Hi All,
I met a problem using readLines function to return the data from
Google
maps.
readLines(url("
http://ditu.google.cn/maps/geo?q=+qianshuichong,+guichi+anhui,+CN&output=csv&key=ABQIAAAAq8Fnd_oUka-7RdS6BrD7GBTqeABoQuNTXS36G_rkiwQnKRW6GBTkns8JpKz6y6dScgB8827dlddUlg
"),
n=1, warn=FALSE)
[1] "200,4,30.6528380,117.4872250"
The above code is ok because the address is English, but it cannot
work
when i change the address into zh-hans (Chinese simplified). See
below.
readLines(url("http://ditu.google.cn/maps/geo?q=+Ç°Ë®³å<http://ditu.google.cn/maps/geo?q=+%E5%89%8D%E6%B0%B4%E5

&language=zh-CN®ion=zh_Hans"),
n=1, warn=FALSE)
When I plug that URL into my browser (Firefox) I get this text on a
white background:
602,0,0,0
When I execute that code in R I get:
[1] "{"
And when I remove the lines restriction I get:
[1] "{"
[2] " \"name\": \" Ç°Ë®³å\\u003chttp://ditu.google.cn/maps/geo?
q= 前水冲\\u003e\","
[3] " \"Status\": {"
[4] " \"code\": 602,"
[5] " \"request\": \"geocode\""
[6] " }"
[7] "}"
I don't read Chinese , however it does appear that there was some sort
of extra processing step that Firefox carried out to arrive at the
displayed text.
[1] "400,0,0,0"
The returned value is wrong. I also tried several other options, but
still have the same problem. The interesting thing is if i paste the
URL
into the IE explorer directly, it do return the correct values.
Anybody can give me some suggestions or hints to solve this?
Thanks a lot.
P.S. See below for the other possibilities i tried.
