Google Charts API FAQ提供以下建议:

Is there a limit on the URL length for the Google Chart API? What is the maximum URL length?

The maximum length of a URL is not determined by the Google Chart API, but rather by web browser and web server considerations. The longest URL that Google accepts in a chart GET request is 2048 characters in length, after URL-encoding (e.g., | becomes %7C). For POST, this limit is 16K.

If URL length is a problem, here are a few suggestions for shortening your URL:

• If you are using a text encoding data format, remove leading zeros from numbers, remove trailing zeros after decimal points, and round or truncate the numbers after decimal points.
• If that does not shorten the URL enough, use simple (1 character) or extended (2 character) encoding.
• Sample data less frequently; i.e., reduce granularity.
• Remove accoutrements and decorations, such as colors, labels, and styles, from your chart.

也发现了这一点，但似乎没有答案/解决方案。
