模拟提交的问题
参数为：
method GET
model {"searchString":"B0036SGFB6","lang":"ja_JP","marketPlace":"A1VC38T7YXB528"}
源代码为：
method=GET&model=%7B%22searchString%22%3A%22B0036SGFB6%22%2C%22lang%22%3A%22ja_JP%22%2C%22marketPlace%22%3A%22A1VC38T7YXB528%22%7D
请问curl_setopt($ch, CURLOPT_POSTFIELDS, $data)中的$data应该怎么写呢？
回复讨论(解决方案)
$data 是一个关联数组就可以了，关联键就是表单控件的 name
xuzuning大大：
我现在是这样的
$data='method=GET&model='.urlencode('{"searchString":"B0036SGFB6","lang":"ja_JP","marketPlace":"A1VC38T7YXB528"}');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
得到了我想要到结果，但现在有个问题：
$data_ar=array(
"searchString"=>"B0036SGFB6",
"lang"=>"ja_JP",
"marketPlace"=>"A1VC38T7YXB528"
);
请问我怎么把$data_ar提交出去呢？？
我想提交数组出去，而不是一段死的字符串
$data_ar=array(
"searchString"=>"B0036SGFB6",
"lang"=>"ja_JP",
"marketPlace"=>"A1VC38T7YXB528"
)请问我怎么把$data_ar提交出去呢？？;
得到的结果，我用print_r($value)的内容：
{"data":[{"link":"http://www.amazon.co.jp/gp/product/B0036SGFB6/ref=xx_xx_cont_xx/378-0276217-1847765","dimUnits":"センチメ?トル","thumbnail":"https://images-na.ssl-images-amazon.com/images/I/41zK5Evzv2L._SL80_.jpg","subCategory":"14700954","dimensions":{"width":7.3914,"length":20.8026,"height":2.794},"gl":"gl_pc","image":"https://images-na.ssl-images-amazon.com/images/I/41zK5Evzv2L._SL120_.jpg","weightUnits":"キログラム","productGroup":"147","weight":"0.0998","asin":"B0036SGFB6","whiteGlovesRequired":"N","title":"ELECOM USB2.0ケ?ブル A-Bタイプ 2m ブラック U2C-B20BK [Personal Computers]"}],"errorMessage":null}
这不是一个数组吗？为什么$value[0]或$value["data"]没有内容输出？？
你 print_r($value) 得到的是 json 串
需要用 json_decode 解码后才可使用
