我面临一个奇怪的问题。我在本地的nodejs服务器上运行我的angularjs应用程序,它从位于Google App Engine上的应用程序调用POST API。 API配置了所需的所有CORS头,如下所示:
def post(self):
self.response.headers.add_header("Access-Control-Allow-Origin", "*")
self.response.headers.add_header("Access-Control-Allow-Methods", "POST,GET,PUT,DELETE,OPTIONS")
self.response.headers.add_header("Access-Control-Allow-Headers", "X-Requested-With, content-type, accept, myapp-domain")
self.response.headers["Content-Type"] = “application/json; charset=utf-8”
GET请求API工作没有问题。
POST请求API工作但仅当我发送帖子数据作为'字符串'当发布数据作为对象发送时, NOT 是正确的方法。最终我需要能够使用此API上传图片,因此下面的第一个解决方案可能对我不起作用。请帮忙!
方法1:此方法有效:
postMessageAPI = "https://myapp-qa.appspot.com/message";
var postData = "conversationid=1c34b4f2&userid=67e80bf6&content='Hello champs! - Web App'";
var postConfig = {
headers: {
"MYAPP-DOMAIN" : "myapp.bz",
'Content-Type': 'application/json; charset=UTF-8'
}
};
$http.post(postMessageAPI, postData, postConfig).
success(function(data){
$log.log("POST Message API success");
}).
error(function(data, status) {
$log.error("POST Message API FAILED. Status: "+status);
$log.error(JSON.stringify(postData));
});
方法2:失败:
postMessageAPI = "https://myapp-qa.appspot.com/message";
var postData = ({
'conversationid' : '1c34b4f2',
'userid' : '67e80bf6',
'content' : 'Hello champs! - Web App'
});
var postConfig = {
headers: {
"MYAPP-DOMAIN" : "myapp.bz"
'Content-Type': 'application/json; charset=UTF-8'
}
};
$http.post(postMessageAPI, postData, postConfig).
success(function(data){
$log.log("POST Message API success");
}).
error(function(data, status) {
$log.error("POST Message API FAILED. Status: "+status);
$log.error(JSON.stringify(postData));
});
当我使用方法2 时,它在控制台中失败并出现以下错误:
XMLHttpRequest cannot load https://myapp-qa.appspot.com/message.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://0.0.0.0:8000' is therefore not allowed access.
如果您有任何解决方案,请告诉我。提前谢谢。
