这是发出请求的页面
var customStore = new DevExpress.data.CustomStore({
load: function(loadOptions) {
return $.getJSON('/erg/api/api/Caveats');
},
byKey: function(key) {
return $.getJSON('http://webcrm/erg/api/api/Caveats' + "/" + encodeURIComponent(key));
},
insert: function(values) {
return $.post('http://webcrm/erg/api/api/Caveats', values);
},
update: function(key, values) {
return $.ajax({
url: 'http://webcrm/erg/api/api/Caveats' + "/" + encodeURIComponent(key),
method: "PUT",
data: values
});
},
remove: function(key) {
return $.ajax({
url: 'http://webcrm/erg/api/api/Caveats' + "/" + encodeURIComponent(key),
method: "DELETE",
});
},
key: "CaveatID"
});
这是控制器

只有put请求失败并返回400错误请求错误。其他人使用普通的200次成功代码
我尝试了一切可能，包括使用fiddler来分析错误。我可以在更明亮的地方打开网址，并可以看到我在ajax中格式化的所有数据。
这是webconfig文件

请检查您的Asp.NET webapi项目中是否有以下配置条目。您必须删除WebDAv和WebDAVModule以允许PUT和DELETE。
<system.webServer>
<handlers>
<remove name="WebDAV" />
</handlers>
<modules runAllManagedModulesForAllRequests="true">
<remove name="WebDAVModule" />
</modules>
</system.webServer>
如果仍然无效，请通过IIS管理器中的Handler Mappings验证是否允许PUT动词。查找ExtensionlessUrlHandler-Integrated-4.0，双击打开它。下一步单击“请求限制”按钮并选中“动词”选项卡，如果缺少则添加PUT或选择“允许所有动词”。
<强>更新
将PUT调用的客户端代码修改为此
update: function(key, values) {
return $.ajax({
url: 'http://webcrm/erg/api/api/Caveats/' + encodeURIComponent(key),
type: 'PUT',
contentType: 'application/json; charset=utf-8',
data: values
});
}
