我无法让服务器识别JSON POST请求,因为我稍微更改了代码。以前,对于for循环的每次迭代都会发出POST请求,但现在我已将其更改为包含多级JSON数组。
var json=[];
for (var i=0; i < tourList.length; i++){
var data = tourList[i];
json.push({latitude: data.position.ab, longitude: data.position.cb, filename: data.title, stopNum: i});
}
var results= JSON.stringify(json);
console.log(json);
console.log(results);
//this code was previously inside the for loop above, moved it outside
$.ajax({
type: "POST",
url: "../includes/phpscripts.php?action=postTour",
data: results,
datatype: "json",
beforeSend: function(x){
if (x && x.overrideMimeType){
x.overrideMimeType("application/json;charset=UTF-8");
}
},
success: function(data){
if (data == "success")
console.log("Tour update successful");
else
console.log("Tour update failed");
}
});
此时,tourList的长度为6,results
基于Google Maps标记点击,并在Firebug中生成:
[
{"latitude":43.682211,"longitude":-70.45070499999997,"filename":"../panos/photos/1-prefix_blended_fused.jpg","stopNum":0},
{"latitude":43.6822,"longitude":-70.45076899999998,"filename":"../panos/photos/2-prefix_blended_fused.jpg","stopNum":1},
{"latitude":43.682219,"longitude":-70.450828,"filename":"../panos/photos/3-prefix_blended_fused.jpg","stopNum":2},
{"latitude":43.68218,"longitude":-70.45088699999997,"filename":"../panos/photos/4-prefix_blended_fused.jpg","stopNum":3}
]
但是,没有任何内容显示为$_POST
变量,因为$_POST
在调试器中显示为type: array[0]
。所以我没有数据集来运行json_decode
。从我所看到的,JSON是有效的。有什么问题?
答案 0 :(得分:4)
您没有发送键/值,只有值
在ajax改为:
data: {results:results},
在php中
$results=$_POST['results']
现在您可以使用json_deocde($results)

将字符串作为post var。
发送$.ajax({
type: "POST",
url: "../includes/phpscripts.php?action=postTour",
data: {"json": results},
dataType: "json",
beforeSend: function(x){
if (x && x.overrideMimeType){
x.overrideMimeType("application/json;charset=UTF-8");
}
},
success: function(data){
if (data == "success")
console.log("Tour update successful");
else
console.log("Tour update failed");
}
});
使用$_POST["json"]
我不确定你从PHP返回什么,但是,如果它是json,它永远不会等于"success"
编辑:还有一个问题。您的datatype
参数应为dataType
,此参数仅定义从PHP返回的dataType,而不是您发送的内容。
