我的 URL 是正确的，但我的请求必须是格式错误的。我得到了 400。有什么想法吗？API 文档说，如果传递参数而不是 JSON 正文，它可能会返回 400。提前致谢。

- (void)postFeedItem:(NSDictionary *)paramDict Response:(void (^)(id))callbackBlock Failure:(void (^)())failure {

NSString *targetUrl = [NSString stringWithFormat:@"%@/services/data/v23.0/chatter/feeds/user-profile/%@/", _appManager.coordinator.credentials.instanceUrl, [_appManager.userInformation objectForKey:@"sfUserId"]];

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:targetUrl]];
/*
 { "body" :
 {
 Request body example:
 "messageSegments" : [
 {
 "type": "Text",
 "text" : "New post"
 }
 ]
 }
 }
 */

NSArray *arr = [NSArray arrayWithObjects:
                [NSDictionary dictionaryWithObjectsAndKeys:@"Text", @"type",
                 @"New post", @"text",
                 nil],
                nil];
NSDictionary* info = [NSDictionary dictionaryWithObjectsAndKeys:
                      [NSDictionary dictionaryWithObjectsAndKeys:arr, @"messageSegments", nil],
                      @"body",
                      nil];

NSLog(@"JSON: %@", [[NSString alloc] initWithData:[self toJSON:info] encoding:NSUTF8StringEncoding]);

NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"feed-items" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendData:[self toJSON:info]];
}];

[request setValue:[NSString stringWithFormat:@"OAuth %@",_appManager.coordinator.credentials.accessToken] forHTTPHeaderField:@"Authorization"];
[request addValue:@"false" forHTTPHeaderField:@"X-Chatter-Entity-Encoding"];
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSLog(@"success");
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    NSLog(@"FAILED CHATTER Request: %@ - %@ - %@", [request URL], [request allHTTPHeaderFields], error.description);
}];

[operation start];

}

这是 NSLog：

经过几次尝试，我们发现了这一点。基本上，SFDC 会验证您发送到 Chatter API 的参数的顺序，它会出现。如果这对其他人有帮助，现在可以在 Github 中使用 Chatter 帖子的代码示例：
