Detailed explanation of the case of passing json parameters in the $http service Post method
Detailed explanation of the case of passing json parameters in the $http service Post method
This time I will bring you a detailed explanation of the case of passing json parameters by the $http service Post method. What are the precautions for the $http service Post method of passing json parameters? The following is a practical case, let's take a look.
The details are as follows:
1. The default data type submitted by the $http POST method is application/json
var data = {'wid':'0', 'praise' : '25'};
$http.post(url, data).success(function(result) {
//
});The final request sent is:
POST http://www.example.com HTTP/1.1
Content-Type: application/json;charset=utf-8
{'wid':'0','praise':'25'}The default method can directly pass the json object to the server in the form of string, which is more suitable for RESTful interfaces. But the $_POST of the php script cannot get the json data from the request body.
You can use this:
$data = file_get_contents("php://input"); //获得原始输入流Note: php://input is invalid when enctype="multipart/form-data"
After obtaining the original input stream of the request and then processing it accordingly, you can get the json data.
2. Submit the json data using x-www-form-urlencoded method
app.factory("Comment",function($http){
return {
get : function(commentFileUrl) {
return $http({
method: "GET",
url: commentFileUrl,
params: {R:Math.random()},
headers: {'Cache-Control':'no-cache'}
});
},
//保存一个评论
save : function(toUrl,saveFileUrl,Data) {
$http({
method: "POST",
url: toUrl,
data: {saveUrl:saveFileUrl,commit:Data},
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
transformRequest: function(obj) {
var str = [];
for (var p in obj) {
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
}
return str.join("&");
}
}).success(function(data){
console.log("数据已保存！");
}).error(function(data) {
alert("数据保存失败，错误信息:" + JSON.stringify({data:data}));
});
}
}
});
var updateClickRate={'wid':'0','click_rate':'87'};
Comment.save("php/updateWork.php","../userdata/work_content.json",JSON.stringify(updateClickRate));Finally sent request It is:
