Javascript Yammer REST Api从不同页面进行不同调用

我有一段简单的代码，使用Yammer JavaScript api查找Yammer上用户可用的组，它看起来有点像这样：

yam.platform.request({
 url: "groups.json?mine=1",
 method: "GET",
 success: function (data) {
     callback(data);
 },
 error: function (error) {
     console.log(error);
 },

Response Headers

})

调用经过仔细包装，因此每个页面请求只发生一次调用，但它似乎完全是在任意基础上成功或失败的。响应如下所示：

yam.platform.request({
 url: "groups.json?mine=1",
 method: "GET",
 success: function (data) {
     callback(data);
 },
 error: function (error) {
     console.log(error);
 },

或者像这样：

yam.platform.request({
 url: "groups.json?mine=1",
 method: "GET",
 success: function (data) {
     callback(data);
 },
 error: function (error) {
     console.log(error);

在前一种情况下，我在开发工具的网络面板中看到一条错误消息，如下所示：

yam.platform.request({
 url: "groups.json?mine=1",
 method: "GET",
 success: function (data) {
     callback(data);

 error: function (error) {
     console.log(error);

无法加载XMLHttpRequest . 不 “Access Control Allow Origin”标头出现在请求的服务器上 资源起源是 因此不允许访问。响应的HTTP状态代码为429

这没有意义，原因有两个——首先，请求在两种情况下都完全相同，其次，我收到了429个太多的请求作为状态代码，但有一个明确的报告，即应该设置Access-Control-Allow_origin头。这在我的请求中从未出现过，但在成功的回复中确实出现过

有人能解释一下发生了什么吗？

首先确保您在Yammer注册的应用程序的Javascript源中找到了web url

如果仍然存在相同的问题，则可能是：

这与Yammer rest API限制有关，更多的是429错误

请参考我在这篇帖子上的答案

由于访问控制源，我也面临类似问题。一些api集仅在www.yammer.com上可用，不在api.yammer.com中，SDK使用的是api.yammer.com，其中groups.json api有问题。我发送的请求没有太多，仍然显示此问题。PS-开发人员文档中没有关于此API的文档。我的问答链接：
