使用jQuery将POST主体设置为JSON对象
我正在尝试在Sinatra应用程序中编写基于JSON的Web API。我想发布一个JSON对象作为发布正文（设置了正确的内容类型），但是我很挣扎。
在可可中，我会做类似的事情
[mutableHTTPRequest setHTTPBody:dataRepresentationOfJSONObject];然后将内容类型设置为JSON，然后将HTTP正文作为JSON对象发布。我正在尝试使用jQuery。到目前为止，我能做的最好的就是将JSON对象转换为普通key=value&…样式的文章正文，而这
并不是 我所追求的。
我的Javascript：
var data = { "user" : "me!" };$.ajax({ type: "POST", url: "/api/user/create", contentType: ''application/json'', data: data, success: function(r) {});关于如何执行此操作的任何指示？我的目标是让我的Sinatra做到如下
post "/api/user/create" do js = JSON.parse(request.body.read) # do something with the js object… this works when POSTing from Cocoaend答案1
小编典典将processData参数添加到您的Ajax请求中并将其设置为false。此外，您需要对对象进行字符串化以将其转换为JSON。
var data = { "user" : "me!" };$.ajax({ type: "POST", url: "/api/user/create", processData: false, contentType: ''application/json'', data: JSON.stringify(data), success: function(r) { }});JSON.stringify除非您实现它，否则在旧版本的IE中将无法使用。http://json.org
ios – RestKit 0.20 JSON对象被序列化为POST主体中的GET样式请求
我刚刚开始使用RestKit 0.20.0,我在创建格式良好的
JSON请求时遇到了麻烦.
我得到这个(从休息工具包日志)：
request.body=title=A%20glorIoUs%20walk%20in%20the%20woods&startDateTime=2013-01-13%2016%3A09%3A33%20%2B0000&endDateTime=2013-01-13%2016%3A09%3A43%20%2B0000&points[][longitude]=-122.0307725&points[][latitude]=37.3310798&points[][longitude]=-122.0307334&points[][latitude]=37.33154242&points[][longitude]=-122.03075743&points[][latitude]=37.33138305&points[][longitude]=-122.03075659&points[][latitude]=37.33131185&points[][longitude]=-122.03057969&points[][latitude]=37.33156519&points[][longitude]=-122.03075535&points[][latitude]=37.33144466&points[][longitude]=-122.03076342&points[][latitude]=37.33123666&points[][longitude]=-122.03074488&points[][latitude]=37.33149482&points[][longitude]=-122.03068145&points[][latitude]=37.33155419&points[][longitude]=-122.03062909&points[][latitude]=37.33156564&points[][longitude]=-122.03076853&points[][latitude]=37.33115792
当我想要这个(带有大括号的普通json对象和points属性的数组)时：
{
title: "Something",startDateTime: "dateinfo",endDateTime: "moredateinfo",points: [
{
latitude: "37.33131313",longitude: "122.4325454"
},{
latitude: "37.33131313",longitude: "122.4325454"
}
]
}
我有两个主要对象：DLWalk包含一个DLPoint对象的NSSet(它们是CoreData对象,但目前我忽略了它,只关注创建HTTP请求)
这是我用来创建请求的代码：
// Point mapping
RKObjectMapping *mappingPoint = [RKObjectMapping requestMapping];
[mappingPoint addAttributeMappingsFromArray:@[@"latitude",@"longitude"]];
RKRequestDescriptor *reqDescPoint = [RKRequestDescriptor requestDescriptorWithMapping:mappingPoint objectClass:[DLPoint class] rootKeyPath:nil];
// Walk mapping
RKObjectMapping *mappingWalk = [RKObjectMapping requestMapping];
[mappingWalk addAttributeMappingsFromArray:@[@"endDateTime",@"startDateTime",@"title"]];
RKRequestDescriptor *reqDescWalk = [RKRequestDescriptor requestDescriptorWithMapping:mappingWalk objectClass:[DLWalk class] rootKeyPath:nil];
// Define the relationship mapping
[mappingWalk addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"points" toKeyPath:@"points" withMapping:mappingPoint]];
RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://192.168.1.10:8080"]];
[manager addRequestDescriptor:reqDescWalk];
[manager addRequestDescriptor:reqDescPoint];
[manager addResponseDescriptor:responseDescriptor];
// POST to create
[manager postObject:walk path:@"/walk/save" parameters:nil success:nil failure:nil];
所以问题是：为什么我的POST主体中没有看到正常的JSON对象？
解决方法
你得到的是request.body是URL编码的,这是RESTKit的默认行为,通常工作正常.
如果您希望它是JSON编码的,只需在发布查询之前插入此行
manager.requestSerializationMIMEType=RKMIMETypeJSON;
有关这方面的更多信息,请查看RKObjectManager类的api文档：
requestSerializationMIMEType
javascript – 使用jQuery将json对象下载为json文件
我正在寻找方法下载一个stringfied json对象作为文件..
我确实有一个解决方案,如这个小提琴示例中所示：
FIDDLE
我的工作版看起来像这样
HTML
From data attribute of span:
<span id="a-data"></span>
<span id="obj-data" data-obj2='{"obj-1": "text-1","obj-2": "text-2","obj-3": "text-3"}'></span>
JavaScript的
var obj = $("#obj-data").data("obj2");
var data = "text/json;charset=utf-8," + encodeURIComponent(JSON.stringify(obj));
$('<a href="data:' + data + '" download="data.json">Download Me</a>').appendTo("#a-data");
如果我可以使用这个HTML,我更喜欢.你能建议一种接近的方法吗？
From data attribute of self:
<div id="data" data-obj='{"obj-1": "text-1","obj-2": "text-2","obj-3": "text-3"}'>
Download Me
</div>
解决方法:
尝试将“application / json”替换为“text / json”,在DOM元素a上调用.click(),删除at click handler
$("#data").click(function() {
$("<a />", {
"download": "data.json",
"href" : "data:application/json," + encodeURIComponent(JSON.stringify($(this).data().obj))
}).appendTo("body")
.click(function() {
$(this).remove()
})[0].click()
})<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<div id="data" data-obj='{"obj-1": "some text","obj-2": "text-2","obj-3": "text-3"}'>
Download Me

我的控制器：
@RequestMapping(value = MappingConstants.RULE_ASSIGNMENT,method = RequestMethod.POST)
public String saveRuleAssignment(@RequestBody RuleAssignmentCO ruleAssignment) {
return MappingConstants.REDIRECT + MappingConstants.RULE_ASSIGNMENT;
}
我的jQuery javascript：
ruleAssignment = {
titleId: titleId,typeId: typeId,seriesId: seriesId
}
jQuery.ajax({
url: 'ruleAssignment',type: 'POST',dataType: 'json',data: ruleAssignment,contentType: 'application/json',success: function(result) {
console.log('here');
}
});
解决方法
jQuery不会自动将Javascript对象编码成JSON,您需要使用JSON.stringify()手动进行操作：
jQuery.ajax({
url: 'ruleAssignment',data: JSON.stringify(ruleAssignment),success: function(result) {
console.log('here');
}
});
请注意,某些浏览器不支持JSON.stringify()作为内置方法,在这种情况下,您需要json2.js才能进行可移植性.
jquery – 将字符串转换为JSON对象
如何将字符串转换为对象？我面临这个问题，因为我试图读取JSON字符串中的元素使用“每个”。
我的字符串如下。
jsonObj = "{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}"
我使用eval和我已经使用
var obj = $.parseJSON(jsonObj);
我也用过
var obj= eval("(" + jsonObj + ")");
但它总是null
解决方法
将字符串括在单引号中应该可以工作。尝试这个。
var jsonObj = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var obj = $.parseJSON(jsonObj);
Demo
