API graphiques Google (bien que dans Rails plutôt que ASP.NET). Je ne pouvais trouver la taille d'URL exacte qui a commencé à causer des problèmes, mais certaines personnes ont déclaré des problèmes à partir de 1024.
Google propose deux différents types de codage que vous pouvez utiliser sur les données d'entrée pour le rétrécir, mais en utilisant autre chose que l'encodage de texte (ce que vous faites) désactivera votre capacité à l'échelle les données, si vous tenez à ce sujet.
Si vous ne pouvez pas l'échelle les données, vous pouvez obtenir des graphiques laides si les données restent au maximum pendant de longues périodes ou si vous voulez superposer deux graphiques à différentes échelles.

Autres conseils
Si le GET est trop long, vous pouvez utiliser un POST au lieu de cela, vous aurez un 16k limite de ce qui est plus que suffisant.J'ai utilisé le code ci-dessous pour générer votre tableau et il a travaillé.Donc, oui, je suppose que vous pourriez utiliser de la poste et de le joindre à l'e-mail.Peut-être le problème avec l'utilisation de GET est un problème avec le client de messagerie configuré pour ne pas ouvrir des fichiers image, avez-vous testé d'autres clients?
